Yes, and unlike plastics, their mechanical resonance is sharp and at frequencies where microphonics matter a lot. Even then, a 4.7uF SMD multilayer ceramic mounted with two "looped" wires for stress-relief worked just fine. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
