[R-390] Orange Drop vs ceramic disc

[Shoppa, Tim]

Orange drops are capable of handling very high pulse currents. This is important in snubbers in power equipment etc. Note that this is what Sprague sells them for. There will be few places in a radio where this characteristic is needed.

Ceramic discs with wire leads are still available and have superior HF characteristics (lower inductance) and will be superior in most all bypass applications. Audio applications, ceramics are not so clearly a win.

Note that many lines of leaded ceramic discs are being phased out in favor of surface mount components. I'm not pronouncing that the leaded parts are disappearing, I'm sure they'll be around for another century, but realize that 90% + of current production needs are surface mount. Surface mount ceramics also have impressively low lead inductances important for many applications today.

I'm working on a radio and now need to buy some capacitors.  My
understanding is that the old round flat ceramic disc don't age.  Any
opinions either way on Orange drops vs  ceramic disc.
