167G100

Overview

The Hammond Manufacturing 167G100 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 100V at 500mA with a center tap. The unit delivers a maximum power of 50VA and offers 2000Vrms isolation voltage. Physical dimensions are 55.63mm in length, 66.80mm in width, and up to 66.80mm in height. It utilizes wire leads for termination and weighs approximately 861.8g.

Feature Summary

• Includes a center tap on the secondary winding for load balancing and connection flexibility.
• Provides high isolation voltage capability of 2000Vrms between windings.
• Constructed with a laminated core design for efficient power transformation.

Applications

• Chassis-mounted electronic equipment requiring isolated low-voltage AC power
• Industrial control systems utilizing standard 115V input sources
• Audio or signal processing circuits needing balanced center-tapped inputs

Procurement Notes

Verify the specific voltage configuration (115V primary, 100VCT secondary) matches your circuit requirements before ordering. Confirm that the chassis mounting style and wire lead termination are compatible with your assembly process. Check RoHS compliance status if environmental regulations apply to your project. Ensure physical dimensions fit within the designated enclosure space.

Selection Notes

Select this model when a 50VA capacity is sufficient for the load. The 100VCT secondary output is specific; ensure it aligns with downstream rectification or regulation stages. Consider the weight and size constraints for the installation environment. Compare against other series members if different voltage ratios or power ratings are needed.

Part Context

This component belongs to the Hammond 167 series of enclosed chassis mount transformers. The series offers various power ratings and voltage configurations. The 167G100 specifically addresses applications requiring a higher secondary voltage compared to lower-voltage variants like the 167S6 or 167X5. It shares common mounting and construction characteristics with other units in the family.

Replacement Considerations

Direct substitutes must match the 50VA rating, 115V primary, and 100VCT secondary specifications. Verify identical mounting hole patterns and terminal types. Cross-reference part numbers such as HM4457-ND for distributor-specific equivalents. Ensure replacement units maintain the same isolation voltage and core type.
