Low-pass filter capacitors quash EMI
Two series of Exxelia Technologies Multilayer Ceramic Discoidal Capacitors used for power supply and digital signalling have been released by New Yorker Electronics.
The FC030 is feedthrough mounted on shielding enclosures and the FCM030 series is designed to prevent EMI on printed circuit boards.
These low-pass filter solutions are mainly used for EMI suppression in electronics systems in Avionics, Military, Medical, Aerospace and other critical applications.
Exxelia Technologies (formerly Eurofarad), part of Exxelia Group, has developed several ranges of miniature filters with different low-pass configuration (C, L, Pi, T, 2xPi, 2xL and 2xT) mainly intended to protect electronic equipment from interferences.
The company produces sophisticated filters assembling Exxelia Group’s manufactured ceramic capacitors (X7R/ NPO) with ferrite inductors or winding cores in a shielding case.
This solution’s main benefits are performance, reliability and optimal traceability.
This filter in a shielding case provides a good metallic package, thus ensuring high shielding performances with attenuation up to 10 GHz.
Among the available options are glass sealing, steel or kovar package using tin, silver or gold plating treatments to withstand any thermally or mechanically challenged application.
The Exxelia FC030 series is a feedthrough filter to prevent not only EMI conduction but also EMI radiation on power supply or data signals designs up to 200V.
FC030 insertion loss can be 20dB at 1MHz to reach 70dB up to 10 GHz. FC030 series is extremely performant on low frequencies applications.
The component also offers very low capacitance values starting from 5pF allowing it to protect high bandwidth data signals.
It has an operating temperature range from -55°C up to +175°C and is ESA qualified.
The FCM030 features the same design and performances as FC030 and is intended for surface mount devices.
It is packaged in full metallic silver-plating.
This allows optimal contact with ground plane that improves the interferences flow to the ground. The series is particularly fit for amplifiers, radars, sensitive HMI and accurate measuring.
The FC030 comes with glass or resin sealing, and in a solder-in or threaded package.
NYE is franchise distributor of the Exxelia Group, and supplies its full line of Film, Mica, Tantalum, Aluminum Electrolytics and Ceramic Capacitors as well as its EMI/RFI Filters, Magnetics, Position Sensors, Slip Rings and Rotary Joints.
