AEI14-4440

Audio Transformers Overview

The AEI14-4440 is a through-hole audio coupling transformer manufactured by Allied Components International. It features a 1:1 turns ratio and a primary impedance of 10 kΩ, with a secondary impedance also rated at 10 kΩ. The component utilizes an EI14 core structure designed for line-level audio signal transmission. It operates without active components or shared ground references, ensuring isolation between circuits. The device complies with RoHS3 environmental standards and is suitable for applications requiring balanced audio interfacing.

Audio Transformers Feature Summary

• Provides galvanic isolation for line-level audio signals
• Features a 1:1 turns ratio for direct signal coupling
• Utilizes an EI14 core structure for compact integration

Audio Transformers Applications

• Line-level audio signal coupling
• Balanced audio interfacing
• Audio circuit isolation

Audio Transformers Procurement Notes

Verify the specific package type and pin configuration against the official datasheet before integration. Confirm that the 10 kΩ impedance rating aligns with the source and load requirements of the target audio circuit. Ensure compliance with RoHS3 regulations if required by the final product specifications. Cross-reference the manufacturer's part number to avoid confusion with similar series components.

Audio Transformers Selection Notes

Select this component when a 1:1 audio transformer with 10 kΩ impedance is required for line-level applications. Consider the EI14 form factor for space-constrained designs. Evaluate the through-hole mounting requirement against available PCB layout options. Ensure the operating frequency range supports the intended audio bandwidth without significant attenuation.

Audio Transformers Part Context

This component belongs to the Allied Components International audio transformer series, specifically designed for coupling applications. It shares the EI14 core designation with other models in the lineup but differs in impedance and winding ratios. The AEI14-4440 is distinct from power transformers due to its focus on signal integrity rather than energy conversion.

Audio Transformers Replacement Considerations

Consult the manufacturer's cross-reference list for verified substitutes. Ensure any replacement maintains the 10 kΩ impedance and 1:1 ratio. Verify mechanical compatibility with the existing PCB footprint.
