166G10

Overview

The Hammond Manufacturing 166G10 is a low voltage industrial power transformer designed for chassis mounting. 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 5 VA with a maximum secondary current of 500 mA. Physical dimensions are approximately 71.4 mm in length, 38.1 mm in width, and 42.9 mm in height. It utilizes wire leads for termination and operates within a temperature range of 0°C to +130°C at 50/60 Hz.

Feature Summary

• Chassis mount design with horizontal channel bracket for two-hole or open horizontal four-hole installation
• Single primary and single secondary winding configuration for standard control applications
• Center-tapped secondary output capability for rectification circuits
• Robust construction suitable for industrial environments up to +130°C

Applications

• Industrial control panel power supply
• Low voltage signal processing circuits
• Equipment requiring isolated 10V AC power
• Rectifier input stages for DC conversion

Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm exact lead times and packaging configurations. Ensure the ordering part number matches the required voltage and current specifications for the target application. Confirm compliance requirements such as RoHS status prior to final procurement decisions.

Selection Notes

Select this component when a compact, chassis-mountable transformer is needed for 115V primary systems. The 5 VA rating suits low-power control logic or indicator circuits. Consider the physical footprint and wire lead length during PCB or panel layout planning. Verify that the center-tapped requirement aligns with the downstream circuit topology.

Part Context

This model belongs to the Hammond 166 series of industrial control transformers. The series offers various voltage and wattage combinations while maintaining consistent chassis-mount form factors. These units are engineered for reliability in continuous duty industrial settings, providing electrical isolation between primary and secondary circuits.

Replacement Considerations

Direct substitutes include other Hammond 166 series variants with matching 5 VA ratings and 10V CT outputs, such as the 166G8 or 166G16 if voltage differences are acceptable. Cross-brand replacements require verification of pinout compatibility, thermal limits, and mechanical mounting hole spacing.
