PUI Audio Microphone MEMS, 18 kHz

This omnidirectional MEMS microphone is designed to capture ambient audio for Compact electronic systems, providing a low-voltage sensing solution compatible with battery-powered and embedded designs. It is intended for integration onto boards that require small, high-sensitivity acoustic inputs and broad frequency coverage suitable for human-audible and near-subsonic signals.

• Omnidirectional pick-up provides uniform sound capture across angles
• Sensitivity of -26 dB enables detection of low-level audio signals
• Frequency range 0.02kHz to 18kHz preserves voice and environmental detail
• Operates from 1.5V to 3.6V for flexible low-voltage designs
• Pin-type connector simplifies PCB mounting and routing
• Meets RoHS and REACH standards for material compliance

• Suitable for voice capture in mobile devices and wearables
• Ideal for acoustic sensing in IoT endpoints and sensors
• Used for environmental noise monitoring in automation systems
• Can be used for input microphones in Compact consumer electronics
• Used with embedded controllers in electronics prototyping

It functions across a supply window from 1.5V up to 3.6V, allowing use with common single-cell and regulated supplies.

The transducer responds from 0.02kHz to 18kHz, covering infrasonic-to-audio ranges relevant to speech and many environmental sounds.

It uses a pin-type connection designed for direct insertion or soldering to a printed circuit for Compact integration.

The device conforms to RoHS and REACH material restrictions, aligning with regulations on restricted substances.

It employs MEMS sensing to deliver a Compact form factor and consistent electro-acoustic behaviour.
