Features

Deep-drawn steel case with tin plated finish, with two convenient 6-32 mounting studs

with hardware.

Hermetically sealed for stable characteristics and long life. Header has nine 0.22" long

solder terminals.

Wide frequency response +/- 0.5 db max. from 20 Hz. to 20 Khz. (except units over 5K

ohms impedance, may be down 1 db @ 20 Khz.)

Insertion loss of apx. 1 db.

Maximum power level +15 dbm. with specified characteristics, or higher levels with

reduced low frequency performance.

Distortion is apx. 1.5% @ 20 Hz. under full power.

Electrostatic shield between pri. & sec. connected to terminal 9.

Humbucking construction

Balanced split windings on pri. & sec. for circuit versatility. Primary may be used as a

secondary and vice versa for impedance matching.

Overall dimensions 1.7" (43.2 mm) x 1.2" (30.5 mm) x 1.65" (41.9 mm) high max.

Shipping weight 0.4 lb. (0.18 kg)
