SABIC introduced its 5-micron ELCRES HTV150 dielectric film for high-temperature, high-voltage, professional-grade capacitor applications, like traction inverters for hybrid, plug-in hybrid, and battery electric vehicles.
This film, featuring high-heat performance up to 150 °C, surpasses the temperature and voltage capabilities of incumbent products. ELCRES HTV150 film can help support the transition from conventional semiconductors based on silicon (Si) to next-generation, wide-band-gap technologies based on silicon carbide (SiC), improving the efficiency of inverter modules.
ELCRES HTV150 dielectric film can support the design of high-voltage, high-temperature DC link power capacitors that can store large amounts of electrical energy for long periods without significant leakage of current or loss of charge. This technology offers potential advantages for capacitor applications, including excellent dielectric and insulative properties, as well as low loss at the high frequencies and high temperatures at which wide-band-gap semiconductors operate. The film offers high reliability that is critical for next-generation xEV. Based on internal testing, the film demonstrated a lifespan of 2,000 hours at 500V and 150 °C.
With an operating temperature range of -40 °C to 150 °C and high voltage performance, ELCRES HTV150 dielectric film is a candidate for demanding applications, such as power capacitors for the latest EV traction inverters and onboard chargers. The film can also be used for power capacitors in mass transportation, renewable energy, aerospace and motor drives and controls.
SABIC is currently collaborating with Shin-Etsu Polymer Co., Ltd. to produce ELCRES HTV150 film. SABIC will continue to develop thinner-gauge film to satisfy requirements for different voltages and higher energy density.
