Knowles Introduces FM2 Range of Non-Magnetic X7R Low Loss MLCCs for Medical Imaging and High-Frequency Applications

The X7R Low Loss range delivers industry-leading low ESR and high Q performance while ensuring zero magnetic interference. 

ITASCA, IL, August 27, 2025 — Knowles Corporation (NYSE: KN), a market leader and global provider of high-performance capacitors and RF products, has announced the launch of its FM2 Range of Non-Magnetic X7R Low Loss Multilayer Ceramic Capacitors (MLCCs). The X7R Low Loss range of capacitors is engineered to provide lower equivalent series resistance (ESR)/higher Q compared to standard X7R capacitors, making them ideal for magnetic resonance imaging (MRI) systems and low-noise amplifier (LNA) applications.

Key Features & Advantages:

• Ultra-Low ESR: Minimizes power loss and reduces heat dissipation.
• High Q Factor: Ensures superior signal integrity in RF applications.
• Non-Magnetic Design: Prevents interference in MRI and other high-precision, non-magnetic systems.
• Competitive ESR Performance: Meets or exceeds the industry-leading standards set by leading competitors.
• Drop-in Compatibility: Designed for compatibility with standard form factors for seamless integration into existing designs.

“At Knowles, we prioritize our customers’ needs, and the FM2 range is a testament to that commitment,” said Victor Lu, Applications Engineer at Knowles. We understand that MRI OEMs and LNA manufacturers require highly reliable, application-specific solutions, and we are dedicated to providing them with the best possible component choices.”
