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).
Exxelia at PCIM
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.
SPACE & MILITARY GRADE PASSIVES AT CMSE - BOOTH # B13 -
CMSE is one of the most recognized conference dedicated to the use of component in military and space systems. As a key supplier of highly reliable passive components, Exxelia will be displaying in booth B13, a wide variety of military and space-qualified capacitors (ceramic, tantalum, film, electrolytic aluminum), wound magnetics solutions and EMI/RFI filters. 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 (B13). MIL 39006/22 and MIL 39006/25 respectively equivalent to CLR79 and CLR81 types feature 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 56 µF @ 125V. MIL 39006/25 is qualified for voltages from 25V to 125V and delivers from 680µF @ 25V to 82 µF @ 125V. Both ranges combine high energy density with a large operating temperature range of -55°C - +125°C and H vibrations and shocks resistance. Alsic 20G, Aluminum Electrolytic capacitors with large operating temperatures Alsic 20G is a range of radial leaded aluminum electrolytic capacitors for typical use in military and aerospace high frequency switch-mode power supplies requiring advanced performance under all operating conditions. Alsic 20G operational rated life is 8,000 hours at rated voltage and 105°C, and provides from 330µF @ 500V to 80 000μF @16V. The range features ruggedized design with insulating aluminum case and tin coated leads. With capacitance stability at high temperature, low inductance and impedance, competitive ESR and high ripple current, these capacitors are perfectly adapted for mission-critical applications. C48X dielectric: NPO and X7R advantages combined Under working voltage, C48X dielectric provides equivalent capacitance values to an X7R material with the advantage of a very low dissipation factor (less than 5.10-4). It can also withstand very high dV/dt, up to 10kV/µs which makes it perfect for pulse and charge/discharge applications for firing units. Exxelia’s C48X capacitors, available from 200V to 5kV with EIA sizes from 1812 to 16080, are ideally suited for power applications where heat dissipation may be detrimental to performances and reliability, such as 400Hz Aircraft, Ignition systems, and Space, or as Precision/filtering capacitance in thermally challenged environment for AC or DC voltage.
