166J44

Overview

The Hammond Manufacturing 166J44 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 at 1A, delivering a maximum power of 44VA. The unit includes center tap functionality on the secondary side and offers 2000Vrms isolation voltage. Physical dimensions are 93.73mm in length, 50.80mm in width, with a maximum installation height of 58.67mm. The component weighs 771.1g and utilizes wire lead termination.

Feature Summary

• Chassis mount design with wire lead terminations
• Laminated core construction for low voltage applications
• Single primary and single secondary winding configuration
• Center tap available on the secondary output

Applications

• Industrial control panel power supplies
• Low voltage filament heating circuits
• Equipment requiring isolated AC power conversion
• Chassis-mounted electronic assemblies

Procurement Notes

Verify that the specific order matches the 166J44 part number to ensure correct voltage ratings and physical dimensions. Confirm that the application environment supports chassis mounting and wire lead connections. Check for compliance requirements such as RoHS status if applicable to the final product assembly. Ensure the primary voltage input aligns with the 115V specification before integration.

Selection Notes

Select this transformer when a 44VA capacity is sufficient for the load requirements. The 115V primary rating must match the available supply voltage. Consider the physical footprint of 93.73mm by 50.80mm for enclosure space planning. The 2000Vrms isolation rating provides safety separation between primary and secondary circuits. Verify that the 1A secondary current rating meets the peak demand of the connected components.

Part Context

This component belongs to the Hammond Manufacturing 166 series of power transformers. The series offers various power ratings and voltage configurations for industrial use. The 166J44 specifically addresses needs for moderate power conversion with center-tapped outputs. It is part of a broader range of chassis-mountable magnetic components designed for reliability in controlled environments.

Replacement Considerations

Cross-reference with other Hammond 166 series models for different VA ratings or voltage configurations. Verify compatibility with existing wiring harnesses due to wire lead termination style. Ensure replacement units maintain the same 2000Vrms isolation and physical mounting dimensions.
