• Rectangular housing design
• Top port acoustic configuration

Applications

• Hearing aids
• Earwigs
• Bone conduction devices

Procurement Notes

Verify the specific revision code and packaging format against the official Knowles datasheet before ordering. Confirm that the terminal orientation matches the target PCB footprint. Ensure compliance with RoHS directives if required for the final assembly. Check for any recent lifecycle status updates directly from the manufacturer.

Selection Notes

Select this component when a compact, high-output receiver is needed for hearing assistance applications. The 7.2 Ohm impedance suits standard driver circuits. The top port design facilitates direct acoustic coupling to the ear canal or bone conductor interface.

Part Context

This part belongs to the Knowles SWFK series of balanced armature receivers. These components are engineered specifically for miniaturized audio applications requiring high fidelity in small enclosures. The series is widely used in medical auditory devices due to its reliability and size constraints.

Replacement Considerations

Consult the official Knowles replacement guide for verified substitutes. Generic equivalents may not match the precise frequency response or impedance characteristics required for hearing aid compatibility.
