The Audio Type Transformers 560, 800 and 850 series. Broadcast quality audio transformer.

Key Features (560 Series):

• Rugged black epoxy potted case with 9 pin connections (.025" square by 0.5" long).

• Frequency response @ 0 dbm +/- 1 db max. (+/- 0.5 db is typical) of 30 Hz. to 30 Khz., except 560Q which is 30 Hz. to 15 Khz.

• Insertion loss of 1 db max.

• Maximum power level 0 dbm.

• Electrostatic shield between pri. & sec. connected to core and pin "SH".

• Humbucking construction

• Balanced split windings on pri. & sec. for circuit versatility.

• Primaries and secondaries can be reversed for impedance matching.

• Overall dimensions 1.64" x 1.33" x 0.85" high max.

• Shipping weight 4 oz.

Mechanical & Schematic Data:

Key Features (800 Series):

• 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 pins.

• Frequency response +/- 0.5 db max. from 50 Hz. to 15 Khz.

• Insertion loss of apx. 1 db.

• Maximum power level +15 dbm. (except 841, 842 & 844 which are +20 dbm) with specified characteristics, or higher levels with reduced low frequency performance.

• 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 1.75" wide x 1.25" deep x 2.56" high max.

• Shipping weight 0.5 lb.

Notes:

* Electrostatic shield between primary & secondary

** Single plate requires parallel feed. When operating at impedances below nominal, power capability is lower and the frequency spectrum is shifted downward, conversely, at higher impedances power capability and frequency spectrum will be shifted upward.

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.
