Speakers Feature Summary

• Balanced armature transducer technology
• Top-mount rectangular package design
• High impedance characteristic

Speakers Applications

• Mobile communication devices
• Wireless headsets
• Portable audio equipment

Speakers Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturing updates may occur. Confirm that the 144.4 Ohm impedance matches the circuit requirements precisely. Ensure the top-mount orientation aligns with the mechanical assembly constraints. Check RoHS compliance status if required by regional regulations.

Speakers Selection Notes

Select this component when a high-impedance balanced armature receiver is required for space-constrained designs. The 144.4 Ohm impedance necessitates compatible driver circuits compared to standard 32 Ohm or 16 Ohm speakers. The wide frequency range supports voice and limited music reproduction needs.

Speakers Part Context

This part belongs to the Knowles balanced armature speaker family. These components are widely used in consumer electronics where size and acoustic performance are critical. The GD series typically offers consistent acoustic output across various portable device form factors.

Speakers Replacement Considerations

Direct substitutes must match the 144.4 Ohm impedance and rectangular top-mount package. Verify frequency response overlap between 100 Hz and 6.7 kHz. Mechanical footprint compatibility is essential for PCB replacement without redesign.
