164F12

Overview

The Hammond Manufacturing 164F12 is a low-voltage power transformer designed for printed circuit board mounting. It features a single primary winding rated at 115 VAC and a dual secondary configuration providing 12.6 VAC center-tapped output. The unit has a power rating of 6 VA, with a secondary current capacity of 0.5 A per winding or 1 A in parallel mode. It utilizes through-hole solder pin termination and operates within a temperature range of 0°C to +130°C. The physical dimensions are 1.63 inches in length, 1.31 inches in width, and 1.31 inches in height.

Feature Summary

• Low profile design optimized for PCB integration
• Dual secondary windings allowing series or parallel connection
• Through-hole solder pin termination for secure mounting

Applications

• Low voltage AC power supply circuits
• Electronic control systems requiring isolated power
• Industrial instrumentation power distribution

Procurement Notes

Verify the specific secondary configuration requirements against the datasheet before procurement. Confirm that the 115 VAC primary input matches the target system voltage. Ensure the PCB layout accommodates the specified lead spacing and physical footprint. Check compliance with local safety regulations regarding isolation barriers and thermal management for the operating temperature range.

Selection Notes

Select this component when a compact, low-voltage transformer is required for direct board mounting. Consider the 6 VA power limit and the ability to configure secondaries in series for higher voltage or parallel for higher current. Evaluate the thermal performance relative to the enclosure environment, as the maximum operating temperature is 130°C. Compare against other models in the 164 series if different voltage ratings or form factors are needed.

Part Context

This transformer belongs to the Hammond 164 series, which specializes in low-profile, low-voltage power transformers for PCB applications. The series offers various voltage configurations while maintaining a consistent mechanical footprint for design flexibility. Hammond Manufacturing produces these components for industrial and commercial electronic equipment requiring reliable isolated power conversion.

Replacement Considerations

Direct substitutes include other Hammond 164 series variants such as 164E20 or 164F48, provided the voltage and current specifications align with the application requirements. Cross-referencing with other manufacturers requires verifying identical electrical parameters, pinout compatibility, and thermal characteristics.
