identify a capacitor?
i have a plastic cap i think is bad
it has on it
1u k 450vd
what capacitance is this? 1 uf? 1 nf?
many thanks charlie

1uF, 450V rating. Replace with a 630V polyester capacitor with the same pin spacing.Comment

Re: identify a capacitor?
I'm hoping someone could help identify the two large filtering caps in this amp.

Also can anyone comment on the Samwha HE series caps as filtering caps for audio use? Any better 80V 10.000uF low form caps with better performance out there that you could recommend?

Hello everyone,
I have an Dell Inspiron 15 3537 laptop mainboard (LA-9982P Rev. 3.0 (A02)) with a blown SMD capacitor as shown in the attached images. However, there is no printed specifications near the capacitor or a codename for the capacitor to identify the specification of the capacitor to replace it. I wonder how to identify the capacitor since the mainboard schematics are also useless as the capacitors are not named on the board. Any help would be highly appreciated.
Thank You. Stay Safe.

what is the easiest way to measure the capacitance of SMD ceramic capacitors and its rated voltage?...09-12-2024, 01:04 AM

I replaced some capacitor which is located on optical pickup pcb which is shown in the table below(PCB #2).Because it have been out of order.
Now,It works very well,But I just have found that all caps (6svpc100my and other part number as well) ,which is shown in the table below, has ultra-high ripple current spec.
It is not able to obtain any capacitor which can be a substitute for this ultra-high ripple current nichicon capacitor.
So I replaced it with samxon and rubycon's general capacitor(GP,YXA series).
I know that these capacitor will not last as long as nichicon capacitor... -
I want to fix Video door phone which works its doorbell but it is not able to display any screen.
So I disassembled its plastic case and I detached FPC film cable from LCD display in order to inspect LCD display's PCB
I measured ESR resistance of all smd capacitor on this PCB and I noticed that there is some SMD capacitor which has high ESR value(48ohm 50V 0.47uf,15 and 28 ohm 50v 3.3uf,10 and 8 ohm 35v 10uf)
I desoldered this 5 suspicious SMD capacitor like below screenshot.

But I cannot identify specification of desoldered... -
When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.
Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
