HVC321B
Variable Capacitance Diode for ET tuner
ADE-208-845(Z)
Rev 0
Mar. 2000
Features
•
•
•
•
Low voltage type (tuning voltage 1 to 10V), it is suitable for ET without DC/DC converter.
High capacitance ratio. (n = 10.5 min)
Low series resistance. (rs = 1.0 Ω max) and good C-V linearity.
Ultra small Flat Package (UFP) is suitable for surface mount design.
