166J10

Overview

The Hammond Manufacturing 166J10 is a laminated core power transformer designed for chassis mount applications. It features a single primary winding rated at 115 VAC and a single secondary winding providing 10 VAC center-tapped output. The unit has a power rating of 10 VA with a maximum secondary current of 1 A. Physical dimensions are 71.4 mm in length, 38.1 mm in width, and 35.1 mm in height. It utilizes wire leads for termination and operates within a temperature range of 0°C to +130°C at 50 Hz or 60 Hz frequencies.

Feature Summary

• Chassis mount construction with wire lead terminations
• Single primary and single secondary winding configuration
• Low voltage step-down capability from 115V AC input

Applications

• Industrial control panels requiring low voltage power
• Equipment chassis integration for signal processing circuits
• General purpose power supply transformation in industrial machinery

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to ensure correct voltage and current ratings. Confirm that the chassis mounting style and wire lead termination type match the system requirements. Cross-reference the physical dimensions with the enclosure design to guarantee proper fit. Ensure the operating frequency range aligns with the primary power source specifications before finalizing procurement.

Selection Notes

Select this component when a 10 VA capacity is sufficient for the load requirements. Consider the 115 VAC primary input compatibility with the available power infrastructure. Evaluate the chassis mount constraint against the available installation space. Verify that the center-tapped secondary output meets the circuit design needs. Assess the thermal performance requirements against the specified operating temperature limits.

Part Context

This transformer belongs to the Hammond 166 series, which provides various power ratings for industrial control applications. The series offers different voltage configurations and wattage options to suit diverse equipment needs. The 166J10 specifically addresses applications requiring a 10 VA output with a 10 VAC center-tapped secondary winding. It serves as a standard solution for stepping down line voltage in controlled environments.

Replacement Considerations

Consult the Hammond Manufacturing datasheet for direct cross-references within the 166 series. Verify electrical parameters such as VA rating, voltage, and current against potential substitutes. Ensure mechanical dimensions and mounting styles are compatible with existing installations.
