A-10J

Overview

The Triad Magnetics A-10J is an audio transformer designed for impedance matching in professional sound systems. It features a 600CT primary winding and a 150 ohm secondary, providing a 1:10.5 turns ratio. The unit supports a maximum power handling of 1mW and operates within a frequency range of 30Hz to 15kHz with a ±3dB response tolerance.

Feature Summary

• Provides precise impedance transformation between balanced line/microphone sources and grid loads
• Ensures signal integrity across the full audible spectrum with controlled frequency response
• Supports low-power audio applications requiring specific voltage and current matching

Applications

• Professional audio system interconnections
• Microphone to line-level signal conversion
• Impedance bridging in broadcast equipment

Procurement Notes

Verify the specific manufacturing date code against project requirements to ensure component freshness. Confirm that the physical dimensions and mounting style match the existing chassis design. Ensure the 1mW power rating aligns with the signal levels present in the target circuit to prevent saturation or distortion during operation.

Selection Notes

Select this component when a 600 ohm to 150 ohm impedance match is required for low-level audio signals. Consider the ±3dB frequency response limits for high-fidelity applications. Evaluate the mechanical size constraints before finalizing the design to ensure proper fit within the enclosure.

Part Context

This component belongs to Triad Magnetics' audio transformer lineup, specialized for signal conditioning rather than power delivery. It serves as a passive interface device to maintain signal quality across different stages of an audio chain without active amplification.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific impedance ratio and form factor.
