HS-52

Overview

The Triad Magnetics HS-52 is a hermetically sealed low-level audio output transformer designed for precision signal transfer. It features a Mu-Metal case construction to ensure magnetic shielding and durability in demanding environments. The unit provides a primary impedance of 20 kohm with a turns ratio of 5.6:1. The secondary side offers multiple impedance options including 62.5 ohm, 150 ohm, 250 ohm, and 600 ohm. It supports a maximum frequency of 20 kHz and operates at a minimum power level of 26 mW, making it suitable for balanced center-tapped applications.

Feature Summary

• Hermetically sealed construction ensures long-term durability and environmental protection
• Mu-Metal case provides effective magnetic shielding for signal integrity
• Balanced center-tapped design facilitates precise audio signal matching
• Multiple secondary impedance configurations support versatile system integration

Applications

• Plate-to-universal line connections in professional audio systems
• Low-level audio output stages requiring high fidelity
• Mixing console input/output interfaces
• Broadcast equipment signal conditioning

Procurement Notes

Verify the specific secondary impedance configuration required for your circuit design, as the HS-52 supports multiple values including 62.5, 150, 250, and 600 ohms. Confirm that the 20 kohm primary impedance aligns with your source device specifications. Ensure the physical dimensions and mounting requirements fit within your enclosure constraints. Check for any specific lead time variations based on current manufacturing schedules before finalizing procurement plans.

Selection Notes

Select the HS-52 when hermetic sealing and superior magnetic shielding are critical for maintaining audio quality in noisy environments. The choice depends on matching the 20 kohm primary impedance to your tube plate or similar high-impedance source. Consider the available secondary impedance options to ensure proper load matching for your downstream components. This component is ideal for applications where size constraints allow for its specific form factor while demanding high reliability.

Part Context

The HS-52 belongs to Triad Magnetics' lineup of specialized audio transformers, distinguished by its robust hermetic sealing and Mu-Metal shielding. Unlike standard open-frame units, this model is engineered for harsh conditions requiring sustained performance. It serves as a bridge between high-impedance vacuum tube plates and lower-impedance universal lines, ensuring minimal signal degradation across the audible spectrum.
