162H48

Overview

The Hammond Manufacturing 162H48 is a low-voltage PCB mount power transformer designed for through-hole installation. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50/60 Hz, providing versatile input compatibility. The secondary output delivers 48 VAC center-tapped configuration with a current rating of 0.4 A, resulting in a total power capacity of 20 VA. Constructed with dual secondary windings, the unit measures 2.25 inches in length, 1.88 inches in width, and 1.44 inches in height. It operates within a temperature range of 0°C to +130°C and utilizes solder pin termination for secure board attachment.

Feature Summary

• Dual primary winding design supports both 115V and 230V AC input configurations
• Low-profile construction optimized for direct PCB mounting applications
• Center-tapped secondary output provides balanced voltage distribution
• Through-hole solder pin termination ensures stable mechanical connection

Applications

• Low voltage electronic circuit power supplies
• Industrial control panel transformers
• Consumer electronics internal power conversion
• Signal processing equipment isolation stages

Procurement Notes

Verify that the specific order matches the 162H48 part number exactly, as Hammond offers multiple variants within the 162 series with differing voltages and wattage ratings. Confirm that the required input voltage matches the dual primary specification of 115V or 230V AC. Ensure the PCB layout accommodates the through-hole pin spacing and physical dimensions of 2.25 x 1.88 x 1.44 inches. Check that the application load does not exceed the 20 VA rating or 0.4 A secondary current limit to prevent thermal overload.

Selection Notes

Select this component when a 48V center-tapped output is required from standard 115V or 230V mains sources. The 20 VA rating suits moderate power demands compared to lower-capacity models like the 164G48. Consider the 162 series form factor if higher power density is needed than the smaller 164 series allows. Verify that the operating temperature range up to 130°C meets the environmental requirements of the target enclosure. Ensure the dual secondary winding configuration aligns with the circuit topology needs.

Part Context

The 162H48 belongs to the Hammond 162 series of low-voltage PCB mount transformers. This series is characterized by laminated core construction and through-hole mounting styles. It shares the general physical footprint characteristics with other 162 series units but differs in electrical specifications such as the 161H40 which offers 40V CT output. The series is designed for reliable AC-to-DC power supply front ends in various electronic assemblies.
