The 801A is a broadcast-quality audio transformer from the 800A Series for isolating and matching duties in low-impedance audio lines. Both the primary and the secondary are rated at a nominal 50/200 ohms, so it passes signal at the same impedance while breaking ground paths between pieces of equipment, a common need for audio integrators and broadcast engineers.
The primary tolerates up to 0.8 mA of unbalanced D.C. current. 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. An electrostatic shield sits between the primary and secondary windings.
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 801A is RoHS and REACH compliant. Its listed shipping weight is 0.6 lbs (0.27 kg), and it is identified by UNSPSC 39121301.
