you are right first i took size code (length and width) then datasheet then thickness then circuit comparision for finding capacitor voltage (because too many voltage values are available in same thickness) at final stage i found 16V 10uF, 16V 22uF, and 16 V 47uF, if the capacitor is damaged then we can select any one of these 3 and testing the ripples at output stage for best fit component
well, he did narrow it down to 3 values. If you have a 2nd capacitor the same size on the board you could measure it. If no schematics are available you may just go with the largest value of that size and it could work. If still not lucky then try the smallest size. usually largest size will work because voltage is higher just the bigger ones cost ore and might not fit. I usually salvage something same size or bigger and just try it. I fixed a macbook the other day and just fitter a random cap, larger than the apple capacitor. It worked..
@@izzzzzz6normally if its light colour( white)the value is rated as pF, if its light brown it could be nF if its dark brown its uF(sometimes nF but bigger values) Thats what we noticed in the manufacturing company However some people saying its more about the material they have used, but whenever i have done the programs this theory was always worked for me.
He did show how to find the data sheets for these surface mounted capacitors. I had no idea how to do that before. He narrowed down the possibilities, and then seemed to confirm the hypothesis. Thank you, Haseeb. You are an inspiring teacher. Your content has made me a much more skilled technician
Hi, thank you for sharing this video. As you showed us, there are many capacitor ratings for the same capacitor dimensions. Here you were able to measure one good capacitor, but if that capacitor may be in short (reason for us to be checking for its value in most cases), it would be very hard to say for sure which capacitor should we be replacing... Could you please explain to us how can we proceed in case of a failed capacitor? Thank you very much. Greetings.
@ruimonteiro7523 first of all thanks for your valuable words in case a damaged capacitor, and we have multiple choices, then it is to try one by one and to find the result of the circuit
Thank you for sharing the decode method.I didn't know it, great. The SMD codes are always a pain. Several times I had semiconductors with codes I couldn't find in SMD code books or the Internet. In this cases a repair was not possible. Resistors have 2 code schemas too. Very sad. 😢😢
best regards for your valuable comment yes the SMD codes are a biggest headache, actually it is step to make thinks non-repaireable. that is the reason most of the SMD parts are coded with some unknown marking and the codes are not revealed anywhere
Well defined video. The value would be anyones guess if you had a burnt cap, but if you do some math on the circuit in question, you can arrive at the value,like he did when he identified the chip on the board.Even though the datasheet showed pin 4 useda 10, it was actually a 22. Likely a timing/speed change in operation, or ripple supression as he answered in his post
As MLCC production techniques have improved considerably over the years you would also need to cross reference the approximate date of production of the circuit board with the datasheets you are using. In general though, desolder such a capacitor and measure it's capacitance as you showed. Then infer a suitable voltage rating based on other components in circuit. Then your good to go. There are other parameters that can be important. Dialectic strength for example. Although this is indicated by the color of the MLCC capacitor.
yes there are too many approaches to find some closest match of the required component. by measurement by chedcking datasheet of the main ICs by finding similar circuit by searching schematics or service manuals
Masha Allah tbarek Allah, thank you so much for thus great explanation. May I ask what's the best temperature used and air flow level by hotairgun to desolder components avoiding destroying components and the board itself?
Thanks a lot dear brother 💕 We must consult datasheet for reflow soldering Temperature and maximum permissible time for hot air rework For example 240 degree for 5 second Or 300 degree for 3 second etc
Hocam neden üzerine kodlarını yazmıyorlar üreticiler, bizi neden uğraştırıyorlar. Amaçları nedir. Smd dirençlerin üzerine yazıyorlar kondansatörlere neden yazmıyorlar. Bir makul sebebi var mı?
Gracias especiales por sus valiosas palabras. De hecho, es muy difícil decodificar y comparar las medidas con las hojas de datos para obtener las piezas exactas.

I think it would be much faster to use a good LCR-meter and measure the capacity. You can guess the voltage rating from the application or like you did with checking parallel components. Its not a problem when the voltage rating is a bit higher, but it shouldn't be less than the original.
My brother, you are not calling me a professor. You are a doctor. Could you please make a video of the device that you use to remove electronic elements from the board of this device that resembles an iron? Your student is from Egypt.
You are lucky , cap is in good condition , and not schort. If not ? Little advice...hot them , and check capaticance ...then find what kind of dielectric is.
Dear Haseeb, Thank you for your videos. I want to run a 1.5 volt wall clock with a 3.7 volt 18650 lithium battery. How do I do this? Please make a video or a short.

Bu kondansatörlerin miktarını hiç araştırmamıştım ve hep o kondansatörün etrafındaki parçalardan almaya çalıştım. -tüketici ve sinir bozucu. Çeviri yapmak için Google'dan yardım aldım. Umarım anlarsınız. Size ve ailenize sağlık ve uzun ömürler dilerim.
Que complicado son las compañías con los componentes smd en ves de poner a un lado el valor escrito en la placa asi de fácil pero bueno compañías maliciosas

Why have you used C35 in the first part of your video and then remove C37 So what value is C35 ?
both are same. as C37 was at a corner, so i preferred to remove it
in upcoming sessions i am planning to decode the other size codes
