Silicon Tuning Diodes
6.8–100 pF, 30 Volts
Voltage Variable Capacitance Diodes
These devices are designed in popular plastic packages for the high
volume requirements of FM Radio and TV tuning and AFC, general
frequency control and tuning applications. They provide solid–state
reliability in replacement of mechanical tuning methods. Also
available in a Surface Mount Package up to 33 pF.

admittance bridge at the specified frequency and
substituting in the following equations:
