On offer is a useful range of values in 5pc packs at a fair price, with discounts for higher quantities. I have not individually photographed & measured their dimensions: If these details are important for your application let me know specifics and I'll try to help. Likewise if you'd like a custom selection I can create a one-time listing: just let me know ...
Silver micas are my favourite capacitors for RF and audio work. They do not contain organic compounds (plastics), so are reliable over time where other capacitors are not. I don't think I've ever had to replace one as part of a restoration.
They are super stable and handle high frequencies with excellent 'Q' and other parameters. For frequency dependent networks, such as filters and oscillators they're unbeatable.
The larger values, >100pF (except 680pF & 806pF) are 1% precision types. Having close tolerance caps is good where you need multiple matched channels (stereo tone control, I/Q SSB de/modulator - polyphase/all-phase, filters etc.).
The usual downside is the cost, based on the precious metal construction, and the move to surface mount packages. As such they are virtually unused for factory built gear today and found only in custom hand-built equipment for and by radio hams and audiophiles. This collection was assembled over some years, primarily from Australia and the USA - and I bought rather more than I needed.
I have created 3 listings based on max working voltage, one each for 500V, 300V and 100V/unknown. The 500V types are more useful for RF power and valve/tube circuitry where high voltages are present. Most modern semiconductor circuits will be fine with the 300V or 100V types. The unknown voltage types may well be 300V or 500V capable but there's no way of easily checking.
Please take a look at those other listings if the values you require are not listed here.
