I design a adjustable analog TX-filter in band 40k-500khz. This filter must work in 20W ,and it's capacitor must be 2KV and 1 Amper. Insertion loss of this filter must less than 0.5 db ,and because of it the Q-factor of this capacitor
must greater than 2000.(Q>=2000)
the mica capacitor is very big and I can't use it in adjustable filter. 2KV polypropylene capacitor, can work in 1A ,but frequency range of polypropylene is up to 100khz.
I want capacitor in range 1nf-33nf ,2KV,1A,up to 500 khz,and muximum dimansion were 2.5 X 2.5 X 2.5 cm.
Mica or polypropylene or each suitable capacitor! Where can I find it?

thank you for your help.
