TOKOM KV1450TL Datasheet
KV1450
VARIABLE CAPACITANCE DIODE
FEATURES
■ Very Low Series Resistance
■ Excellent Linearity (CV Curve)
■ Large Capacitance Ratio (A1 = 4.60 minimum)
■ Two Diodes in a Miniature Package (SOT23-3)
■ Very Small Capacitance Deviation at Tape/Reel
DESCRIPTION
The KV1450 variable capacitance diode was specially
made to be used as tuning elements in car radios, radio
cassettes, stereos, and other consumer radios. The
KV1450 is suitable for wide band tuning from 76 to 108
MHz.
If the KV450 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 KV1450 is available in the miniature SOT23-3 package.
