KV1370NT VARIABLE CAPACITANCE DIODE FEATURES APPLICATIONS ■ ■ ■ ■ ■ FM Radio ■ Voltage Controlled Oscillator 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) ■ Very Small Capacitance Deviation at Tape/Reel 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 element. A special process provides a very high capacitance ratio in low voltage operation. The KV1370NT is available in a TO92-3 package.
