Film capacitors target vehicle on-board charging
Panasonic Industry Europe has launched a range of Metallized Polypropylene Film Capacitors for on-board charging and powertrain electronics in automotive designs.

The AEC-Q200 qualified ECWFG series operates from -40°C to 110°C with a rated voltage of 630V DC and a nominal capacitance range of 1.0µF to 4.7µF. This enables it to cater to most of the high frequency and high current circuit designs. 

The ECWFG series has a high humidity resistance of 85°C, 85% RH, 500V DC over 1000 hours, high thermal shock resistance from -55°C up to  85°C over 1000 cycles and a high temperature load test at 125°C and 450V DC over 1000 hours. A flame-retardant plastic case and non-combustible resin further reduce the risk of flammability. The products are fully RoHS compliant.

Panasonic’s original in-house patterned metallization process achieves a very stable capacitance level over the capacitor’s lifetime and therefore guarantees a high reliability for the application. The patterns serve as a fuse mechanism function that prevents catastrophic short mode failure.

The capacitors can be used for Power Factor Correction or smoothing, making them suitable for applications including DC-DC, DC-AC and AC-DC converters, input and output filtering, or snubber for industrial power supply, EV / PHEV charger and inverter applications for Renewable Energy.
