FH-23377-000

Speakers Overview

The Knowles FH-23377-000 is a balanced armature receiver designed for high-power hearing aid applications. It features a rectangular top-mount package with side porting and an impedance of 1.03 kOhms. The frequency response spans from 200 Hz to 6.3 kHz, providing a medium DC resistance to impedance ratio similar to EF receivers.

Speakers Feature Summary

• Balanced armature technology optimized for high power output
• Rectangular surface mount package with side port configuration
• Medium DC resistance to impedance ratio

Speakers Applications

• High power hearing aids
• Medical audio devices
• Personal sound amplification products

Speakers Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Knowles or authorized distributors before finalizing procurement. Ensure the ordering suffix matches the required packaging format. Confirm that the 1.03 kOhm impedance aligns with your circuit design requirements for optimal performance in hearing aid applications.

Speakers Selection Notes

Select this component when a high-power balanced armature receiver is required within an EF-sized form factor. The 1.03 kOhm impedance and 200 Hz to 6.3 kHz bandwidth suit standard hearing aid signal processing chains. Consider the side-port mounting style for acoustic integration constraints in tight enclosures.

Speakers Part Context

This part belongs to Knowles' TEC Balanced Armature Speaker series, which focuses on delivering high acoustic output in miniature packages. The FH series is engineered specifically for medical audio applications, offering reliability and consistent performance characteristics suitable for implantable or behind-the-ear hearing solutions.

Speakers Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Evaluate other EF-sized balanced armature receivers from Knowles or competitors with matching 1.03 kOhm impedance and similar frequency response curves. Verify mechanical footprint compatibility and acoustic sensitivity levels before substitution.
