- Humbucking construction with balanced split windings
- RoHS and REACH compliant
The 832A is an 800A Series broadcast-quality interstage audio transformer with a 1:2 ratio. It couples one amplifier stage to the next, stepping a nominal 5K/20K ohm primary up to a 20K/80K ohm secondary, a typical role in tube and discrete amplifier designs.
The maximum primary D.C. unbalanced current is listed as 0, so the primary should not carry unbalanced D.C. Frequency response is +/- 0.5 dB max. from 50 Hz to 15 kHz, insertion loss is approximately 1 dB, and the maximum power level is +15 dBm with the specified characteristics, or higher with reduced low frequency performance.
Humbucking construction helps reject stray magnetic fields, and balanced split windings on both primary and secondary give circuit versatility; the primary may be used as the secondary and vice versa for impedance matching.
It is housed in a deep-drawn steel case with a tin plated finish and fastens with two 6-32 mounting studs, supplied with hardware. Connections are made by wire leads of at least 4" in length. Maximum overall dimensions are 1.75" (44.5 mm) wide x 1.25" (31.8 mm) deep x 2.56" (65 mm) high. The 832A is RoHS and REACH compliant. Its listed shipping weight is 0.58 lbs (0.26 kg), and it is identified by UNSPSC 39121301.
