Audio Transformers datasheet and documents for A-58J
Audio Transformers Overview
The Triad Magnetics A-58J is a J Series audio transformer designed for impedance matching applications. It features a primary impedance of 10k Ohms and 2.5k/2.5k Ohms, with secondary impedances of 2k Ohms and 500/500 Ohms. The component has a turns ratio of 2.24:1 and operates within a frequency range of 30Hz to 15kHz. It supports a power rating of 100 mW and includes a primary DC resistance of 1 kOhm. The unit utilizes chassis mounting.
Audio Transformers Feature Summary
- Provides impedance matching between high and low impedance circuits
- Supports dual secondary winding configurations for flexible circuit integration
- Designed for audio signal transmission within specified frequency ranges
Audio Transformers Applications
- Audio equipment interconnection
- Impedance bridging in signal processing chains
- Chassis-mounted audio interface modules
Audio Transformers Procurement Notes
Verify the specific impedance configuration required for your application, as the A-58J offers multiple primary and secondary options. Confirm that the chassis mount style aligns with your enclosure design. Ensure the frequency response meets your audio bandwidth requirements. Check for any mechanical dimension constraints before finalizing the order.
Audio Transformers Selection Notes
Select this component when a fixed 2.24:1 turns ratio is necessary for specific impedance transformation. Consider the 100 mW power handling limit for signal levels. Evaluate the 30Hz to 15kHz bandwidth against your system's audio needs. Compare physical dimensions and mounting requirements with alternative surface-mount or PCB-mount transformers if space is constrained.
Audio Transformers Part Context
The A-58J belongs to the Triad Magnetics J Series, which focuses on audio transformers. This series typically provides robust performance for general audio applications. The model is distinct from other Triad products by its specific impedance ratios and chassis mount form factor, differentiating it from smaller PCB-mounted variants.
Audio Transformers Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing circuit designs if sourcing alternatives.
