164H20

Overview

The Hammond Manufacturing 164H20 is a low voltage power transformer designed for PCB mounting. It features a single primary winding rated at 115 VAC and a dual secondary winding configuration providing 20 VAC center-tapped output. The unit delivers a total power rating of 20 VA with a secondary current capacity of 1 A. Physical dimensions are 2.25 inches in length, 1.88 inches in width, and 1.44 inches in height. It utilizes through-hole solder pin termination and operates within a temperature range of 0°C to +130°C.

Feature Summary

• Low profile design optimized for printed circuit board integration
• Dual secondary winding architecture enabling center-tapped configurations
• Through-hole solder pin termination for secure board attachment

Applications

• Low voltage power supply circuits requiring isolated AC sources
• Electronic equipment utilizing center-tapped rectification topologies
• Industrial control systems needing compact PCB-mounted transformers

Procurement Notes

Verify the specific secondary voltage and current ratings against the application requirements before ordering. Confirm that the physical footprint and lead spacing match the target PCB layout. Ensure the operating environment remains within the specified thermal limits. Check for RoHS compliance documentation if required by project standards. Validate that the single primary input matches the available line voltage.

Selection Notes

Select this component when a 20 VA power rating and 115 VAC primary input are required. Choose the 164H20 over other series members if the specific 20V CT secondary output is necessary. Consider the physical dimensions to ensure adequate clearance on the assembly. Evaluate the through-hole mounting style against surface-mount alternatives if space constraints exist.
