164H48

Overview

The Hammond Manufacturing 164H48 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 48 VAC center-tapped output. The unit has a power rating of 20 VA with a secondary current capacity of 400 mA. 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.

Feature Summary

• Low profile design suitable for PCB mounting applications
• Dual secondary winding configuration for flexible circuit integration
• Through-hole solder pin termination for secure board attachment

Applications

• Industrial control panels requiring low voltage power distribution
• Electronic equipment utilizing center-tapped rectifier circuits
• Instrumentation systems needing isolated AC power sources

Procurement Notes

Verify the specific voltage configuration and physical footprint against the target PCB layout before procurement. Confirm that the 20 VA rating and 400 mA current capacity meet the load requirements of the intended application. Ensure compatibility with the manufacturing process for through-hole soldering to guarantee reliable electrical connections and mechanical stability during operation.

Selection Notes

Select this component when a compact, low-voltage transformer is required for PCB integration. The 164H48 offers a balance of power density and physical size compared to larger chassis-mounted alternatives. Consider the center-tapped secondary specification if the downstream circuitry requires split-rail or full-wave rectification capabilities from a single transformer source.

Part Context

This part belongs to the Hammond 164 series of low voltage PCB mount transformers. These components are characterized by their laminated core construction and low-profile form factor. The series provides various voltage and wattage options to support diverse electronic design needs while maintaining standard through-hole mounting compatibility.

Replacement Considerations

Direct substitutes within the same series include the 164G48 (12 VA) and 162H48 (20 VA, dual primary). Verify that alternative models match the required 48 VAC CT output and 400 mA current rating. Check dimensional constraints as different variants may have varying height or footprint specifications.
