Innovative low pass filters
Exxelia 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.
Low-pass filter solutions are mainly used for EMI suppression in electronics systems. Exxelia Technologies (ex-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.
Exxelia Technologies 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.
Considering a filter in a shielding case implies a good metallic package to insure high shielding performances with attenuation up to 10 GHz. Among options, Exxelia offers glass sealing, steel or kovar package using tin, silver or gold plating treatments to withstand any thermally or mechanically challenged applicaiton.
Exxelia offers innovative EMI suppression filter solutions providing great shielding performance including the FC030 feedthrough mounted on shielding enclosure and FCM030 series designed to prevent EMI on printed circuit board.
FC030 series is feedthrough filter allowing 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.
On the other hand, FC030 can offer very low capacitance values starting from 5pF allowing to protect high bandwidth data signals. Operating temperature from -55C° up to +175C°. FC030 series is ESA qualified.
FCM030 features same design and performances’ as FC030 and is intended for surface mount devices. FCM030 is packaged in full metallic silver plated allowing optimal contact with ground plane that improves the interferences flow to the ground.
The series particularly fit for amplifiers, radars, sensitive HMI, accurate measuring.

Two new ranges of MIL-qualified tantalum capacitors: MIL39006/22 & MIL39006/25 The recently introduced ranges of MIL-qualified tantalum capacitors will be showcased on the company booth. MIL 39006/22 and MIL 39006/25 respectively equivalent to CLR79 and CLR81 types featuring hermetically sealed cylindrical tantalum cases and axial leads are available in T1, T2 T3 and T4 cases with extended capacitance and voltage ratings. MIL 39006/22 is qualified for voltages from 6V to 125V and provides from 1200µF @6V to 56µF @125V. MIL 39006/25 is qualified for voltages from 25V to 125V and delivers from 680µF @25V to 82µF @125V. Both ranges combine high energy density with a large operating temperature range of -55°C - +125°C and H vibrations and shocks resistance. PHM 912, very high energy density film capacitors PHM 912 is a new standard series of film capacitors based on a novel metallized plastic film dielectric from Dupont Teijin®. The PHM 912 capacitors are specifically designed for DC filtering or energy storage. Very stable in both temperature and frequency, they are well-adapted for applications such as filtering in H.F. switch mode power supplies, DC link or decoupling. The range can withstand temperatures up to 155°C and up to 175°C in custom version. With their high energy density, these capacitors allow highly integrated power filters. Their compact construction results in a low ESR, ESL and excellent high current and frequency performances. The series provides 250V @68µF and 0,27µF @1000V. The PHM 912 series makes significant advances over previous technologies by combining the benefits of excellent temperature resistance with superior energy densities, making it one of the most compact capacitors on the market. Felsic HV, long lifetime and high voltage screw terminal aluminum electrolytic capacitor The Felsic HV family of aluminum electrolytic screw terminal capacitors provides great performances in energy density combined with ultra-long lifetime. For instance, 6 800µF @450V fit into a volume of Ø77x220mm and can withstand 200,000 hours between 0 to 70° under 37Amps, which makes them the perfect choice for use in rolling stock traction systems or the CVS. The family also has one of the lowest ESR of its class with less than 10m0hms in most cases. Products are available for voltages from 160 to 450Vdc, and offer capacitance values from 1500μF up to 47 000μF offering the best compromise between reliability and compactness.
