FM2 Range of Non-Magnetic X7R Low Loss MLCCs for Superior Performance in Medical Imaging and RF Applications

Written by Victor Lu | Aug 27, 2025 2:24:24 PM

Engineers designing for medical imaging and high-frequency applications need components that ensure minimal power loss, high signal integrity, and zero magnetic interference.

Knowles’ new FM2 range of Non-Magnetic X7R Low Loss Multilayer Ceramic Capacitors (MLCCs) is engineered to deliver superior RF efficiency and uncompromised reliability. These MLCCs provide lower equivalent series resistance (ESR)/higher Q factor compared to standard X7R capacitors, making them ideal for MRI systems and low-noise amplifier (LNA) applications. 

 

Key Features:

  • Ultra-Low ESR: Reduces power loss and minimizes heat dissipation
  • High Q Factor: Ensures optimal signal integrity
  • Non-Magnetic Design: Eliminates interference, critical for MRI and other high-precision, non-magnetic environments
  • Competitive ESR Performance: Meets or exceeds industry-leading standards, ensuring superior performance
  • Drop-in Compatibility: Designed for seamless integration into existing systems without modifications 

The FM2 range is optimized for applications where high performance and non-magnetic properties are essential. Whether in MRI systems requiring interference-free operation or low-noise amplifiers demanding high Q performance, these capacitors ensure consistent and reliable results. 

Knowles continues to innovate in high-performance capacitor technology, offering industry-leading solutions that enhance efficiency, reliability, and integration flexibility.
