Exxelia Introduces capacitor range for high-temperature and high-energy applications
Exxelia has announced the launch of a new range of polypropylene film capacitors, CF-PP140, developed to address the growing demand for compact, high-energy solutions capable of operating at elevated temperatures in mission-critical environments.
The CF-PP140 forms a comprehensive range of standard components designed for applications requiring high energy density in a compact footprint. They support operating voltages from 450 V to 1500 V, offer an energy density of up to 250 J/L while pushing the polypropylene operating temperature up to 140°C. These capacitors feature a standard footprint to ease system integration, making them suitable for constrained electronic architectures.
Complementary, Exxelia offers a higher level of integration by combining a CF-PP140 and busbar from Exxelia SVM into fully customised “Power Block” capacitors. These tailored blocks can meet customers’ specific size and electrical performance requirements, even in the most extreme applications.
The CF-PP140 product series provide an operating temperature capability of 140°C, compared to a typical 105°C for similar polypropylene film capacitors (PP), along with an energy density increase of approximately 30% versus competing solutions. For custom designs, energy density can reach 250 J/L, depending on configuration and application constraints.
The CF-PP140 capacitor range is intended for demanding applications where thermal constraints, compactness, and reliability are critical. Typical use cases include unmanned aerial vehicles (UAVs), eVTOL aircraft, and heavy vehicles such as agricultural tractors, where power electronics are exposed to high temperatures and limited volume.
