Overview
The Hammond Manufacturing 164G20 is a low voltage power transformer designed for PCB mounting. It features a laminated core construction and a low profile form factor within the 162-164 series. The unit operates with a single primary winding rated for 115V input at 50/60Hz. The secondary configuration provides dual windings, allowing for parallel connection to deliver 10V at 1.2A or series connection to provide 20V center-tapped output at 600mA. This component is suitable for applications requiring compact power conversion.
Feature Summary
- Low profile design optimized for printed circuit board mounting
- Laminated core construction for efficient power transformation
- Dual secondary windings offering flexible parallel or series connectivity options
Applications
- Industrial control systems requiring low voltage AC power
- Electronic instrumentation equipment
- Consumer electronics utilizing PCB-based power supplies
Procurement Notes
Verify the specific datasheet version to confirm electrical tolerances and insulation ratings prior to integration. Ensure that the selected mounting method aligns with the mechanical constraints of the target PCB layout. Confirm that the thermal dissipation characteristics meet the operational requirements of the final assembly environment.
Selection Notes
Select this model when a compact, through-hole mounted transformer is required for 115V primary applications. Choose the parallel secondary configuration for higher current needs or the series configuration for higher voltage outputs. Evaluate the physical dimensions against available board space to ensure proper fitment alongside other components.
Part Context
This component belongs to the Hammond 162-164 series, which encompasses low voltage PCB mount transformers ranging from 1.1 VA to 36 VA. The series is characterized by its standardized footprint and low profile, facilitating easy integration into dense electronic assemblies where vertical clearance is limited.
Replacement Considerations
Consult official cross-reference lists for direct equivalents. Verify that any substitute part matches the primary voltage, frequency, and secondary voltage/current specifications exactly to maintain system performance.
