EK-26695-C36

Microphones Overview

The EK-26695-C36 is an omnidirectional analog electret condenser microphone manufactured by Knowles. It operates within a frequency range of 100 Hz to 5.5 kHz and features a sensitivity of -53dB ±2dB at 74dB SPL. The device requires a supply voltage between 0.9 V and 10 V, with a rated voltage of 1.3 V and a supply current of 50 µA. It has an impedance of 4.4 kOhms and utilizes a side port located on the component body. The microphone is housed in a rectangular surface-mount package measuring 5.56 mm in length, 3.99 mm in width, and 2.26 mm in maximum height, terminating via solder pads.

Microphones Procurement Notes

Verify the specific suffix C36 against official Knowles documentation to confirm terminal configuration and packaging details. Ensure compatibility with the required operating voltage range of 0.9 V to 10 V and check for RoHS compliance status relevant to your region. Confirm that the 4.4 kOhm impedance matches your preamplifier input requirements before finalizing procurement.

Microphones Selection Notes

Select this component when an omnidirectional pickup pattern is required for compact audio applications. The low supply current of 50 µA makes it suitable for battery-powered devices. Verify that the 100 Hz to 5.5 kHz frequency response aligns with the target voice bandwidth needs. Ensure the PCB layout accommodates the 5.56 mm x 3.99 mm footprint and side-port alignment for optimal acoustic performance.

Microphones Part Context

This part belongs to the EK series of microphones from Knowles, designed for general audio applications. The series typically offers various sensitivity and size options. The EK-26695-C36 specifically provides a standard sensitivity level with a rectangular form factor suitable for surface-mount assembly processes in consumer electronics manufacturing.

Microphones Replacement Considerations

EK-26597-C36 shares similar electrical characteristics including -53dB sensitivity and 4.4 kOhm impedance but differs in frequency range (100 Hz ~ 5 kHz). Verify dimensional compatibility and port positioning before substitution.
