164D16

Overview

The Hammond Manufacturing 164D16 is a low voltage power transformer designed for PCB mounting. It features a single primary winding rated at 115 VAC and a dual secondary winding configuration providing 16 VAC center-tapped output. The unit has a power rating of 1.1 VA with a secondary current capacity of 70 mA. Constructed as a low-profile through-hole component, it measures 1.38 inches in length, 1.13 inches in width, and 1.31 inches in height. The device operates within a temperature range of 0°C to +130°C and utilizes solder pin termination.

Feature Summary

• Low profile design optimized for space-constrained printed circuit board applications
• Dual secondary winding architecture enabling flexible center-tapped circuit configurations
• Through-hole construction with solder pin termination for secure board integration

Applications

• Low voltage power supply circuits for electronic devices
• Control panel power distribution systems
• Instrumentation equipment requiring isolated AC power sources

Procurement Notes

Verify the specific secondary current rating against official datasheets, as some sources cite 45 mA while others indicate 70 mA for this model. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Ensure the selected variant matches the required voltage and physical dimensions for the target application.

Selection Notes

Select this transformer when a compact, low-voltage AC source is required for PCB-based designs. The 1.1 VA rating suits low-power control logic or signal processing stages. Consider the 1.31-inch height constraint for enclosure clearance. Verify thermal requirements against the +130°C maximum operating temperature limit for the intended environment.

Part Context

This component belongs to the Hammond 164 series of low voltage PCB mount transformers. The series offers various voltage and wattage combinations tailored for industrial and commercial electronics. The 164D16 specifically addresses needs for 16V center-tapped outputs in a standardized low-profile footprint compatible with standard through-hole assembly processes.

Replacement Considerations

The Hammond 164D24 serves as a functional substitute offering identical physical dimensions and primary voltage but provides a 24V center-tapped output instead of 16V. Ensure the load current requirements do not exceed the 70 mA limit of the 164D16 when considering alternative models within the same series.
