Overview
The Triad Magnetics HS-4 is a mu-metal shielded audio transformer designed for impedance matching in pro-audio and analog applications. It features a primary impedance range of 62.5, 150, 250, or 600 ohms with a secondary impedance of 117.6 kOhms. The device operates within a frequency range of 20 Hz to 20 kHz and utilizes screw termination for secure mounting. Constructed with a mu-metal case, it provides effective magnetic shielding to minimize interference in demanding signal environments.
Feature Summary
- Mu-metal case construction for superior magnetic shielding
- Multiple primary impedance options for flexible circuit integration
- High secondary impedance for precise voltage step-up
- Screw terminal termination for robust mechanical connection
Applications
- Pro-audio analog applications
- Impedance-matching circuits
- Signal coupling in demanding designs
Procurement Notes
Verify the specific primary impedance variant required (62.5, 150, 250, or 600 Ohms) as the HS-4 series offers multiple configurations. Confirm that the 117.6 kOhm secondary impedance aligns with the target circuit design. Ensure the screw termination style matches the available panel or board mounting infrastructure. Check RoHS compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select the HS-4 when high isolation and low noise are critical due to its mu-metal shielding. Choose this component for applications requiring a fixed high secondary impedance ratio. Consider the physical dimensions and screw mounting requirements during PCB or chassis layout. This transformer is suitable for general-purpose audio signal processing where impedance transformation is necessary.
Part Context
The HS-4 belongs to Triad Magnetics' HS series of audio transformers, which are engineered for durability and precision. These components are specifically marketed for pro-audio and analog applications where signal integrity is paramount. The series emphasizes robust construction to withstand demanding operational environments while maintaining accurate electrical performance across the audible spectrum.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Users must verify compatibility with existing circuit parameters before considering alternative models from other manufacturers.
