Re: Non-electrolytic capacitor manufacturers
I guess Fujitsu will be one of them...not really experienced in this area of research, but maybe some of the major japan brands have something to do with this.Mobo: MSI K8N Master2-FAR CPU: 2x Opteron 265 OC'd @ 2,25GHz RAM: 2x2GB Crucial DDR400 CL3 ECC/Buff. (ECC OFF), VGA: ASUS HD6950 2GB Reference edition FLASHED TO HD6970 HDD: 80GB ATA133 Seagate ,OnBoard: 2xGLAN, 8-Ch. Realtek audio, USB2.0/Firewire, PCIe Physx card PSU: 850W Corsair AX Case: Cooler Master HAF932 + NZXT 5 Fan Controller. -

There are a wide variety of completely different kinds of 'non-electrolytic' capacitors.

Re: Non-electrolytic capacitor manufacturers
Wax capacitor is one of the non-liquid caps, poly caps as well in several types of plastics. I know in 1980s electronics teacher had us cut apart old wax caps and unroll them to learn what internal structure of old caps are.

Hi people, I hope this is the correct spot to post this, I'm new to the forum.
I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.
I hope these photos make it clear which component I am referring to:
(yes, the soldering is a bit botched from removing the blown one, I know)
I have found the board schematic (attached), but there does not seem to be a boardview available. I have never... -
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 desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm
And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,... -
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.
Rubycon YK DataSheet (b... -
a few days ago I finally purchased mser-100 v2 and I tested its abillity of measuring ESR value.
I found that It shows pretty accurate ESR value for electrolytic capacitor,But When I measure polymer capacitor of dreamcast game console,I found that one third of polymer capacitor's ESR value is more than twice the value of ESR meter table.(for example, I measured one polymer capacitor of 6.3v 100uf, It showed ESR value of 7.68)
Although my dreamcast now turns 20 years old but it still works. I occasionally have played game with it.
Is this ESR value of polymer capacitor correct?...
