[SVC231]

Features

· Twin type varactor diode having an excellent large

input characteristic and intended for use in low-

voltage (high-voltage) FM electronic tuning applica-

tions.

· Small-sized package (CP), permitting SVC231-

applied sets to be compact and slim.

· Possible to offer the SVC231 devices in a tape reel

packaging, which facilitates automatic insertion.

· High Q.
