Overview
The Hammond Manufacturing 162D16 is a low voltage power transformer designed for PCB mounting. It features a laminated core construction and supports dual primary voltages of 115V and 230V. The secondary output provides 16V center-tapped configuration at a maximum current of 70mA, delivering a total power rating of 1.1VA. This component utilizes through-hole termination for secure board integration.
Feature Summary
- Low profile design optimized for printed circuit board mounting
- Dual primary winding capability for 115V and 230V operation
- Laminated core construction for efficient power transfer
Applications
- Low voltage electronic equipment requiring isolated power
- Control panels utilizing PCB-based power distribution
- Industrial instrumentation with specific low voltage requirements
Procurement Notes
Verify the exact secondary configuration matches the application requirement, as the 162D16 specifies a 16V center-tapped output. Confirm that the 1.1VA power rating and 70mA current limit are sufficient for the load. Ensure the PCB footprint accommodates the through-hole pin spacing and physical dimensions of this low-profile unit before ordering.
Selection Notes
Select this model when a compact, low-voltage transformer is needed for direct PCB installation. It is suitable for applications requiring isolation between 115/230V mains and low voltage DC circuits derived from the rectified AC output. Consider the 1.1VA limit to ensure adequate headroom for peak loads without overheating.
Part Context
This component belongs to the Hammond 162-164 series of low voltage PCB mount transformers. These units are characterized by their low profile and laminated core design, intended for space-constrained electronic assemblies requiring reliable AC-to-AC isolation prior to rectification.
Replacement Considerations
The 164D16 is a related part within the same series but may differ in power rating or physical dimensions. Verify compatibility with existing PCB footprints and thermal management requirements when considering substitutes.
