NOTES:
* Electrostatic shield between primary & secondary
** Single plate requires parallel feed. When operating at impedances below nominal, power capabil-
ity is lower and the frequency spectrum is shifted downward, conversely, at higher impedances
power capability and frequency spectrum will be shifted upward.

Part
No.
Deep-drawn steel case with tin plated finish, with two convenient 6-32 mounting
studs with hardware (same as 800 series except low profile).
Hermetically sealed for stable characteristics and long life. Header has nine
0.22" long solder terminals.
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 primary & secondary connected to terminal 9.
Humbucking construction
Balanced split windings on primary & secondary for circuit versatility. Primary
may be used as a secondary and vice versa for impedance matching.
Overall dimensions 1.7" x 1.2" x 1.65" high max.
Shipping weight 0.4 lb.
