Speakers Procurement Notes

Verify the specific port configuration (top or side) against project requirements, as distributor descriptions may vary. Confirm that the SMD package dimensions align with PCB footprint constraints. Ensure compatibility with existing driver circuits given the 105.2 Ohm impedance specification. Request official datasheets to validate performance curves under intended operating conditions.

Speakers Selection Notes

Select this component when a small rectangular balanced armature receiver is required for SMD assembly. Consider the 100 dBA efficiency for applications demanding high volume from low power. Evaluate the 105.2 Ohm impedance against amplifier output capabilities. The 100 Hz to 6.67 kHz frequency range suits voice and limited-bandwidth audio transmission needs.

Speakers Part Context

This part belongs to Knowles' portfolio of precision acoustic components, specifically their balanced armature speaker line. These components are engineered for miniaturization and reliability in consumer electronics. The GD series typically offers consistent performance across manufacturing batches, supporting mass production environments.

Speakers Replacement Considerations

Cross-reference with other Knowles GD-series parts for dimensional compatibility. Verify impedance and sensitivity matches before substituting with non-Knowles equivalents to maintain acoustic performance integrity.
