KV1440

KV1440 VARIABLE CAPACITANCE DIODE FEATURES s Very Low Series Resistance s Excellent Linearity (CV Curve) s Large Capacitance Ratio (A1 = 1.23 minimum, A2 = 1.65 minimum) s Two Diodes in a Miniature Package (SOT23-3) s Very Small Capacitance Deviation at Tape/Reel APPLICATIONS s FM Radio s Voltage Controlled Oscillator DESCRIPTION The KV1440 is specially made to be used as a tuning element in radio cassettes, stereos, car radios, and other consumer radios. The KV1440 minimizes cross modulation, allowing good signal-to-noise ratio in the overall design. The KV1440 is available in the miniature SOT23-3 surface mount package.
