Microwave Trimmer Capacitors

Series MTR

This microwave trimmer range provides fast accurate

fine tuning for variety of R.F and microwave appli-

cations. The variety of ten lead configurations provide

for series and parallel stripline and microwave cavity

applications. The MTR capacitors feature an extended

life drive mechanism which gives constant torque, and

confers exceptionally high resistance to shock and

vibration.
