MIAMI, FL – September 5, 2024 – Raltron, a global leader in high performance frequency management components, wireless antenna products and audio components announces the release of the RMIC Series, a comprehensive line of electret condenser microphones. 

Designed for a wide variety of applications, these microphones offer compact size, low power consumption, a wide sensitivity and frequency response range, long operational life, all at competitive price points. 

These advantages make the RMIC series a good choice where high-quality sound capture and reliable performance are required. Applications include headsets, computers and laptops, tablets, cellphones, gaming, audio recording equipment, surveillance and security systems, automotive applications (e.g. hands-free systems), smart home devices and voice assistants, wearable technology, access control systems, medical, radios and remote control applications.  

The RMIC microphones are available in sizes from 3.0mm ~ 9.7mm and offered with omnidirectional, unidirectional and noise-canceling options. Max voltage input options are 3.6, 5 and 10 VDC with sensitivity ranges from -26 ~ – 45 dBV/Pa in solder pad, through-hole and wire termination options. When required, Raltron offers custom wire lead lengths and connectors with RMIC Series microphone assemblies with a solder pad.   

The RMIC microphones’ wide frequency response allows them to capture a broader range of sounds, handle a variety of audio sources, and provide a more immersive audio experience for podcasting, voiceovers and field recording. With their low power consumption, RMIC microphones can be powered by small batteries or directly by the device which make them ideal for battery-operated and portable devices.
