The 161D16 is a 1 VA power transformer from the 161 series, designed for vertical PC board mounting. It operates with a single 115V, 60 Hz primary and offers flexible secondary outputs: a 16V center-tapped output at 55mA in a series configuration, or an 8V output at 110mA in a parallel configuration. This model features a concentric wound, split bobbin design which provides low primary-to-secondary coupling, eliminating the need for an electrostatic shield. With a high insulation rating (2,000V RMS Hipot) and Class B insulation, it is suitable for various low-power electronic circuits and power supply applications requiring reliable voltage conversion.
