Raraion Omnidirectional Electret Microphone Cartridge with 150 mm Cable

The Raraion Omnidirectional Electret Microphone Cartridge offers a sensitivity of 58dB and a true omnidirectional polar pattern, picking up sound equally from all directions. Designed for reliable sound capture in a range of audio and communication applications, it is suited to conference calls, ambient noise recording, and hands-free communication devices.

Overview

This electret condenser microphone is known for its high sensitivity and stable performance. It requires a simple external bias resistor for operation and is supplied with a factory-fitted, 150 mm long screened cable for immediate integration. The screening helps reduce electromagnetic interference for cleaner audio signals, and the cable ends are insulated and tin-plated for good solderability and reliable electrical connections.

Key Features

• True omnidirectional polar pattern
• Electret condenser type with high sensitivity
• Factory-fitted 150 mm screened cable
• Insulated and tin-plated cable ends
• Sensitivity: 58dB
• Output impedance: 2.2kΩ
• Frequency response: 50Hz to 16kHz

Electrical Requirements

The microphone requires an external 1-2.2kΩ resistor for AF (audio frequency) decoupling and a coupling capacitor in the range of 0.1-4.7µF. It operates from a supply voltage of 1.5V to 10V, with a maximum drain current of 500µA, making it suitable for battery-powered portable electronics.

Applications

This versatile cartridge is suitable for professional and DIY audio projects, including intercom systems, voice recorders, hearing aids, and wireless communication devices. Its compact dimensions and frequency response from 50Hz to 16kHz make it suitable for voice and general audio applications.

Choose the Raraion Omnidirectional Electret Microphone Cartridge when you need a compact, omnidirectional microphone element with a factory-fitted screened cable for straightforward integration into audio and communication designs.
