Create Free Business AccountThe 162H10 is a 20VA low-profile power transformer for printed circuit board mounting, built with a universal dual primary rated 115/230V and a 10V center-tapped secondary rated 2A RMS in series connection. Wired in parallel, the two secondary windings deliver 5V at 4.0A. It suits OEM engineers and designers who need one board-level transformer for equipment that may run from either 115V or 230V mains at 50/60 Hz.
Construction uses a split bobbin with dual, non-concentrically wound secondaries, which keeps primary-to-secondary coupling low so no electrostatic shield is required. Insulation is Class B (130 degrees C) and the part is hipot rated at 2,500V RMS; the drawing specifies the primary-to-secondary test as 2500V, 60Hz for 1 second. The unit is designed so that all windings must be used, and pin numbers are embossed on the bobbin flange for identification.
On the series mechanical table the H-size body measures 2.25 in long, 1.88 in wide and 1.44 in high, with a listed weight of 0.8 lbs; the shipping weight is 0.8 lbs (0.36 kg). It is a P.C. board mount design with industry standard pin spacing and two-hole mounting for #4 screws; mounting screws are not provided.
Electrical test acceptance criteria on the 162H10 drawing include a maximum excitation current of 91.2mA at 115V, 60Hz across pins 1–2, secondary no-load voltages of 6.118V on each winding (pins 5–6 and 7–8, ±2%), and DC resistance at 20°C of 69.51 Ω per primary winding and 0.227 Ω per secondary winding (±20%). The part is RoHS and REACH compliant and the series is c UL us recognized. A single 115V primary version of the same output is listed as 164H10.

Yes. It has a universal dual primary rated 115/230V for 50/60 Hz operation. If you only need 115V input, the single-primary equivalent is 164H10.
Connected in series the secondary gives 10V C.T. @ 2A (RMS); connected in parallel it gives 5V @ 4.0A. The transformer is rated 20VA and all windings must be used.
It is a P.C. board mount with industry standard pin spacing and two-hole mounting for #4 screws. Mounting screws are not provided.
The series mechanical table lists 2.25 in (L) x 1.88 in (W) x 1.44 in (H), with a weight of 0.8 lbs. Shipping weight is 0.8 lbs (0.36 kg).
No. The split bobbin design gives low primary to secondary coupling, so no electrostatic shield is required.
Class B insulation rated 130 degrees C, a 2,500V RMS hipot rating, c UL us recognition for the series, and RoHS and REACH compliance.
