EM-24046-C36

Microphones Overview

The Knowles EM-24046-C36 is an omnidirectional electret condenser microphone designed for analog audio signal capture. It operates at a supply voltage of 1.3 VDC with a current rating of 50 uA. The device features a sensitivity of -54 dBA and an impedance of 4.4 kOhms. Its frequency range extends from 100 Hz to 10 kHz. Physical dimensions are 3.98 mm in length, 2.28 mm in depth, and 5.56 mm in width (based on variant EA-21867-C36 data often associated with this series, though specific EM-24046-C36 dimensions vary slightly by source; Mouser lists 0.141 in length/depth). It utilizes SMD/SMT termination.

Microphones Procurement Notes

Verify the part status carefully as multiple sources list the EM-24046-C36 as obsolete. Confirm availability through authorized distributors or secondary markets if new production units are required. Ensure the specific revision matches your design requirements due to potential variations in physical dimensions across similar Knowles models.

Microphones Selection Notes

Select this component when an omnidirectional response is required within a 100 Hz to 10 kHz bandwidth. The low operating voltage of 1.3 VDC makes it suitable for battery-powered portable applications. Consider the SMD package style for automated assembly processes. Verify impedance matching with the preamplifier input stage to ensure optimal signal transfer.

Microphones Part Context

This microphone belongs to the Knowles electret condenser family, which provides high-quality audio performance in small form factors. These components are widely used in mobile phones, laptops, and other portable electronics where space constraints limit the use of larger microphone types.

Microphones Replacement Considerations

The EM-23346-C54 is a similar omnidirectional microphone from Knowles but features different sensitivity (-52 dBA) and impedance (4.4 kohms) with SMD termination. Cross-reference physical dimensions and electrical characteristics before substitution.
