IN Brief:
- CM-HVLP surface mount mica capacitors span 1.5–4 kV DC and 10–750 nF across the component family.
- CF-PP140 metallised polypropylene capacitors cover 450–1,500 V DC and 0.8–210 µF, with operating temperatures reaching 140°C.
- The portfolio also includes separate 200°C film technology, CalRamic ceramics, integrated inductor-transformer structures, SVM busbars and stator production.
Exxelia is presenting a group of high-voltage capacitors, integrated magnetics and power distribution components for electronics operating under demanding electrical and thermal conditions. Its portfolio combines reconstituted mica capacitors, high-temperature polypropylene film parts, ceramic devices from CalRamic, magnetic assemblies and busbars. The technologies address separate functions in power conversion, from energy storage and filtering to magnetic coupling and high-current interconnection, with individual ratings determined by each component family.
The CM-HVLP range uses impregnated, reconstituted mica dielectric in low-profile surface mount packages. Across the series, rated DC voltage extends from 1.5 to 4 kV and capacitance from 10 to 750 nF, with a specified operating temperature range of −55°C to 125°C. Exxelia lists capacitance tolerances of ±10% and ±20%. These are catalogue ranges rather than specifications shared by every available part number, so voltage, capacitance and package must be selected together.
Mica capacitors can provide electrical stability in high-voltage pulse and filtering circuits while reducing the board area occupied by larger leaded assemblies. The surface mount format also brings the component closer to the circuit’s physical layout: conductor spacing, creepage, clearance and PCB insulation arrangements must accommodate the working voltage. In designs exposed to repetitive charge and discharge, component selection must account for the pulse profile as well as its nominal capacitance and voltage rating.
Exxelia’s CF-PP140 family uses metallised polypropylene for power capacitors operating at temperatures up to 140°C. The catalogue spans 0.8–210 µF, with DC ratings of 450–1,500 V specified at 85°C in the technical datasheet. This distinguishes the rated voltage reference condition from the maximum permitted operating temperature. Electrical stress and expected lifetime must therefore be assessed against the intended temperature and current, rather than applying the highest figures across all conditions.
The CF-PP140 construction is described as self-healing and low inductance, with tinned copper radial leads and an epoxy sealed thermoplastic case. Exxelia gives energy density of up to 250 J/L for selected configurations and has cited an improvement of approximately 30% against comparison products. The claimed density depends on the design and reference used, while the final capacitor size follows the required capacitance, voltage margin and installation environment. The range was originally introduced earlier in 2026.
The manufacturer’s separate film offering extends to parts intended for operation at 200°C. This capability belongs to a different technology from CF-PP140’s 140°C polypropylene range. Keeping the materials and ratings separate is especially important where power equipment faces both high ambient temperatures and internal heating caused by ripple current. The dielectric, packaging and cooling path together establish the usable operating envelope for a selected component.
High-voltage ceramic devices from CalRamic add another construction option, particularly for circuits requiring compact capacitance and low equivalent series resistance at high frequency. Exxelia is highlighting CalRamic single-layer disc capacitors for power supplies, avionics and RF applications following the acquisition of the specialist business. Ceramic selection depends on the actual dielectric and device geometry, which determine capacitance stability, voltage withstand and mechanical handling in the intended assembly.
Within its magnetic portfolio, Exxelia combines an inductor and transformer within a shared core structure. In a converter, an inductor is used to store or smooth energy, while transformer windings couple energy between circuits and may provide isolation. Sharing the magnetic structure can reduce duplicated material and mounting space, although core flux, leakage inductance, copper loss, winding temperature and insulation still have to be resolved in the combined design. Those parameters directly influence conversion efficiency and thermal performance.
The company’s SVM busbars provide interconnections between power modules, capacitors and other assemblies carrying substantial current. Their conductor geometry influences resistance and stray inductance, both of which can affect losses, voltage transients and heating in switched power stages. Exxelia is presenting multiple busbar constructions rather than a single universal layout, leaving conductor dimensions, insulation and terminal positioning to be chosen for the current path and installation constraints.
Exxelia is also highlighting custom stator manufacturing in Morocco, covering materials, winding processes and industrialisation for specialised electric machines. These operations address the electromechanical part of the power system, where a repeatable winding arrangement, insulation and production control are necessary to manufacture the intended motor design. The capability is distinct from the electrical ratings of the capacitor and magnetic components, but it expands the group’s contribution to assemblies used in aerospace, defence and industrial equipment.
The selection will be exhibited at electronica in Munich from 10 to 13 November 2026. Several constituent products, including CF-PP140, were already introduced earlier in the year; the October development brings their detailed specifications together with CalRamic components, combined magnetics, busbars and stator manufacturing. Engineers specifying the equipment will use individual datasheets and qualification requirements to match the portfolio to voltage, temperature, frequency and mechanical demands.
