    I have a Plessey 0.05 Mf 2.5 KV part No 436/1/22010/130 can someone please tell me if this is suitable for use with RF? I also have some E-472 3KV ceramic disc caps are these also suitable for RF use?

    What are your concerns? Have you looked at the manufacturer's specs?

    I am building a Linear amp and the caps are for use in the Rf input to the amp and the decoupling on the HT input. I cant seem to find any information on the caps that I have.

    In general, here are some typical capacitor characteristics.

    Ceramic: 1pF to 22pF - Filtering, Bypass
    Mica: 1pF to 1uF - Timing, Oscillators
    Metal Foil: up to 100uF - DC Blocking, Filtering
    Polyester: .001uF to 100uF - Timing, Tuning
    Polystyrene: 10pF to 10uF - Timing, Tuning
    Paper Foil: .001uF to 100uF - General Purpose
    Tantalum: .001uF to 1,000uF - Bypass, Coupling, DC
    Aluminum: 10uF to 220,000uF - Filtering, Bypass
