Riken resistors no longer in production?

[falcott]

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 🙂

carbon composition resistors

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?

Kiwame, available from percy, parts connexion, and a few other places.

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

for what it is worth, riken is not carbon comp but carbon film.

 

[falcott]

I did a google.
According to these people, Riken is carbon comp...

http://www.thlaudio.com/jpnohme.htm


And according to these people, they are carbon film...

http://www.angela.com/catalog/resistors/Resistors.html


But according to these people, they are carbon comp film !

http://www.audiokitmania.com/resistor.htm


What is the difference 😕

i've asked the same question and rikens are carbon film.

carbon film on a ceramic substrate I think

RIKEN

RM/PSN/PSD series is carbon film.

cessation of production

If something to help.....
