164H56

Overview

The Hammond Manufacturing 164H56 is a low-voltage power transformer designed for printed circuit board (PCB) mounting. It features a single primary winding rated at 115 VAC and a dual secondary winding configuration providing 56 VAC center-tapped output. The unit has a power rating of 20 VA, with each secondary leg delivering 0.35 A. Constructed as a low-profile component, it utilizes through-hole solder pin termination for secure board attachment. The transformer operates within a temperature range of 0°C to +130°C and measures 1.38 inches in length, 1.13 inches in width, and 1.19 inches in height.

Feature Summary

• Low-profile design optimized for space-constrained PCB applications
• Dual secondary windings enable flexible center-tapped voltage configurations
• Through-hole solder pin termination ensures robust mechanical and electrical connection

Applications

• Industrial control panel power supplies
• Instrumentation equipment internal power conversion
• Consumer electronics requiring isolated low-voltage AC sources

Procurement Notes

Verify the specific manufacturing date code and RoHS compliance status upon order confirmation, as environmental certifications may vary by production batch. Ensure that the receiving facility's handling procedures account for the component's weight and physical dimensions to prevent mechanical stress during installation. Confirm that the intended operating environment remains within the specified thermal limits to maintain performance integrity.

Selection Notes

Select this model when a compact, board-mounted solution is required for stepping down 115 VAC mains voltage to a usable 56 VAC center-tapped level. The 20 VA rating supports moderate current demands typical in control circuits. Consider the physical footprint constraints against the 1.38 x 1.13 inch base area. This component is suitable for designs prioritizing low profile over high-power density.

Part Context

The 164H56 belongs to the Hammond 164 series of low-voltage PCB mount transformers. This series is characterized by its standardized low-profile form factor and through-hole construction. The 164 series provides various voltage and wattage combinations to accommodate different power requirements while maintaining a consistent mounting style and dimensional envelope across the product line.

Replacement Considerations

The Hammond 164E56 serves as a direct substitute within the same series, offering identical physical dimensions and mounting characteristics but with a reduced 2.4 VA power rating and 0.045 A secondary current capacity. Designers must verify that the lower power capability of the 164E56 meets the load requirements before implementing it as a replacement.
