WT83 - High Capacitance wet tantalum

With 470µf @100V in a D size, WT 83 is a pass to miniaturize your impactful miniaturization of existing or new designs!


Capacitance values have been strongly increased with Exxelia's new range of tantalum capacitors: 

  • WT83 is an extension of the ST79 families (according to CLR93 MIL values) but with double the capacitance. That is a pass for impactful miniaturization of existing designs by playing on both size and weight (for instance, WT83 offers  470µf  100V in a D size, whereas ST79 only gives 220µF in the same other conditions).

Innovative low pass filters

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.
