Speakers Procurement Notes

Verify the specific revision code and packaging format (e.g., tape and reel quantity) against the manufacturer's current datasheet before ordering. Ensure compatibility with existing acoustic chambers and PCB footprint dimensions. Confirm RoHS compliance status if required by your manufacturing standards.

Speakers Selection Notes

Select this component when a compact, high-output receiver is needed for space-constrained audio devices. The 130 Ohm impedance suits specific driver circuits, while the 96 dB SPL ensures adequate volume. Consider the side port orientation during mechanical layout to optimize acoustic performance.

Speakers Part Context

This part belongs to Knowles' FH series of balanced armature receivers. These components are engineered for miniaturized audio applications requiring precise sound reproduction. The series offers various impedance and sensitivity options to match different electronic designs.

Speakers Replacement Considerations

Direct substitutes must match the 130 Ohm impedance, 96 dB SPL, and rectangular SMD package. Verify pinout and acoustic port alignment. Consult Knowles for approved alternates within the FH series or equivalent balanced armature models from other manufacturers.
