Capacitor identification, or at least I think it is one. Looks like C1u0 and 9642. Hope you can read it and help me. Thanks.

Re: Cap id
It's an SMD tantalum capacitor. 1uF.
Not sure of the voltage. Nothing in 9642 jumps out at me as a standard voltage. Probably you need the datasheet to find the voltage codes.
Or just guess based on whatever voltage the circuit runs on.
Beware that tantalums mark their POSITIVE side with the stripe."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Thank you for the help.Comment

Re: Cap id
"9642" might be the date code, in the format YYWW.PeteS in CA
Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.

Re: Cap id
Oh yes, the date code. That would make sense...
The leading "C" might be the voltage code, then?"Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Cap id
"A" logo I think is older AVX. Voltage code C is (for AVX parts) 16V.
You can also estimate from the IC's operating voltage.
Tantalum capacitors need a huge voltage derating like 50% for long life. So a 5V IC would have a 10-16V part for decoupling.Comment

Re: Cap id
Speaking of voltage derating, if you're using X7R ceramic caps and don't want much variation due to the voltage coefficient the rated voltage should be 10X the circuit voltage.PeteS in CA

Re: Cap id
Right or wrong, these are what I ordered as a replacement.

Hi Everyone, I am new to this forum. I have a Panasonic LED TV which doesnt turn on and is blinking 4 times repeatedly when I turn on the switch. The TV does not respond to the remote control so I had to turn on using the physical switch on the side of the TV. When I turn on the switch the 4 x blinking starts and repeat itself until I turn off the TV. There is a black screen. I turned off the light in the room to check the panel and I think there is no backlight as far as I can tell.

I found two capacitors on the board and one of the leads on one capacitor had bad soldering joint and the other joint connections not much better and there were several soldering joints that way to much flux around the joint redid several of them
The capacitors were a non brand that I did not recognize they got replaced and now it does not oscillating between relay but what concerns me a little bit is when the voltage is a little bit low the output voltage is around 130 volts and then drops down to 115 volts this happens around 105 to 108 volts if remember correctly

3+1 Voltage Regulator for IMVP-7/VR12 CPUs
Compliant with IMVP-7/VR12, the ISL95831 provides a complete solution for microprocessor and graphic processor
core power supply. It provides two Voltage Regulators (VRs) with three integrated gate drivers. The first VR can be
configured as 3-, 2- or 1-phase VR while the second output is 1- phase VR, providing maximum flexibility. The two VRs share the
serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with the two chip approach.

Hi
Acer A515-43
LA-H801P
Fail: Does not charge battery, has low voltaje on connector.
Laptop didn't want to turn on, only charge led blinked.
I found PQB5 (mosfet high battery charger) in short, voltaje in +12.6V_BATT was 19 v ...
I changed it, changed PQB6 too and now battery charger voltage is 4.4V but battery is 3 cell, 11.25v, then is very low to charging.
Laptop turns on without battery and works fine, but with battery turns on and turns off inmediately, I suspect battery bad but I don't know... -
