162J48

Overview

The Hammond Manufacturing 162J48 is a low-voltage power transformer designed for PCB mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation, providing versatile input compatibility. The secondary output delivers 48 VAC center-tapped voltage with a current rating of 750 mA, resulting in a total power capacity of 36 VA. Constructed with a laminated core, this through-hole component measures 2.63 inches in length, 2.19 inches in width, and 1.56 inches in height. It operates within a temperature range of 0°C to +130°C and utilizes solder pin termination.

Feature Summary

• Dual primary winding configuration supports both 115 VAC and 230 VAC input voltages for flexible deployment.
• Low-profile design facilitates compact integration into printed circuit board assemblies.
• Center-tapped secondary output provides balanced 48 VAC distribution at specified current ratings.

Applications

• Industrial control panel power supplies
• Electronic equipment requiring isolated AC power conversion
• Low-voltage signal processing circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct electrical characteristics. Confirm that the required voltage and current ratings align with the system design before procurement. Check RoHS compliance status as indicated in the product documentation. Ensure the through-hole package dimensions fit the intended PCB layout constraints.

Selection Notes

Select this model when a 36 VA transformer is required for 115/230 VAC input applications. The 48 VAC center-tapped output suits circuits needing symmetrical voltage rails. Consider the physical dimensions and through-hole mounting style for mechanical integration. Evaluate the operating temperature range to ensure suitability for the environmental conditions of the target application.

Part Context

This component belongs to the Hammond 162 series of low-voltage power transformers. The series is characterized by low-profile construction suitable for PCB mounting. The 162J48 variant specifically offers higher power capacity compared to lower-rated models in the same family, utilizing dual secondary windings for flexible output configurations.

Replacement Considerations

The Hammond 162H48 serves as a related alternative within the same series but differs in power rating and current capacity. Verify that the substitute part meets or exceeds the required 36 VA and 750 mA specifications. Ensure the replacement maintains compatible primary and secondary voltage ratings for direct interchangeability.
