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.
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.
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)
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
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...
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%.

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.

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.czcams.com/video/u6wZu2ZBpIo/video.html Thank you.

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.

100nF means 104 pF (Choose capacitor with 104 Written on it)
Yes.

They are found in different printed values such as 100n, 104 and 0.1, depending on the manufacturer.

For 100pF it should be mentioned like: 101 over capacitor.
No friend.
100 or 101 indication is for 100pF.
Similarly,
150 = 151 = 150pF

What if the ceramic disc capacitor has no markings?
You mean no any numbers or letters have printed?
