167L44

Overview

The Hammond Manufacturing 167L44 is a laminated core power transformer designed for chassis mounting. It features a single primary winding rated at 115V and a single secondary winding providing 44VCT (center-tapped) at 2A, resulting in an 88VA maximum power rating. The unit utilizes wire lead termination and measures 63.50mm in length by 76.20mm in width, with a maximum installed height of 77.72mm. It offers 2000Vrms isolation voltage and operates within a temperature range of 0°C to +130°C at 50/60 Hz frequencies.

Feature Summary

• Center-tapped secondary winding configuration for rectification applications
• High thermal tolerance supporting operation up to +130°C
• Robust 2000Vrms electrical isolation between windings
• Laminated core construction for efficient low-voltage power transformation

Applications

• Low voltage filament heating circuits
• Rectifier power supply stages requiring center-tapped input
• Industrial control panel power distribution
• Chassis-mounted electronic equipment power conversion

Procurement Notes

Verify the specific ordering suffix to confirm terminal type and voltage ratings, as variations exist within the 167 series. Confirm RoHS compliance status for environmental regulations. Ensure mechanical dimensions align with available chassis space. Check moisture sensitivity level requirements if storage conditions are critical. Validate that the 115V primary matches the local mains frequency and voltage standards.

Selection Notes

Select this component when a center-tapped secondary is required for full-wave or bridge rectifier configurations. The 88VA rating suits moderate current loads up to 2A. Consider the physical footprint and wire lead termination style for PCB or direct wiring integration. Evaluate the high operating temperature limit for enclosed environments. Compare against similar models like the 167P18 if different voltage or current specifications are needed.

Part Context

Part of the Hammond 167 series of industrial power transformers. This series includes various voltage and wattage combinations tailored for chassis mounting. The 167L44 specifically addresses low-voltage, center-tapped applications. It shares design characteristics with other 167 models but differs in electrical output parameters. The series is widely used in general-purpose industrial electronics.

Replacement Considerations

The 167P18 is a related model in the same series but provides different voltage and current ratings (18VCT at 5A). Verify that the electrical requirements of the circuit match the replacement's output capabilities. Ensure mechanical compatibility regarding mounting holes and overall dimensions. Confirm that the replacement maintains the necessary isolation voltage and thermal performance.
