The component operates within a voltage range of 3 V to 10.0 V with a supply current of 500 µA. It utilizes solder pads for termination and measures approximately 0.197 inches in length.

Feature Summary

Omnidirectional acoustic pickup pattern
Electret condenser transducer technology
SMD surface mount package configuration

Applications

Analog audio signal capture systems
Voice recognition hardware modules
Consumer electronic device microphones

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to ensure correct sensitivity and packaging specifications. Confirm that the required external low-noise amplifier or audio codec microphone input matches the analog output level requirements of this component before finalizing procurement orders.

Selection Notes

Select this component when an omnidirectional electret microphone is required for analog circuit integration. Ensure the design accommodates the specified 500 µA supply current and provides adequate amplification for the -44 dB sensitivity output level. Verify physical space constraints align with the SMD package dimensions.

Part Context

This model belongs to the TOS series of surface-mount electret condenser microphones from PUI Audio. These devices are engineered for compact consumer electronics where standard microphone form factors are insufficient. The series emphasizes reliable analog performance in small footprint applications.

Replacement Considerations

Check for direct substitutes within the same TOS series family. Verify pinout compatibility and electrical characteristics such as sensitivity and operating voltage ranges before substituting with other manufacturers' equivalent omnidirectional electret microphones.
