| KV1430 VARIABLE CAPACITANCE DIODE FEATURES s Excellent Linearity (CV Curve) s Large Capacitance Ratio (A = 3.70 minimum) with Very Low Series Resistance 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 KV1430 variable capacitance diode was specially made to be used as tuning elements in car radios, radio cassettes, stereos, and other consumer radios. The KV1430 is suitable for wide band tuning from 76 to 108 MHz. If the KV1430 is used only for FM reception, it is possible to operate it at 4.5 V so it is very useful in lowering the power demands of the set. The KV1430 is available in a miniature SOT23-3 package.

Series Resistance measured with HP 4191A or equivalent instruments. The tolerance of two adjacent parts on a reel is within 3% at C2, C4, C6, and C9. The value of capacitance is the average of 2 back to back type diodes. Page 2 January 2000 TOKO, Inc.
