TOKOM KV1440TL Datasheet
KV1440
VARIABLE CAPACITANCE DIODE
FEATURES
■ Very Low Series Resistance
■ Excellent Linearity (CV Curve)
■ Large Capacitance Ratio (A1 = 1.23 minimum,
A2 = 1.65 minimum)
■ Two Diodes in a Miniature Package (SOT23-3)
■ Very Small Capacitance Deviation at Tape/Reel
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.
