160H20

Overview

The Hammond Manufacturing 160H20 is a low voltage power transformer designed for PCB mounting. It features dual primary windings supporting 115 VAC and 230 VAC inputs, with a secondary output of 20 VAC center-tapped at 1.2 A. The unit has a 24 VA power rating and operates at 50 Hz or 60 Hz. Physical dimensions are 2.25 inches in length, 1.63 inches in width, and 1.38 inches in height. It utilizes solder pin termination and supports an operating temperature range from 0°C to +130°C.

Feature Summary

• Dual primary winding configuration allows flexible connection to either 115 VAC or 230 VAC supply lines.
• Center-tapped secondary winding provides balanced voltage distribution for rectification circuits.
• Through-hole solder pin termination ensures secure mechanical and electrical attachment to printed circuit boards.

Applications

• Low voltage power supplies requiring isolated AC input
• Control transformers for industrial equipment
• Signal isolation in electronic test instruments

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm terminal type and insulation class. Ensure the selected variant matches the required voltage rating and physical footprint for the target PCB layout. Confirm RoHS compliance status if restricted substances are mandated by the end product specifications.

Selection Notes

Select this component when a compact board-mount solution is required for stepping down standard line voltages to a low voltage level. The dual primary design simplifies global deployment without changing hardware. Verify that the 24 VA rating meets the peak load requirements of the downstream circuitry while maintaining thermal stability within the specified operating temperature range.

Part Context

This transformer belongs to the Hammond 160 series, which focuses on low voltage applications for general-purpose electronics. The series offers various power ratings and voltage configurations tailored for PCB integration. The 160H20 specifically addresses needs for moderate current outputs with center-tapped secondary requirements.

Replacement Considerations

Consult official Hammond Manufacturing cross-reference documentation for verified substitute part numbers. Do not assume functional equivalence based solely on similar electrical ratings from other manufacturers without verifying pinout compatibility and enclosure dimensions.
