ED-27288-000

Speakers Overview

The Knowles ED-27288-000 is a balanced armature receiver designed for high-power hearing aid applications. It features a side rectangular port and board mount configuration. Key electrical parameters include an impedance of 100 Ohms, a frequency response range of 20 Hz to 30 kHz, and a sound pressure level (SPL) of 104 dBA. The component exhibits a medium direct current resistance (DCR) to impedance ratio, offering performance characteristics similar in size to an EF receiver.

Speakers Feature Summary

• Balanced armature technology optimized for high power output
• Side rectangular port design for specific acoustic integration
• Medium DCR to impedance ratio for efficient signal transfer

Speakers Applications

• High power hearing aids
• Medical audio devices requiring compact receivers
• Assistive listening systems

Speakers Procurement Notes

Verify the specific datasheet version when ordering, as manufacturer documentation may contain updates regarding mechanical dimensions or acoustic tolerances. Confirm RoHS compliance status with the supplier prior to finalizing procurement orders to ensure adherence to environmental regulations applicable in your region.

Speakers Selection Notes

Select this component when a compact receiver with high power handling capabilities is required. The 100 Ohm impedance suits circuits designed for higher voltage drive levels. Ensure the application environment accommodates the physical dimensions of the side-port rectangular form factor.

Speakers Part Context

This part belongs to the Knowles TEC Balanced Armature Speaker series. These components are engineered for critical audio reproduction in small form factors. The ED series typically targets the medical and hearing aid sectors, prioritizing reliability and acoustic precision over general consumer audio specifications.

Speakers Replacement Considerations

No officially confirmed substitute part numbers are available in public documentation. Due to the specific acoustic tuning and balanced armature architecture, direct replacements must be verified against exact impedance and SPL curves by the system designer.
