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.”
