ED-23145-000

Speakers Overview

The Knowles ED-23145-000 is a balanced armature receiver utilizing magnetic technology. It features a rectangular form factor with dimensions of 6.30mm in length and 4.29mm in width, weighing approximately 0.31 grams. The component operates within a frequency range of 200 Hz to 5 kHz and maintains an impedance of 1.45 kOhms. It achieves a sound pressure level of 104 dBA at a test frequency of 5 kHz. Termination is provided via solder pads for surface mounting.

Speakers Feature Summary

• Balanced armature transducer design for high-fidelity audio reproduction
• Magnetic actuation mechanism integrated into a compact rectangular housing
• Solder pad termination style facilitating direct surface mount integration

Speakers Applications

• In-ear monitor receivers
• Hearing aid acoustic modules
• Compact consumer audio headsets

Speakers Procurement Notes

Verify the specific revision level against project requirements, as documentation indicates Revision C. Confirm that the 1.45 kOhm impedance aligns with the driving circuit's output capabilities. Ensure the solder pad footprint matches the PCB layout exactly, given the precise 6.30mm x 4.29mm dimensions. Validate compliance with relevant environmental standards if required by the final assembly specifications.

Speakers Selection Notes

Select this component when a high-impedance balanced armature receiver is necessary for low-power audio applications. The 1.45 kOhm impedance requires compatible driver circuits compared to lower impedance dynamic speakers. The rectangular package suits tight spatial constraints in wearable or portable devices. Consider the 104 dBA sensitivity for volume requirements without excessive power consumption.

Speakers Part Context

This part belongs to Knowles' line of precision audio receivers designed for miniaturized electronic devices. Balanced armature technology is preferred in hearing aids and premium audio gear for its efficiency and clarity. The ED series typically denotes specific acoustic tuning and mechanical configurations tailored for discrete receiver applications rather than loudspeaker drivers.

Speakers Replacement Considerations

Direct substitutes must match the 1.45 kOhm impedance, 200Hz-5kHz frequency response, and rectangular SMT footprint. Verify that alternative balanced armature receivers provide comparable sound pressure levels to maintain audio performance consistency.
