Someone mentioned that ATC makes the 100E series of transmitting 
ceramic capacitors, which have wide straps for leads (or can be SM).

Murata Erie has also made similar parts, and they can be found 
surplus from SSof Nebraska. Also, they may be bought from Newark 
Electronics with a credit card.

I want to also bring attention to two lines from Europe, which are 
distributed by your friendly Richardson Electronics $ales person:
Morgan Matroc Limited carries the Unilator line (U.T.C.) of ceramic 
capacitors. Their type 103, 104 and 105 are monsters for RF current 
carrying. They are made in the UK. The other company is Draloric, 
which makes the 1000Vp rated MPC 7520, which can carry about 100 Amps 
RMS in a 100pf, 230 Amps for 510 pf. Tempcos aren't great for these 
large caps (N750) but if they are used for bypass or blocking and not 
in high Q circuits, they are OK. For 2 kVp, they have the KF1008 
which is similar to the ATC 100E, for 11.3 Amps RMS.
