Transformers & Chokes

• 150/600 Ohm Primary Impedance
• 300/1200 Ohm Secondary Impedance
• Deep-drawn steel case with tin plated finish, with two convenient 6-32 mounting studs with mounting hardware.
• Sealed case and wax potted core internally for stable characteristics and long life.
• 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 the green lead.
• Humbucking construction
• Balanced split windings on pri. & sec. for circuit versatility. Primary may be used as a secondary and vice versa for impedance matching.
• Lead length: Min. 4"
