166F20

Overview

The Hammond Manufacturing 166F20 is a low voltage power transformer designed for chassis mounting. It features a laminated core construction with a single primary winding rated for 115 VAC at 60 Hz and a single secondary winding providing 20 VAC center-tapped output. The unit has a power rating of 6 VA and supports a maximum secondary current of 300 mA. Physical dimensions are approximately 71.37 mm in length, 38.1 mm in width, and 42.93 mm in height. It utilizes wire leads for termination and operates within a temperature range of 0°C to +130°C.

Feature Summary

• Laminated core design for efficient power transformation
• Single primary and single secondary winding configuration
• Center-tapped secondary output capability
• Chassis mount installation style with wire lead terminations

Applications

• Industrial control systems requiring low voltage power
• Filament power supply applications
• General purpose low voltage AC power conversion

Procurement Notes

Verify the specific datasheet version and physical terminal configuration before integration. Confirm that the 115V 60Hz primary specification aligns with your local mains frequency and voltage standards. Ensure chassis mounting provisions accommodate the specified dimensional envelope and thermal requirements for continuous operation.

Selection Notes

Select this component when a compact, low-voltage transformer with center-tapped output is required for chassis-mounted industrial applications. Consider the 6 VA power limit and 300 mA current capacity against load demands. Verify compatibility with existing wiring harnesses due to the wire lead termination style rather than PCB pins.

Part Context

This part belongs to the Hammond 166 series of industrial control transformers. These units are characterized by their robust laminated core construction and standardized chassis mounting footprints. The series offers various voltage and wattage combinations tailored for general industrial automation and control panel power distribution needs.

Replacement Considerations

Direct substitutes include other Hammond 166 series variants with matching electrical ratings, such as the 166G16 or 166M2, provided the mechanical mounting and voltage specifications align with the system requirements.
