EJ-23018-000

Speakers Overview

The Knowles EJ-23018-000 is a compact receiver speaker designed for audio applications requiring high sensitivity output. It features an impedance of 380 Ohms and operates within a frequency range of 200 Hz to 4.5 kHz. The component has physical dimensions of 6.3 mm in height, with a length of 6.3 mm and a width of approximately 4.32 mm. It utilizes a top or side port configuration depending on the specific variant documentation, offering acoustic performance suitable for portable electronic devices.

Speakers Feature Summary

• Compact rectangular form factor suitable for space-constrained designs
• High sensitivity output capability for efficient audio reproduction
• Fixed impedance design optimized for specific driver circuits

Speakers Applications

• Portable consumer electronics audio output
• Medical device acoustic signaling
• Industrial control panel feedback systems

Speakers Procurement Notes

Verify the specific port orientation (top vs. side) required for your enclosure design, as sources indicate variations. Confirm RoHS compliance status with the supplier prior to ordering, as documentation may vary by production batch. Ensure the 380 Ohm impedance matches your amplifier output stage to prevent signal distortion or power mismatch issues during integration.

Speakers Selection Notes

Select this component when a small footprint and high acoustic efficiency are prioritized over wideband frequency response. The fixed 380 Ohm impedance limits compatibility to specific driver types, so verify circuit matching before adoption. Consider the mechanical mounting constraints imposed by the 6.3 mm height profile during PCB layout and enclosure design phases.

Speakers Part Context

This part belongs to the Knowles Speakers & Transducers family, specifically engineered for receiver-grade audio applications. It represents a specialized solution for devices needing reliable acoustic output in minimal spaces, distinguishing itself from general-purpose loudspeakers through its focused frequency range and impedance characteristics tailored for voice or tone reproduction.

Speakers Replacement Considerations

Direct substitutes require matching 380 Ohm impedance and similar dimensional constraints. Verify that alternative components support the 200 Hz to 4.5 kHz operational range. Cross-reference mounting hole patterns and port locations to ensure mechanical compatibility without redesigning the host assembly.
