161C16

Overview

The Hammond Manufacturing 161C16 is a low voltage power transformer designed for PCB mounting. It features a single primary winding rated at 115 VAC and dual secondary windings providing a center-tapped output of 16 VAC CT. The unit has a power rating of 0.5 VA, with secondary current ratings of 31.3 mA per leg and 62.5 mA total. Operating within a temperature range of 0°C to +130°C at 60 Hz, it utilizes solder pin termination and meets UL 94 V-2 flammability standards.

Feature Summary

• Dual secondary winding configuration with center tap
• Through-hole solder pin termination for PCB integration
• High thermal stability up to +130°C
• Low voltage operation suitable for sensitive electronics

Applications

• Low power control circuitry
• Signal processing equipment
• Instrumentation systems
• Consumer electronic devices

Procurement Notes

Verify the specific datasheet version for the 161C16 to confirm exact dimensional tolerances and insulation class requirements. Ensure that the receiving facility can handle the specified operating temperature range during storage and installation. Cross-reference the secondary current ratings against the load requirements of the target application to prevent thermal overload.

Selection Notes

Select this component when a compact, low-power transformer is required for direct PCB integration. The 161C16 is appropriate for applications needing a 115V input and a precise 16V center-tapped output. Consider the 0.5 VA power limit and ensure the design accounts for the maximum operating temperature of +130°C to maintain reliability in enclosed spaces.

Part Context

The 161C16 belongs to the Hammond 161 series of low voltage PCB mount transformers. This series is characterized by its small form factor and through-hole construction, making it suitable for space-constrained designs. It shares common design principles with other models in the series, such as the 161H40 and 161G28, differing primarily in voltage and power specifications.

Replacement Considerations

For equivalent performance, consider the Hammond 161E40 or 161G28 if voltage or power requirements differ. Verify that any substitute maintains the same 115V primary rating and center-tapped secondary configuration to ensure compatibility with existing circuit layouts.
