Speakers Procurement Notes

Verify the specific datasheet revision and RoHS compliance status prior to procurement. Confirm that the 130 Ohm impedance matches the target amplifier output requirements. Ensure the top port orientation aligns with the mechanical housing design to prevent acoustic obstruction during assembly.

Speakers Selection Notes

Select this component when high sensitivity is required in a miniature form factor. The 130 Ohm impedance suits specific driver configurations. Verify that the 2.64 mm height constraint fits the available enclosure space. Consider the 200 Hz lower frequency limit for bass response requirements.

Speakers Part Context

This part belongs to the Knowles FH series of miniature balanced armature speakers. These components are engineered for high-fidelity audio reproduction in constrained spaces. The series is widely utilized in medical audio devices where size and performance are critical constraints.

Speakers Replacement Considerations

Check for direct cross-reference part numbers from Knowles or authorized distributors. Verify impedance and sensitivity compatibility before substituting. Ensure mechanical footprint and terminal configuration match the existing PCB layout.
