KV1350NT
VARIABLE CAPACITANCE DIODE FEATURES
s s s s Very Low Operating Voltage Excellent Linearity (CV Curve) Large Capacitance Ratio (A = 4.6 minimum) Two Diodes in a 3 Lead Through-Hole Discrete Package (TO92-3) s Very Small Capacitance Deviation at Tape/Reel
APPLICATIONS
s FM Radio s Voltage Controlled Oscillator
DESCRIPTION
The KV1350NT variable capacitance diode was specially made to be used as tuning elements in car radios, radio cassettes, stereos, and other consumer radios. The KV1350NT is suitable for wide band tuning from 76 to 108 MHz. If the KV1350NT is used only for FM reception, it is possible to operate it at 4.5 V so it is very useful in lowering the power demands of the set.
