TDFZ 170229, TDFZ 170279, TDFZ 170311 product information
RF Power Pot Capacitors for Coupling Purposes, Class 1 Ceramic Dielectric
The ceramic capacitor is housed in a rugged silver plated copper case. This construction allows additional “Beltcontacting” of the outer electrode terminal over the copper can shaft.
The results are short conduction paths with low impedance and low inductance as well as protection of the outer electrode.
