Mechanical & Schematic Data:

Key Features (850 Series):

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 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" x 1.2" x 1.65" high max.
Shipping weight 0.4 lb.
