PUI Audio Microphone, -26db Sensitivity, 0.02kHz Minimum Frequency Response - DMM-3526-B-R


This microphone is a Compact MEMS device designed to capture sound with uniform sensitivity from all directions in electronic and automation systems. It operates at low supply voltages and is intended for integration where space is limited and omnidirectional pickup is required. The unit connects via a pin-type Interface and is suitable for incorporation into sensor modules and embedded audio stages.

Features and Benefits:


• Omnidirectional polar response for consistent ambient pick‑up
• Frequency range from 0.02 kHz to 18 kHz for wideband sensing
• Sensitivity of -26 dB for clear signal detection
• Operates between 1.64V and 3.6V for low‑voltage designs
• Pin‑type connector compatible with standard board mounting
• Compact 3.5mm form factor for space‑constrained layouts

Applications


• Suitable for voice capture in IoT sensor nodes
• Ideal for environmental sound monitoring in automation
• Used with industrial control panels requiring omnidirectional audio
• Can be used for acoustic diagnostics in mechanical systems
• Suitable for integration into consumer electronics prototypes

What electrical supply range does it support for battery‑powered designs?


It functions across a low‑voltage window from 1.64V up to 3.6 V, enabling use with common single‑cell and regulated supplies.

How does the element perform across audio frequencies relevant to human speech?


The microphone responds from 20 Hz through 18 kHz (notated as 0.02 kHz to 18 kHz), covering sub‑bass to upper treble required for intelligible speech and many acoustic diagnostics.

What form of connection should I design for on the PCB?


The device uses a pin‑type connector interface, so provide corresponding through‑hole or header footprints to accommodate pin mating.

Are there regulatory material restrictions to consider during selection?


The component complies with REACH and RoHS standards, indicating conformity with common material restriction regimes.
