160D56

Overview

The Hammond Manufacturing 160D56 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. The secondary output provides 56 VAC center-tapped configuration with a maximum current of 15 mA, delivering a total power rating of 1 VA. Constructed with solder pin termination for through-hole installation, the unit measures 1.38 inches in length, 1 inch in width, and 0.83 inches in height. It operates within a temperature range of 0°C to +130°C.

Feature Summary

• Dual primary winding capability allows flexible connection to either 115 VAC or 230 VAC input sources.
• Center-tapped secondary winding provides symmetrical voltage distribution for specific circuit requirements.
• Through-hole solder pin termination ensures secure mechanical and electrical attachment to printed circuit boards.

Applications

• Low voltage signal processing circuits requiring isolated power supplies
• Control panels utilizing standard AC line voltages

Procurement Notes

Verify the specific manufacturing date code against current RoHS compliance requirements before integration. Confirm that the 1 VA power rating aligns with the thermal management capabilities of the target PCB layout. Ensure the physical dimensions fit within the designated enclosure space without obstructing adjacent components. Validate that the operating temperature range meets the environmental conditions of the final assembly site.

Selection Notes

Choose this component when a small form factor transformer is required for direct board mounting. Select this model if the application demands isolation between primary and secondary circuits. Consider this part for designs where dual primary voltage flexibility simplifies global deployment. Evaluate the 15 mA current limit to ensure it satisfies the load requirements of the downstream electronics without exceeding thermal limits.
