| KV1310NT VARIABLE CAPACITANCE DIODE FEATURES s Very Low Operating Voltage s Excellent Linearity (CV Curve) s Large Capacitance Ratio (A = 2.20 minimum) with Low Series Resistance s 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 KV1310NT variable capacitance diode was specially developed for use as tuning elements in car radios, radio cassettes, and other consumer radios. The KV1310NT minimizes cross modulation; thus allowing good signal-to-noise ratio in the overall design. The KV1310NT is available in a TO92-3 package.
