HVC376B

HVC376B Variable Capacitance Diode for VCO ADE-208-687 (Z) Rev 0 Oct. 1998 Features High capacitance ratio (n=4.3min) and good C-V linearity. High Q circuit can be composed due to low series resistance. (rs=0.8Ωmax) To be usable at low voltage. Ultra small F lat P ackage (UFP) is suitable for surface mount design.
