Overview
The Hammond Manufacturing 164H28 is a low voltage power transformer designed for printed circuit board mounting. It features a single primary winding rated for 115 VAC input and a dual secondary winding configuration providing 28 VAC center-tapped output. The unit delivers a power rating of 10 VA with a secondary current capacity of 360 mA. Constructed for through-hole installation, it utilizes solder pin termination. The component operates within a temperature range of 0°C to +130°C and measures 1.44 inches in length, 1.94 inches in width, and 1.69 inches in height.
Feature Summary
- Low profile design optimized for PCB integration
- Dual secondary winding capability for center-tapped applications
- Through-hole solder pin termination for secure board attachment
Applications
- Industrial control panel power supplies
- Electronic instrumentation internal power stages
- Low voltage AC signal conditioning circuits
Procurement Notes
Verify the specific part number suffix against official Hammond Manufacturing documentation to ensure correct voltage and current ratings. Confirm that the package dimensions and pin spacing match the target PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this model when a compact, low-voltage transformer is required for direct PCB mounting. Ensure the application demands a 115V primary input and a 28V CT secondary output. Verify that the 10 VA power rating and 360 mA current limit satisfy the load requirements of the downstream circuitry.
Part Context
This component belongs to the Hammond 164 series of low voltage transformers. These units are characterized by their small footprint and suitability for space-constrained electronic assemblies. The series offers various voltage configurations while maintaining consistent mechanical mounting standards for industrial electronics.
Replacement Considerations
Consult official Hammond Manufacturing cross-reference lists for verified substitutes. Do not assume functional equivalence with generic transformers based solely on similar electrical ratings without verifying physical dimensions and pinout compatibility.
