- This video provides a clear guidance to read polyester film and ceramic capacitors printed with various codes. These codes describe their capacitance, voltage and tolerance values. This guidance and explanation is much important when replacing capacitors with new ones having different codes, but same values. Also useful for beginners when dealing with capacitors.
I am a Hobbyist 13 year old I have build almost 10 -15 fm transmitter circuits but i read capacitor code wrong now I build them again it works ^_^ thanks a lot buddy you deserves more
You are welcome friend.
Will anyone tell me what does the "B" mean in the minute: 1:33 (blue capacitor), mine starts with an "R" and ends with a "UK" or "U
R = Temperature characteristics
Capacitance change within +/-15% at -25 to +85°C temperature range.
Capacitance change within +15% and -30% at +85 to +125°C temperature range.
472 = Capacitance value
472 = 4700pF = 4.7nF = 0.0047uF
K = Capacitance tolerance
+/-10% = +/-470pF = 5170pF or 4230pF
I have a doubt about the code UK
If it 1K, 2K, 3K or 6K, the maximum DC voltage is 1kV, 2kV, 3.15kV or 6.3kV respectively.
@@hobbyelectroniccircuits7391 Thank you so much, other suggest it's no "UK" they stated that it's more like the brand's name something like "U
You are welcome.
Good luck with your work 🙏
Thanks for the video, and great music. Who is?
Thank you..

Sir muje 47 pf chahiye lekin market me mil nahi raha. To 47pf ke badle 100pf laga sakta hu????
Replacing 47pF with 100pF depends up on your application. It is not suitable for radio frequency circuits. But it is ok for ordinary and basic circuits. Also you can connect two 100pF capacitors in series to obtain 50pF one, which is nearly equal to 47pF.
Great video! Simple clear information none of the BS I have found on other channels. Well, bloody done mate!
Thank you very much for admiring my work. 👍
muchas gracias me resulto útil
You are welcome friend 😊
@ 1:04 Is this a mistake?
Code 100: = First = 1, Second = 0 = Third = 0
This is supposed to be 10pf right?
No it is not a mistake.
Code 100 is a direct pF value printed in ceramic capacitors. Code for 100pF is 101.
Some manufacturers print direct value as 100, rest print 101 code. Both are the same.
100 = 101 = 100pF
220 = 221 = 220pF
470 = 471 = 470pF
@@hobbyelectroniccircuits7391 Thanks for clarifying, that was tricky specially on exams.
You are welcome...
1:09 here second capacitor value should be 10 Pico Farad right?
For 100pF it should be mentioned like: 101 over capacitor.
No friend.
100 or 101 indication is for 100pF.
Similarly,
150 = 151 = 150pF
470 = 471 = 470pF
@@hobbyelectroniccircuits7391 thank you friend 👍
Friend, I got confused by this capacitor: GQM1875C2E680JB12D (Part number)
In datasheet it is given that 68pF for the 680 represented in the part number.
Can you clarify this friend?
680 may be the part number in your datasheet, but you cannot decide it as 68 or 680pF without refering the description.
For a 68pF capacitor it should be printed the number 68 on capacitor and for a 680pF capacitor it should be 680 or 681.
Thank you
Thankx a lot bro😮
You are welcome 😊
Great video! Exactly what I was loolking for. But one question remains: if there is no tolerance letter after the capacitance value, what then is the tolerance?
Thank you 😊
If there is no tolerance letter, assume as the worst case scenario.
Shot this helped ❤
Thank you...
My blue poly capacitor reads
l 0 2 J :
A2JF :
It’s on a tv power board , can u help ?
102 = 1000pF = 1nF = 0.001uF
J is for +/-5% tolerance.

My ceramic capacitor reads
F
104
25V
KCK
im confused for identifying this
Capacitance value 104 = 100000pF = 100nF = 0.1uF
Maximum voltage = 25V.
F is the tolerance code (1%).
KCK is the capacitor manufacturer.
Very good video. I do electronics for a hobby, mainly just replacing faulty components. I bought some ceramic capacitors (marked 104) from a reputable dealer. When I tested them all, they read around 37nf. Are these faulty, or is my meter no good? The meter I use is a LCR-T4, one of those inexpensive Chinese brands. I read somewhere it may have something to do with something called bias effect.
Thank you for admiring my work.
I too do electronic works as a hobby, not in commercially.
104 means 100nF and the value shown in the multimeter (37nF) is two or three times less than the printed value.
We can't exactly determine whether the multimeter reads incorrectly or the capacitors are faulty. But I think it is better to test those capacitors with a branded multimeter, because some cheap multimeters do not sense properly for small valued capacitors.
Also use box type capacitors in cases where high accuracy and reliability is needed.

