How good is Cornell Dubiler Electronics?

[Trinite]

I noticed one of Digikey's capacitor suppliers is Cornell Dubiler Electronics. Is this a reliable manufacturer, or not so much? Seems their production facilities are in the US and Mexico, so seems more promising than a lot of the Chinese/Taiwanese crap out there. Any idea? Not very familiar with non-Japanese manufacturers in regard to quality (as a general rule, I stick to Japanese caps).

Very reliable. No mobo or PSU caps except for the mains cap. Been using them 30+ years.

CDE is the hallmark standard for Silver Mica caps in the range of 1 pF to maybe 100 nF. I haven't used their electrolytics, though - probably not competitive with the Japanese majors.

yep ...CDE ... good stuff .

they have been around for a long time , more than 70 years :

they manufactured for mallory (certain types) .

they also made test equipment ages ago :

a google search for "vintage cornell dublier advertisements" will provide a visual history of the company .

I used CDE silver mica caps on the tuning oscillator of hobby FM transmitters I used to sell.

They were equipped with ceramic caps from the factory. Ceramics are reliable but temperature unstable since they were part of an LC oscillator their capacitance drifted slightly due to changes in temperature. The end result was unacceptable oscillator drift. The last thing you want when transmitting is to drift off frequency.

I put CDE micas in the ceramics place and I had no more issues.

I also use them in tube radio recapping occasionally as well. When ever you need tight tolerances (1%) and temperature stability they're perfect.
