CI-30050-000

Overview

The Knowles CI-30050-000 is a balanced armature speaker transducer designed for high-fidelity audio reproduction in space-constrained applications. It features a frequency range of 200 Hz to 4.6 kHz and an impedance of 25 Ohms. The device has a top port configuration with a sensitivity of 118.5 dB and physical dimensions of 9.47 mm in length and 4.1 mm in depth.

Feature Summary

• Balanced armature design for high-fidelity sound reproduction
• Top port configuration for directional audio output
• Optimized for reduced distortion and feedback

Applications

• Space-constrained hearing aids
• In-ear monitors
• Compact audio receivers

Procurement Notes

Verify the specific impedance variant required, as sources indicate both 25 Ohm and 46 Ohm configurations exist within the CI-30050 series. Confirm packaging type (bulk) and ensure compatibility with the target acoustic chamber design. Cross-reference the datasheet for exact mechanical tolerances.

Selection Notes

Select this component when high fidelity and low distortion are critical in miniaturized form factors. The 25 Ohm impedance suits standard driver circuits. Ensure the application requires the specified 200 Hz to 4.6 kHz bandwidth. Verify mechanical fit against the 9.47 x 4.1 mm envelope.

Part Context

Part of the Knowles Speakers & Transducers family, specifically the CI series. Designed for premium audio applications requiring compact size and high performance. Manufactured by Knowles Electronics.

Replacement Considerations

Check for other CI-series variants with matching impedance (25 Ohm vs 46 Ohm). Verify acoustic port orientation (top port) matches the enclosure design. Ensure frequency response overlaps sufficiently with the original requirement.
