167Q5

Overview

The Hammond Manufacturing 167Q5 is an industrial power transformer designed for chassis mounting. It features a laminated core construction with a single primary winding rated at 115 VAC and a single secondary winding providing 5 VAC center-tapped output. The unit has a power rating of 30 VA, supporting a secondary current of 6 A. Operating within a frequency range of 50 Hz to 60 Hz, it functions reliably between 0°C and +130°C. Physical dimensions are approximately 55.6 mm in length, 66.8 mm in width, and 66.8 mm in height, with wire lead termination.

Feature Summary

• Enclosed chassis mount design for secure installation
• Laminated core construction for efficient voltage transformation
• Single primary and secondary winding configuration
• Low voltage filament application suitability

Applications

• Industrial control panels requiring low voltage power
• Chassis-mounted equipment needing 5V center-tapped supply
• Filament heating circuits in industrial machinery
• General purpose low voltage AC power distribution

Procurement Notes

Verify the specific model suffix and electrical ratings against the official Hammond Manufacturing datasheet before procurement. Confirm that the 115 VAC primary input matches the local supply voltage. Ensure the chassis mounting space accommodates the specified physical dimensions. Check for compliance with regional safety standards required for the final assembly. Validate wire lead gauge and length requirements for the intended circuit layout.

Selection Notes

Select this component when a compact, enclosed transformer is needed for 5V center-tapped applications. Consider the 30 VA power limit to ensure adequate capacity for the load. Evaluate the chassis mounting style against available panel space. Compare thermal performance at maximum operating temperatures if ambient conditions are high. Verify insulation class and safety certifications for the target market.

Part Context

The 167Q5 belongs to the Hammond 167 series of low voltage power transformers. This series offers various power ratings and voltage configurations for industrial use. The 167Q5 specifically addresses needs for small form factor, low voltage power conversion. It complements other models in the series with different VA ratings or secondary voltages.

Replacement Considerations

Direct substitutes may include other Hammond 167 series models with identical 30 VA, 115V primary, and 5VCT secondary specifications. Cross-reference physical dimensions and terminal types to ensure mechanical compatibility. Verify that alternative components meet the same thermal and safety standards.
