Procurement Notes
Verify the manufacturer designation as Same Sky, formerly CUI Devices, to ensure correct sourcing. Confirm that the operating voltage requirements align with the 4.5 V to 10 V specification. Ensure the PCB layout accommodates the 9.70 mm diameter and PC pin termination style. Cross-reference the sensitivity and impedance values against system design constraints.
Selection Notes
Select this component when an omnidirectional response is required for broad sound field capture. The low supply current of 500 µA makes it suitable for battery-powered applications. Verify compatibility with the target voltage range of 4.5 V to 10 V. The standard PC pin termination simplifies assembly compared to surface mount alternatives.
Part Context
This part belongs to the Same Sky electret condenser microphone series. It is designed for general audio applications requiring reliable analog signal output. The product line emphasizes standard form factors and established electrical characteristics for widespread compatibility in consumer electronics.
Replacement Considerations
Check for direct substitutes within the Same Sky CMA series or equivalent models from other manufacturers offering identical 9.70 mm diameter and PC pin termination. Ensure replacement parts match the 2200 Ohm impedance and -42 dB sensitivity specifications.
