Re: Fake Nichicons?

Eventually I got to look at another definitely genuine Nichicon and the weight is 45 grams and looks identical. So the weights listed on sites like mouser are not accurate. At least I can confirm that the cap is original and the other caps from this seller are also original, which is a relief as I had already replaced about 50 smaller caps.

Re: Fake Nichicons?

Hi,

Thanks for your reply, I will take measurements and check them out. The weight difference worries me, but the weight came from a mouser page not an actual data sheet (couldn't find weights on the data sheets).

I'm inclined to believe the seller that he only buys from trusted sources. Just the weight bothers me ( I'm used to checking 18650 batteries for weight as it is a good indicator of authenticity).

Ok I checked the sizes for 4 different caps that he supplied me and the sizes are all spot on.

I haven't...

Re: Fake Nichicons?

I sent them a message but can't send pictures until/unless they reply, will have to wait and see, thanks for the help.

While I wait I have taken another couple of photos, just in case someone sees something obvious in them....

That was my first thought to email Nichicon but I haven't been able to find an email address, which is why I looked for help here.

Hi,

I have recently received some Nichicon LKS1J103MESB 10,000uf 63v capacitors. They felt very light when I picked the up so I decided to weigh them. On my admittedly cheap scales they weigh 46grams the spec sheet says they should be 59grams. I tried them on 3 sets of scales and the readings are the same. The seller says that he only buys from mouser and digikey.

Is it possible for them to be real Nichicons? I really want them to be genuine it would save much time and effort. I am recapping an old Audio Dynamics ca2000e amplifier (I know it is an obscure make but...

Re: The Hall of Shame - Badcaps Photo Montage

Hi,

My old Audio Dynamics amplifier (ca2000e) started to take time to power on, sometimes 10 seconds sometimes 10 minutes. The filter caps appear to be the problem, 2 of them are starting to bulge on the top, not to easy to see in the photos. They all check out ok on a peek esr meter so I guess that these type of meters are of limited use in testing capacitors.

Anyway they will be replaced....
