TOKOM KV1430TL Datasheet
KV1430
VARIABLE CAPACITANCE DIODE
FEATURES
■ Excellent Linearity (CV Curve)
■ Large Capacitance Ratio (A = 3.70 minimum) with
Very Low Series Resistance
■ Two Diodes in a Miniature Package (SOT23-3)
■ Very Small Capacitance Deviation at Tape/Reel
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.
APPLICATIONS
■ FM Radio
■ Voltage Controlled Oscillator
