KV1460 VARIABLE CAPACITANCE DIODE FEATURES APPLICATIONS ■ ■ ■ ■ ■ ■ FM Radio ■ Voltage Controlled Oscillator ■ Battery Operated Products Very Low Operating Voltage (1 to 6.5 V) Excellent Linearity (CV Curve) Large Capacitance Ratio (A1 = 4.70 minimum) Two Diodes in a Miniature Package (SOT23-3) Very Small Capacitance Deviation at Tape/Reel DESCRIPTION The KV1460 variable capacitance diode was specially developed for use as FM tuning elements in car radios, radio cassettes, and other consumer radios. The KV1460 uses a special process to provide a very high capacitance ratio in low voltage operation. The KV1460 is available in the miniature SOT23-3 surface mount package.
