Speakers Procurement Notes

Verify the specific datasheet version provided by Knowles or authorized distributors to confirm current manufacturing status and compliance certifications. Ensure that the 313 Ohm impedance matches your circuit design requirements before procurement. Confirm packaging details, such as bulk quantities, align with your assembly line needs. Cross-reference part numbers to avoid confusion with similar models in the Knowles portfolio.

Speakers Selection Notes

Select this component when a small footprint and high efficiency are critical for the application. The 313 Ohm impedance requires matching amplifier output stages appropriately. Consider the top port orientation during mechanical design to ensure unobstructed sound projection. Verify thermal and environmental ratings against operational conditions.

Speakers Part Context

This model belongs to Knowles' lineup of precision acoustic transducers. It is engineered for applications demanding reliable performance in limited spaces. The balanced armature design distinguishes it from dynamic drivers, offering specific tonal characteristics suitable for voice and alert tones.

Speakers Replacement Considerations

Consult official substitution guides for compatible alternatives. Direct replacements must match the 313 Ohm impedance and rectangular package dimensions. Verify electrical and mechanical compatibility before switching suppliers.
