Audio Transformers datasheet and documents for AEI19-4660
Audio Transformers Overview
The AEI19-4660 is a through-hole audio transformer manufactured by Allied Components International. It features a 1:1 turns ratio with 10k ohm impedance on both primary and secondary windings. The device operates within a frequency range of 300Hz to 3.4kHz. Designed for audio applications, it provides impedance matching capabilities in a standard through-hole package configuration suitable for PCB mounting.
Audio Transformers Feature Summary
- Provides 1:1 turns ratio for signal isolation
- Features matched 10k ohm primary and secondary impedances
- Optimized for audio frequency band operation
Audio Transformers Applications
- Audio signal isolation circuits
- Impedance matching between audio stages
- Balanced/unbalanced audio interface conversion
Audio Transformers Procurement Notes
Verify the manufacturer designation as Allied Components International to distinguish from other vendors using similar part numbers. Confirm the specific impedance value of 10k ohms and the 1:1 ratio match system requirements. Ensure the through-hole package type is compatible with the target PCB layout. Check RoHS compliance status if environmental regulations apply to the final assembly.
Audio Transformers Selection Notes
Select this component when a 10k ohm to 10k ohm audio transformer is required. The 300Hz to 3.4kHz bandwidth suits standard voice and music transmission. Through-hole construction is necessary for mechanical stability or legacy board designs. Verify that the impedance matches the source and load characteristics of the connected audio circuitry to prevent signal degradation.
Audio Transformers Part Context
This component belongs to the EE19 series of high-frequency impedance matching transformers designed specifically for audio applications. The series includes variants with different pinouts or slight parameter variations, but the AEI19-4660 is defined by its 10k ohm impedance and 1:1 ratio. It serves as a passive magnetic coupling element in analog audio signal paths.
