The CF-PP140 series comprises a wide range of standard components designed for applications requiring high energy density in a compact form factor. It supports operating voltages from 450 V to 1500 V, offers an energy density of up to 250 J/L, and raises the operating temperature of the polypropylene to 140 °C. These capacitors feature a standard form factor that facilitates system integration, making them suitable for space-constrained electronic architectures.
Furthermore, Exxelia offers a higher level of integration by combining a CF-PP140 and an Exxelia SVM busbar in fully customized "Power Block" capacitors. These bespoke blocks can meet specific customer size and electrical performance requirements, even in the most demanding applications.
The CF-PP140 product series offers exceptional operating capability at temperatures up to 140°C, compared to the typical 105°C of similar polypropylene (PP) film capacitors, along with an approximately 30% increase in energy density compared to competing solutions. In custom designs, energy density can reach 250 J/L, depending on the configuration and application constraints.
The CF-PP140 capacitor range is designed 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 space limitations.
With the CF-PP140 range, Exxelia offers:
● Film capacitor solutions with operating temperatures up to 140°C for mission-critical applications
● High energy density in compact packages, up to 250 J/L, to suit space-constrained mechanical environments
● Customizable form factors and integration options to meet specific application constraints and reduce installation time
● Self-Healing technology: incorporates advanced SH (Self-Healing) properties that eliminate localized insulation failures, ensuring continuous operation and extended service life.
● SMD and DIL connections available upon request
Howdoes CF-PP140 (PP-HT) compare to other dielectrics?
CF-PP140, based on high-temperature polypropylene (PP-HT), sits between standard polypropylene and high-temperature polymers. It extends the operating range of PP up to 140 °C while maintaining a high energy density (up to 250 J/L). Compared to PET or PPS, CF-PP140 offers higher energy density at elevated temperatures and, compared to PEI or PTFE, provides a more compact solution with significantly higher volumetric efficiency. This balance makes CF-PP140 particularly suitable for power electronics applications with both space and temperature constraints.
