Panasonic Industry Europe has introduced its new ECWFJ series of metallized polypropylene film capacitors, designed to provide a cost-efficient solution without compromising safety, durability, or reliable performance. Qualified to AEC-Q200 standards, the series is intended for industrial and automotive power electronics applications where components must withstand challenging operating conditions.
The ECWFJ capacitors offer strong moisture resistance, maintaining reliable performance at 40°C and 95% relative humidity for up to 1,000 hours. This makes them suitable for use in humid and demanding environments while keeping costs under control. The series can therefore support a wide range of industrial applications as well as automotive electronic systems.
Typical application areas include electric mobility systems such as DC/DC converters, on-board chargers and e-compressors, along with solar inverters and EV charging infrastructure. The series is also designed for use in industrial power supplies, LED lighting, smart meters and embedded power systems, where consistent electrical performance and durability are essential.
Technically, the ECWFJ series covers voltage ratings from 600V up to 1.100V DC. Capacitance values range from 1µF up to 12µF. The capacitors operate across a temperature range from -40°C up to +110°C, with the 1.000V variant rated up to 105°C. The devices are engineered to withstand thermal shock from -55°C up to 85°C over 1.000 cycles and can tolerate maximum ambient temperatures of up to 125°C for limited durations.
Panasonic’s proprietary patterned metallization with an integrated fuse mechanism helps ensure stable capacitance over the lifetime of the component and enhances overall system reliability. The design is complemented by a flame-retardant plastic enclosure and non-conductive resin, supporting compliance with UL and other regulatory standards. In addition, the capacitors are fully compliant with RoHS requirements.
