- Vertical P.C. board mount, split bobbin design
- 4.4 VA size is non-concentric wound; low primary-to-secondary coupling, no electrostatic shield required
- Hipot of 2,000V RMS and Class B insulation rated 130 degrees C
- CSA certified (File # LR3902) and UL recognized (File #E207860)
- RoHS and REACH compliant
- Dual-primary 115/230V, 50/60 Hz equivalent: 160G12
The 161GA12 is a low voltage, P.C. board mount vertical power transformer from the 160-161 Series, built for OEM engineers and designers who need a board-level AC supply from a 115V line. It is rated 4.4 VA with a single 115V primary for 60 Hz operation only, the economical single-primary version of the dual-primary (115/230V, 50/60 Hz) part 160G12.
It supplies 12.6V centre-tapped at 350 mA in series, or 6.3V at 700 mA with the secondaries in parallel, from the 4.4 VA frame. Secondary ratings are given in RMS values.
Construction is a vertical mount, split bobbin design, and the 4.4 VA size in this series is non-concentric wound. Low primary to secondary coupling means no electrostatic shield is required. Insulation is Class B (130 degrees C) with a hipot rating of 2,000V RMS.
In the series mechanical data for the 161 Series, the 4.4 VA size lists overall dimensions A 1.69 in, B 1.25 in and C 1.45 in, with a G dimension of 0.40 in. The part ships at 0.4 lbs (0.18 kg). The series is CSA certified (File # LR3902) and UL recognized (File #E207860), and the 161GA12 is listed as RoHS and REACH compliant.
