Microphones Procurement Notes

Verify the specific suffix 'L' against the manufacturer's latest datasheet to confirm dimensional tolerances and lead finish specifications. Ensure that the required operating voltage aligns with the 2V to 10V range documented for this part number. Cross-reference the impedance value of 2.2 kOhms with your pre-amplifier input requirements to guarantee proper signal matching and noise performance in the final assembly.

Microphones Selection Notes

Select this component when an omnidirectional pickup pattern is required for general ambient sound capture rather than directional focusing. The wide frequency response up to 15 kHz makes it suitable for applications requiring clear voice reproduction or broad-spectrum audio detection. Consider the low bias current requirement if power efficiency is a critical constraint in the battery-operated system design.

Microphones Part Context

This model belongs to PUI Audio's line of standard electret condenser microphones designed for integration into compact electronic devices. The series typically offers standardized dimensions and electrical characteristics to facilitate easy replacement and design-in processes across various product categories including appliances and consumer gadgets.

Microphones Replacement Considerations

Direct substitutes may include other omnidirectional electret microphones with similar -42 dB sensitivity and 2.2 kOhm impedance. Verify pinout compatibility and physical footprint before substitution. Alternative parts must support the same 2V to 10V operating voltage range to ensure functional equivalence without circuit modification.
