Riken resistors no longer in production?

falcott · 29th November 2006, 05:51 PM

Hi, I've just heard from Parts Connexion that Riken is no longer in production.

Just thought I'd let you know...

Any other news/comments?

old news already

Who else still makes them?

I never liked the Riken carbon comp resistors because of the gold plating on the leads. I don't think it does any good for the solder joints -- gold is good for connectors, but not soldering ...

Anyway, I think Ohmite probably still makes carbon comp resistors, maybe Xicon. Anyone else?

I just ordered some little carbon comp Ohmites...they go by the trade name Little Demons

Any good?

I know some ..
If RIKEN is resistor saying "Rikenorm" in japan ,
so they are to be selling now only stock.
http://www.wakamatsu-net.com/biz/
this is very famous shop at AKIHABARA in JAPAN say "WAKAMATU"
but I dont know to be able to buy from other country.

I attach the list with some translate Jananese to English.

Is there anything inherently wrong with carbon composition resistors for use in chipamps? I've heard pros and cons:

Cons

1- have more drift and noise

2- may break down with sustained high temp use

Pros

1- have a warmer tone...maybe due to our perception of drift

2- old school?

Peter Daniel perfers them in his chip amps:

also mentioned in other threads.

Old skool I like!

www.ae-europe.nl is advertising with Rike Ohm resistors on their site, so.....

I should mention I stock: NOS RC (Commercial) RCR (Mil -Spec)
Allen- Bradley
IRC International Resistance Corp
Airrco- Speer
Stackpole
TRW
Ohmite
And others in Carbon Comp resistors
1/8W - 1/4W - 1/2W - 1W - 2W

Most people prefer the Allen-Bradley but since these are so hard
to find depending on the value they will settle for other Manufacturer's
