KV1370NT
VARIABLE CAPACITANCE DIODE FEATURES
s s s s Very Low Operating Voltage (1 to 4.5 V) Excellent Linearity (CV Curve) Large Capacitance Ratio (A = 5.00 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 KV1370NT variable capacitance diode was specially developed for use as tuning elements in car radios, radio cassettes, and other consumer radios. Single package construction includes an antenna and oscillating tuning e l e m e n t . A special process provides a very high capacitance ratio in low voltage operation. The KV1370NT is available in a TO92-3 package.
