Overview
The Hammond Manufacturing 162E28-BULK is a low-voltage power transformer designed for PCB mounting. It features a laminated core construction with dual primary windings rated for 115 VAC and 230 VAC operation. The secondary output provides 28 VAC center-tapped configuration at 0.085 A, delivering a total power rating of 2.4 VA. The unit utilizes through-hole solder pin termination for secure board integration. Physical dimensions are approximately 34.93 mm in length, 28.58 mm in width, and 17.78 mm in height, weighing 0.11 kg.
Feature Summary
- Dual primary winding capability supports both 115 VAC and 230 VAC input voltages for global compatibility
- Low-profile design facilitates compact integration into space-constrained printed circuit board assemblies
- Center-tapped secondary output enables flexible rectification and signal processing applications
Applications
- Low voltage power supply circuits requiring isolated AC conversion
- Control panel transformers for industrial instrumentation
- Audio equipment power stages utilizing center-tapped configurations
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm bulk packaging status versus standard retail packaging. Ensure the part number matches the exact electrical specifications required for the target application. Cross-reference the datasheet for any recent revisions that may affect physical dimensions or terminal configurations before finalizing procurement orders.
Selection Notes
Select this component when a low-power, center-tapped transformer is needed for direct PCB mounting. The dual primary winding allows flexibility in regions with different mains voltages without changing hardware. Consider the 2.4 VA power limit and physical footprint constraints relative to other components on the board layout during the design phase.
Part Context
This model belongs to the Hammond 162 series of low-voltage power transformers. The series is characterized by laminated core construction and through-hole mounting options suitable for various electronic enclosures. The 162E28 variant specifically targets applications requiring 28 VAC center-tapped output from standard line voltages.
Replacement Considerations
Consult official Hammond Manufacturing substitution guides for verified equivalent part numbers. Generic replacements must match the 2.4 VA rating, 28 VAC CT secondary, and 115/230 VAC primary specifications while maintaining compatible physical mounting dimensions.
