TOKOM KV1420TL Datasheet
KV1420
VARIABLE CAPACITANCE DIODE
FEATURES
■ Very Low Series Resistance
■ Excellent Linearity (CV Curve) with Very Wide
Operating Range
■ Large Capacitance Ratio (A = 2.57 minimum)
■ Two Diodes in a Miniature Package (SOT23-3)
■ Very Small Capacitance Deviation at Tape/Reel
DESCRIPTION
The KV1420 is a high withstanding voltage variable
capacitance diode specially designed for high grade stereo
tuners. Superior linearity characteristics and a high
start-up voltage (7 V) provide for strong input characteristics
which make it highly suited to provide a strong front end in
mimimizing cross modulation.
The KV1420 is available in a miniature SOT23-3 package.