How big voltage capacitor for guitar ? Or only value for passive circuit?
I didn't get you friend 🤔
Hi experts, may I know how to read the capacitor. Let say the label on the capacitor is 250uf and 25v. Does it mean it can store up to 250uf when 25v is applied? What if I apply a lesser voltage let's say 2 volt?
250uF / 25V means it is safe to use this capacitor upto 25 volts and its capacitance is 250uF. Higher the capacitance more energy it will store.
Charge (coulomb) = Capacitance (farads) × Voltage (volts) = Current (amperes) × Time (seconds)
@@hobbyelectroniccircuits7391 Thank you very much.
You are welcome.
Please refer those equations and definitions of terms to get an idea💡
I have a ceramic capacitor and what is the meaning of Y5S .1M 25V?
Y5S is the temperature coefficient.
0.1M = 0.1 Micro Farads = 100nF = 100000pF = 104 (code).
Maximum voltage is 25V
Ye to aapne capacitor ka value read karna nikala na aapne, abhi diwali aa raha , agar apan 50 led 5mm RGB series mai lagate h to apne ko kitna capacitor value chahiye hoga uspe banao bro
There is a video in my channel named "230V LED bulb circuits", for white LEDs. But it is not good to connect large number of (50) RGB LEDs in series because they are not similar exactly and weakest LED will burn over certain time. One solution is make series sets using only ten LEDs for each set and connect those five sets together in parallel. Then use 224/400V or 474/400V polyester film capacitor, 470k resistor, four IN4007, 10uF/400V capacitor, 27 to 30V/1W zener diode to make the driver. Here are some of white LED projects, you will get basic idea through them. m.th-cam.com/video/u6wZu2ZBpIo/w-d-xo.html
Thank you.
100nF means 104 pF (Choose capacitor with 104 Written on it)
Yes.
0.1uF = 100nF = 100000pF = 104 (code)
They are found in different printed values such as 100n, 104 and 0.1, depending on the manufacturer.
Very good information video Sir 👏👌 can you tell me please 364j 400v ceramic capacitor how to read ??
Thank you for admiring my work.
364J 400V
364 = 360000pF = 360nF = 0.36uF
J for tolerance of +/-5% (0.36+5% or 0.36-5%)
400V is the maximum voltage that can withstand.

The ceramic capacitor has code 104 Z5. What does "Z5" mean?? Can I put a capacitor of value 104 Z2 in its place??
104 = 100000pF = 100nF = 0.1uF
Z is the tolerance (+80% & -20%)
Code 5 is for max. voltage of 50V.
Code 2 is for max. voltage of 200V.
So it is possible to replace 104 Z5 by 104 Z2
Wow! Thank you very much for the enlightening information. I have to repair an expansion card for an Apple Plus computer with the 104 Z5 capacitor broken, but I only have the 104 Z2 capacitor in stock...
You are welcome friend.
There are several special codings of those capacitors that are not given in my video because they are not very common.
Very well outlined and precisely explained
Thank you very much...
Jitna log bol k nahi samjha pata utna aapne animation mai samjha diya, superb bro, I challenge itne se video mai koi itna ,
Thank you very much....
Mil gracias! Siempre fue una adivinanza saber los valores de estos componentes. Menos mal que ahora existe internet. Muchas gracias!

Thank you.. 😊
Maybe someone here can help me. I have a board that has 22 and 33 ceramic capacitors both with underlines and SEC. Now I have ben able to determine the SEC is manufacture and 22 and 33 are 22 pF and 33pf. Not sure if the line means anything or how i can determine the voltage. Any help would be greatly appreciated.
Normally this type capacitors (I guess orange color ceramic capacitors) have a low maximum voltage less than 50V.
Tolerance is not specified and may be higher than 10%.
@@hobbyelectroniccircuits7391 that k you. It's for my rowing machine and it's easily 15+ years old. Was very disappointed the display suddenly stopped. I will try it and hopefully I get lucky.
@@hobbyelectroniccircuits7391 sorry one more question do you think I can use a multilayer rather that radial? Seems easier to find. Unless you know someplace?
Use the same pF value.

What if the ceramic disc capacitor has no markings?
You mean no any numbers or letters have printed?
So you cannot determine its value as well as cannot confirm it is a capacitor.
