TOKOM KV1370NT Datasheet
KV1370NT
150
VARIABLE CAPACITANCE DIODE
FEATURES
■ Very Low Operating Voltage (1 to 4.5 V)
■ Excellent Linearity (CV Curve)
■ Large Capacitance Ratio (A = 5.00 minimum)
■ Two Diodes in a 3 Lead Through-Hole Discrete
Package (TO92-3)
■ Very Small Capacitance Deviation at Tape/Reel
DESCRIPTION
The KV1370NT variable capacitance diode was specially
developed for use as tuning elements in car radios, radio
cassettes, and other consumer radios. Single package
construction includes an antenna and oscillating tuning
element. A special process provides a very high
capacitance ratio in low voltage operation.
The KV1370NT is available in a TO92-3 package.
