GD-31288-000

Speakers Overview

The Knowles GD-31288-000 is a balanced armature receiver designed for audio applications. It operates within a frequency range of 100 Hz to 6.7 kHz and features an impedance of 281 Ohms. The component has a power handling capacity of 10 mW and a sensitivity level of 100 dB. It utilizes top rectangular packaging with a protruding terminal configuration, ensuring compatibility with standard surface-mount assembly processes.

Speakers Feature Summary

• Balanced armature technology provides high efficiency and stability
• Top rectangular package design facilitates surface-mount integration
• Protruding terminals enable reliable soldering connections

Speakers Applications

• Hearing aid receivers
• In-ear monitor systems
• Voice communication headsets

Speakers Procurement Notes

Verify the specific datasheet revision and mechanical outline drawing before finalizing designs. Confirm that the 281 Ohm impedance matches the target circuit requirements. Ensure the 10 mW power rating aligns with the intended drive levels to prevent damage. Check for any RoHS compliance documentation if required by regional regulations.

Speakers Selection Notes

Select this component when a compact balanced armature solution is needed for voice or narrowband audio. The 281 Ohm impedance suits circuits requiring higher voltage drive rather than high current. Consider the 100 Hz to 6.7 kHz bandwidth for speech-centric applications where extended low-frequency response is not critical.

Speakers Part Context

This part belongs to Knowles' line of balanced armature speakers, which are widely used in miniature audio devices. The GD series typically offers consistent performance across manufacturing batches. These components are engineered for reliability in small form-factor electronics where space constraints limit the use of dynamic drivers.

Speakers Replacement Considerations

Direct substitutes must match the 281 Ohm impedance and balanced armature architecture. Verify dimensional compatibility with the existing PCB footprint. Ensure the replacement maintains similar sensitivity and frequency response characteristics to preserve audio quality.
