- 150/600 ohm primary to 1200/4800 ohm secondary
- Collector to line or line to base application
- 2.827:1 turns ratio; 0.497 mH leakage inductance
- 0 dbm, 30 Hz - 30 kHz, +/- 1.0 dB max at +0 dbm
- Shielded (pin SH), humbucking, balanced split windings
- Epoxy potted, 9 PCB pins; 500 Vrms; made in Canada
The 560J is a broadcast quality, epoxy potted PCB transformer with a 150/600 ohm primary and a 1200/4800 ohm secondary. It is listed for collector to line or line to base use, giving circuit designers a way to couple transistor stages to 150/600 ohm lines, or to step a line up into a transistor input, in compact broadcast audio equipment.
The 560 Series is built in a rugged black epoxy potted case with 9 pin connections (.025" square by 0.5" long) for P.C. board mounting. An electrostatic shield between primary and secondary is connected to the core and brought out to pin "SH", the construction is humbucking, and balanced split windings on both primary and secondary add circuit versatility; primaries and secondaries can also be reversed for impedance matching. Insertion loss is 1 dB maximum, and higher signal levels are possible with reduced low frequency performance.
Rated output is 0 dbm over 30 Hz to 30 kHz, +/- 1.0 dB max at +0 dbm, with measurements taken without D.C. saturation. Typical values are 15.60 ohm primary DCR, 74.80 ohm secondary DCR, 1.232 H primary and 9.348 H secondary inductance, 0.497 mH leakage inductance and 12.80 K / 95.25 K ohm impedance at 1 kHz. The turns ratio is 2.827:1, dielectric strength 500 Vrms, and the epoxy's workable range -40 to 105C.
Overall dimensions are 1.64" (41.7 mm) x 1.33" (33.8 mm) x 0.85" (21.6 mm) high max. Shipping weight is 0.25 lbs (0.11 kg). Made in Canada; RoHS and REACH compliant, UPC 623980279701.
