dimension will be 0.11” longer.

For a differential trimmer capacitor, the capacitance of one

element increases while the other element decreases, with the sum

remaining approximately constant.

Both elements of a split stator trimmer tune at approximately the

same rate.

General Specifications on page 34 apply except:

1. DC Working Voltage: 500

2. Temperature coefficient: 0±100 ppm/°C.
