Overview
The Hammond Manufacturing 125DSE is a general-purpose audio transformer designed for universal applications. It features a single-ended output configuration with a primary impedance of 2,500/5,000/10,000 ohms and secondary options of 4, 8, 16, or 32 ohms. The unit supports an audio power rating of 10 watts and operates within a frequency range of 100 Hz to 15 kHz. Key electrical specifications include an inductance of 4.48 H and a maximum DC current of 70 mA. The component utilizes chassis mounting and measures 4 inches in length, 2.10 inches in width, and 2.63 inches in height.
Feature Summary
- Single-ended output design suitable for universal audio signal transformation
- Multi-tap primary winding supporting multiple impedance configurations
- Chassis mounting construction for secure installation
Applications
- Audio power amplifier output stages
- Signal isolation in audio processing circuits
- Impedance matching between audio components
Procurement Notes
Verify the specific primary and secondary impedance requirements against the application circuit before ordering. Confirm that the 10W power rating and 70mA DC current limits align with system operational parameters. Ensure chassis mounting provisions are available in the enclosure design. Check RoHS compliance status if required by project specifications.
Selection Notes
Select this model when a single-ended output transformer is required for audio frequencies between 100 Hz and 15 kHz. Consider the 10W power handling capacity and 4.48H inductance for appropriate signal fidelity. Evaluate the available primary and secondary impedance combinations to match source and load requirements. Compare physical dimensions against available chassis space.
Part Context
The 125DSE belongs to Hammond Manufacturing's line of audio and signal transformers. It is categorized as a general-purpose device intended for versatile audio applications. The product series includes variants with different power ratings and impedance configurations to suit various audio system designs.
Replacement Considerations
The 125FSE serves as a higher-power alternative with 20W rating and 90mA capability. The 125GSE offers 25W power handling and 100mA current capacity. These models share similar form factors but differ in electrical performance limits.
