PUI Audio Microphone ECM, 10 kHz

This microphone is a Compact electret condenser device designed for integration into electronic assemblies where clear voice capture and background noise reduction are required. It operates at low supply voltages and is intended for embedded audio modules and industrial signal acquisition, providing a focused pickup pattern suited to applications that need reduced environmental interference.

• Noise‑cancelling polar pattern reduces ambient interference during capture
• Sensitivity of -54dB enables reliable voice‑level detection in circuits
• High input impedance of 680Ω supports high‑impedance interfacing
• Frequency range from 0.1kHz to 10kHz preserves speech bandwidth
• Operates from 1.5 to 10V allowing flexible low‑voltage power designs
• Pin‑type connector simplifies PCB mounting and replacement

• Suitable for voice modules in automation controllers
• Ideal for handheld diagnostic instruments requiring voice input
• Used with embedded systems for audible event detection
• Can be used for intercom and communication panels in electrical rooms
• Used for retrofit replacement in small electronic devices

It uses a pin‑type connection that permits straightforward through‑hole soldering to PCBs for mechanical and electrical attachment.

The component complies with RoHS and REACH substance regulations applicable to electronic manufacturing.

The capsule length measures 9.7mm, allowing installation in tight spaces within assemblies.

It is an ECM requiring an appropriate bias and a preamplifier stage to match its electret element characteristics.
