• High sensitivity rating of 121 dB for efficient sound projection
• Lead-free construction ensuring environmental compliance

Speakers Applications

• General purpose audio output devices
• Compact consumer electronics
• Portable communication equipment

Speakers Procurement Notes

Verify the exact part number EJ-26775-000 against official Knowles documentation to ensure compatibility. Confirm that the 36 Ohm impedance and 121 dB sensitivity meet specific circuit requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure mechanical fitment within the 6.33 x 4.32 x 5.97 mm envelope.

Speakers Selection Notes

Select this component when a small rectangular speaker is required for general audio tasks. The 36 Ohm impedance should match the driving circuit's output capabilities. Consider the 200 Hz to 4.8 kHz frequency response for voice or limited-bandwidth audio needs. The high sensitivity reduces power consumption requirements compared to lower sensitivity alternatives.

Speakers Part Context

This speaker belongs to the Knowles lineup of transducers designed for modern electronic devices. It represents a standard solution for basic audio feedback or notification functions where size is a critical constraint. The rectangular shape allows for flexible PCB layout integration compared to circular speakers.

Speakers Replacement Considerations

Substitutes must match the 36 Ohm impedance and similar physical dimensions. Verify that alternative speakers maintain comparable sensitivity levels to preserve volume output. Ensure the replacement supports the same operating frequency range.
