164H12

Overview

The Hammond Manufacturing 164H12 is a low voltage power transformer designed for PCB mounting. It features a single primary winding rated for 115 VAC and dual secondary windings providing 12.6 VAC center-tapped output. The unit has a power rating of 20 VA, with a secondary current capacity of 1.6 A in series configuration or 3.2 A in parallel. It utilizes through-hole solder pin termination and operates within a temperature range of 0°C to +130°C.

Feature Summary

• Low profile design suitable for printed circuit board mounting
• Dual secondary windings allowing flexible series or parallel connection
• Robust construction supporting high operating temperatures up to 130°C

Applications

• Industrial control panels requiring low voltage AC power
• Electronic equipment needing isolated power supply stages
• Automation systems utilizing standard 115VAC input lines

Procurement Notes

Verify the specific secondary configuration requirements (series vs. parallel) against the application circuit before ordering. Confirm that the physical dimensions and lead spacing are compatible with the target PCB layout. Ensure the ambient operating environment does not exceed the maximum rated temperature of 130°C to maintain component longevity and safety compliance.

Selection Notes

Select this model when a 20 VA rating is required from a 115 VAC source. Choose the 164H12 over lower wattage variants if higher current delivery at 12.6 VAC is necessary. Consider the physical size constraints relative to other 164 series transformers to ensure adequate clearance on the assembly board.

Part Context

This component belongs to the Hammond 164 series of low voltage PCB mount transformers. The series offers various power ratings and voltage configurations to support diverse electronic design needs. The 164H12 specifically addresses applications requiring moderate power output with flexible secondary wiring options.

Replacement Considerations

Direct substitutes within the same series include models like 164F120 or 164J16, though these differ significantly in power rating and voltage output. Verify electrical compatibility carefully as no identical 20VA 12.6VCT alternative is explicitly listed in the provided data.
