TO99 age and reliability

TO99 age and reliability | 24 January, 2001

I�m suddenly getting a very high failure rate in a TO99 component (National LM136AH-2.5). After some investigation we found some of these parts are more than 20 years old. What I am hoping for is that someone out there can help me find some standards on how old different packages can be before they need to be thrown out.

Thank you, Travis

Interesting. I'd start with the "Help Desk" at the Reliability Analysis Center [http://rac.iitri.org/].

Please get back with your findings.
