160D40

Overview

The Hammond Manufacturing 160D40 is a low voltage power transformer designed for printed circuit board (PCB) mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50 Hz or 60 Hz frequencies. The secondary output provides 40 VAC center-tapped configuration with a current rating of 20 mA, delivering a total power capacity of 1 VA. The unit utilizes solder pin termination for secure electrical connections and operates within a temperature range of 0°C to +130°C.

Feature Summary

• Dual primary winding design supports versatile input voltage requirements
• Center-tapped secondary output enables specific rectification configurations
• Solder pin termination ensures stable PCB integration

Applications

• Low voltage electronic circuit power supplies
• Industrial control panel instrumentation
• Consumer electronics internal power regulation

Procurement Notes

Verify the exact secondary specifications against official datasheets prior to procurement. Confirm that the 40VCT @ 20mA rating aligns with your circuit design requirements. Ensure compatibility with standard through-hole assembly processes. Check for RoHS compliance status if required by your manufacturing standards. Validate physical dimensions against your PCB layout constraints.

Selection Notes

Select this component when a compact, low-power transformer is needed for direct PCB integration. The dual primary winding allows flexibility for different regional input voltages without changing hardware. Consider the thermal limits and ensure adequate ventilation for operation near the maximum temperature rating. Verify that the 1 VA power budget meets the load requirements of the downstream circuitry.

Part Context

This part belongs to the Hammond 160 series of low voltage power transformers. These components are engineered for general-purpose applications requiring isolated AC-to-AC conversion. The series offers various voltage and current combinations to suit diverse electronic design needs while maintaining a standardized footprint for easy substitution within compatible designs.

Replacement Considerations

Consult official Hammond Manufacturing documentation for verified substitute part numbers. Cross-reference secondary voltage and current ratings carefully to ensure functional equivalence. Verify that alternative components match the physical mounting style and terminal type.
