Overview
The Triad Magnetics A-13J is an audio and signal transformer designed for impedance matching applications. It features a primary resistance of 62 Ohms and a secondary resistance of 70 Ohms. The component operates within a frequency range of 30 Hz to 15 kHz, supporting wide-spectrum signal transmission. Termination is achieved via wire leads, facilitating integration into various circuit boards. This unit belongs to the J series and is packaged in bulk quantities.
Feature Summary
- Impedance matching functionality for audio and signal circuits
- Wide frequency response covering 30 Hz to 15 kHz
- Wire lead termination style for direct circuit integration
Applications
- Audio equipment signal processing
- Telecommunications impedance bridging
- General purpose signal transformation
Procurement Notes
Verify the specific impedance variant required, as the series offers multiple primary impedances including 50, 110, 200, 300, and 600 Ohms. Confirm that the standard 62 Ohm primary and 70 Ohm secondary values align with the design specifications. Ensure wire lead termination compatibility with the target PCB layout before ordering.
Selection Notes
Select this component when precise impedance matching between source and load is critical for audio fidelity or signal integrity. The 30 Hz to 15 kHz bandwidth suits most voice and music applications. Consider the physical dimensions and wire lead length during mechanical design to ensure proper fit within the enclosure.
Part Context
The A-13J is part of Triad Magnetics' J series of audio transformers. These components are engineered for reliable performance in consumer and industrial audio systems. The series provides standardized impedance ratios to simplify circuit design for manufacturers requiring consistent signal transfer characteristics across different product lines.
Replacement Considerations
Check datasheets for other J series variants with different primary impedances if the 62 Ohm value does not match the system requirements. Verify that alternative suppliers offer comparable frequency responses and DCR specifications to maintain signal quality.
