FC-30001-000

Speakers Overview

The Knowles FC-30001-000 is a balanced armature speaker transducer designed for audio applications. It features an impedance of 845 ohms and a sound pressure level efficiency of 100 dB. The device operates within a frequency range of 200 Hz to 5.2 kHz. Physical dimensions include a length of 5.17 mm, a depth of 3 mm, and a side port configuration.

Speakers Feature Summary

• Balanced armature transducer architecture
• High efficiency output at 100 dB
• Side port acoustic design

Speakers Applications

• Hearing aids
• In-ear monitors
• Medical audio devices

Speakers Procurement Notes

Verify the specific port orientation (side vs. top) as distributor listings may vary in description accuracy. Confirm impedance matching with the driving circuitry, as the 845-ohm value requires specific amplifier considerations. Ensure the operating frequency range aligns with the target audio application requirements before integration.

Speakers Selection Notes

Select this component when high fidelity and compact size are required for hearing assistance or professional audio monitoring. The balanced armature design offers superior transient response compared to dynamic drivers. Consider the 845-ohm impedance load when designing the output stage of the audio system.

Speakers Part Context

This part belongs to the Knowles balanced armature speaker family, widely used in miniaturized audio electronics. It serves as a critical transducer in devices requiring precise sound reproduction in small form factors. The product line is standard for hearing aid manufacturers and premium audio equipment producers.

Speakers Replacement Considerations

Direct substitutes must match the 845-ohm impedance and 100 dB sensitivity. Check physical footprint compatibility, specifically the 5.17 mm length and 3 mm depth. Verify that alternative models support the same 200 Hz to 5.2 kHz frequency response curve.
