EXXELIA at PCIM 2019

Exxelia will exhibit custom design power transformers and inductors as well as capacitors at PCIM in Nuremberg, Germany, from May 7th to 9th 2019 in booth #136.


Notable at Exxelia’s booth #136 will be custom design power transformers & inductors such as: 

FERRITE TRANSFORMER 100kVA-20kHz

This transformer combines high power up to 100kVA, at very high frequency 20kHz, while still providing a weak leakage inductance. Used in an isolated DC/DC converter, its unique morphology made of U and I 126 magnetic circuit improves considerably thermal dissipation while the litz wire winding reduces high frequency losses. Characterized by a primary circuit at 540V / 350Arms and a secondary winding at 270A, this transformer ensures high performance and maximum leakage current reduction.

3 PHASE INDUCTOR 3x5,5mH-9kHz 

Used in a high performance converter, this three-phase common mode choke withstands the highest current up to 580A thanks to the use of copper bar for winding while ensuring a minimal inductance of 1,4mH and filtering the far-reaching noise. This deisgn is characterized by its extreme reliability thanks to its magnetic circuit made of 24 nanocrystalline tores, chosen to guarantee a stable inductance value across the temperature range -30°C to +140°C.

Exxelia at Space Tech Expo

ESA QPL Film Capacitors PM907S and PM948S are full series of Polyester Film Capacitors. PM907S products are suitable for voltages from 50V up to 1250V and offer capacitance values from 82nF up to 180μF. PM948S can be used from 50V up to 630V with capacitance values from 22nF up to 47μF. Both series can support extreme conditions with temperatures from -55°C to +125°C, and offer high energy density, low ESR & ESL and high RMS current. Film capacitor Series PM907S and PM948S are ESA QPL certified according to the ESCC Detail Specification No. 3006/025 and 3006/026   Smallest ESA QPL Ceramic Capacitor of the Market Exxelia ranges of low voltage MLCC for surface mounting, CEC19 and CNC19, have achieved the ESA Qualified Part List status under the criteria of the European Space Component Coordination’s (ESCC) 3009/042 and 3009/043 respectively. The  0402 size QPL-qualified parts are available from 10V to 25V, enabling substantial miniaturization and cost-saving. They are available either in the very stable NPO dielectric (type 1) or the high capacitance X7R (type 2). CEC and CNC series combine high capacitance values with high thermal and voltage stability. Versions with polymer terminations are also QPL-certified.   Miniature EMI filters for space application Exxelia’s gold-plated glass-sealed EMI filters SFC030 is the solution of choice to protect several embedded power supplies and data lines.  These small and reliable filters are available up to 5A @ 200V and 22nF.  Available in a Kovar package, the better alternative to steel for enhanced temperature cycling resistance, all Exxelia’s EMI filters for space are ESA qualified according to ESCC 3008. Thanks to this extensive experience in stringent ESA testing, Exxelia is able to adapt the tests of any filter according to any need (example: SMD 20A chip, 0pF capacitor value for an arrays of filters).

HIGH VOLTAGE CERAMIC CAPACITORS BASED ON BRAND NEW DIELECTRIC MATERIAL

No more compromises between stability and capacitance! The brand new C48X material combines most advantages of NPO and X7R dielectrics, enabling the new high power and high frequency ceramic capacitor range to provide great stability in voltage, high capacitance, great dissipation factor and fast charge/discharge. Miniaturization is a driving need for future electronics pieces of equipment. This evolution, true whatever the application, leads Exxelia Technologies (ex-Eurofarad) to develop a brand new high voltage ceramic capacitors range based on a new dielectric material named C48X, combining most of the advantages of NPO and X7R dielectrics. Compared to X7R material, C48X dielectric allows to get the same capacitance values under working voltage with the unrivaled advantage of a very low dissipation factor (less than 5.10-4). Besides, it can also withstand very high dV/dt, up to 10kV/μs, which makes it the solution of choice for pulse and fast charge/discharge applications. Thus capacitors with C48X dielectric appear to be ideally suited for power applications where heat dissipation may be detrimental to performances and reliability. Exxelia Technologies’ capacitors based on the C48X material have been developed from 200V to 5kV with chip sizes ranging from 1812 to 16080, allowing a maximum capacitance value of 10μF 200V (10 times more than with an NPO ceramic). The standard stacked versions are proposed with a maximum capacitance value of 47μF 200V. Regarding the mounting of these capacitors, many configurations are possible to be compatible either with surface mounting or through-hole mounting. All these versions can be suitable for space use and can be designed in order to avoid any whisker growth risk (10% min lead in all tin-lead alloys used). The introduction of the C48X range in the EPPL (European Space Agency Preferred Parts List) for space is in progress for sizes 0603 to 6560 from 100V to 1kV up to size 1210 and up to 5kV until the size 6560). Some typical applications: • 400Hz Aircraft • Defense • Space • Precision/filtering capacitance in thermally challenged environment for AC or DC voltage
