HS-8

Audio Transformers Overview

The Triad Magnetics HS-8 is a hermetically sealed audio transformer designed for professional analog applications. It features a primary impedance of 62.5, 150, 250, and 600 ohms with a secondary impedance of 117.6k ohms. The unit operates within a frequency range of 20Hz to 20kHz and supports a maximum input level of 20dBu. Constructed with welded stainless steel studs and multiple trialloy case interleaves with heavy copper shading rings, it provides up to 95dB shielding. The transformer utilizes a chassis mount installation style with wire lead terminations.

Audio Transformers Procurement Notes

Verify the specific datasheet version to confirm compliance with current MIL-T-27 standards and RoHS3 status. Ensure that the chassis mounting dimensions and wire lead configurations align with the target enclosure design. Confirm that the primary impedance taps match the source circuit requirements before finalizing procurement orders.

Audio Transformers Selection Notes

Select this component when hermetic sealing and superior shielding are critical for signal integrity in noisy environments. The wide primary impedance options allow flexibility in interfacing with various audio sources. Consider the chassis mount requirement and physical size constraints during the initial design phase to ensure proper integration into the final assembly.
