160D12

Overview

The Hammond Manufacturing 160D12 is a low-voltage power transformer designed for PCB mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50 Hz or 60 Hz frequencies. The secondary output provides 12.6 VAC center-tapped configuration with a maximum current of 90 mA, delivering a total power rating of 1.1 VA. Constructed for through-hole installation via solder pins, the unit measures 1.38 inches in length, 1.13 inches in width, and 1.31 inches in height. It operates within a temperature range of 0°C to +130°C.

Feature Summary

• Dual primary winding capability supporting both 115 VAC and 230 VAC input voltages
• Center-tapped secondary output providing balanced voltage distribution
• Low-profile design optimized for direct printed circuit board mounting

Applications

• Low-power electronic control circuits requiring isolated AC supply
• Industrial equipment utilizing standard line voltages for signal processing
• Consumer electronics devices needing compact step-down transformation

Procurement Notes

Verify that the specific order matches the 160D12 designation to ensure correct secondary voltage and current ratings. Confirm that the application environment remains within the specified operating temperature limits of zero to one hundred thirty degrees Celsius. Ensure the PCB layout accommodates the through-hole pin spacing and physical dimensions provided in the official datasheet to guarantee proper mechanical fit and electrical connectivity.

Selection Notes

Select this component when a compact, low-power transformer is required for direct board integration. The dual primary feature allows flexibility for global voltage standards without changing hardware. Consider the 1.1 VA power limit and 90 mA current capacity to ensure the load does not exceed specifications. The center-tapped output is suitable for applications requiring symmetrical voltage rails or specific rectification topologies.
