The device has a sensitivity of -37 dB, an impedance of 2 ohms, and a maximum current rating of 400 uA. Its physical dimensions include a diameter of 9.7 mm and a depth of 4.5 mm.

Feature Summary

Unidirectional acoustic design for focused sound capture
Low power consumption suitable for battery-operated devices
Compact cylindrical form factor with surface mount solder pads

Applications

Consumer electronics audio input
Portable communication devices
Voice recognition systems

Procurement Notes

Verify the specific suffix 'P' against the official Same Sky datasheet to confirm exact termination style and packaging configuration. Ensure the operating voltage and sensitivity specifications align with the target application requirements before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, unidirectional microphone is required for compact electronic assemblies. Consider the 2-ohm impedance and 400 uA current draw during preamplifier circuit design to ensure proper signal matching and power budget compliance.

Part Context

This microphone belongs to the CMC series of miniature electret microphones from Same Sky. These components are engineered for high reliability in small-footprint applications, offering consistent performance across various consumer and industrial electronic environments.

Replacement Considerations

Consult the official Same Sky replacement guide or cross-reference list for verified substitute part numbers. Do not assume compatibility based solely on similar electrical parameters without verifying mechanical fit and pinout definitions.
