HS-25

Overview

The Triad Magnetics HS-25 is a general-purpose audio transformer designed for impedance matching in pro-audio analog applications. It features a primary impedance of 15k ohms and a secondary impedance of 111k ohms, with a turns ratio of 1:2.72. The component operates within a frequency range of 20Hz to 20kHz and supports a signal level of 25dBu. It utilizes wire lead termination and is intended for chassis mounting. The physical dimensions are 1.750 inches in length, 1.200 inches in width, and a maximum height of 2.500 inches.

Feature Summary

Provides impedance matching between 15k ohm primary and 111k ohm secondary circuits
Designed for professional audio and analog signal applications
Supports wideband frequency response from 20Hz to 20kHz

Applications

Pro-audio analog circuit interfacing
Impedance matching for audio signal paths
Chassis-mounted audio equipment integration

Procurement Notes

Verify the specific datasheet version and electrical tolerances against the manufacturer's official documentation before integration. Confirm that the chassis mounting style and wire lead termination align with the target PCB or panel layout requirements. Ensure the operating environment remains within standard industrial temperature limits as defined in the product specifications.

Selection Notes

Select this component when a fixed 1:2.72 turns ratio is required to match 15k ohm sources to 111k ohm loads. The chassis mount form factor necessitates available panel space for the specified footprint. Consider the wire lead termination method for assembly compatibility compared to through-hole or surface-mount alternatives.

Part Context

The HS-25 belongs to the HS series of impedance-matching transformers manufactured by Triad Magnetics. This series targets professional audio and analog applications requiring reliable signal transfer between stages with differing impedances. The component serves as a passive interface element rather than an active amplification stage.
