KEMET C4AQNBU4550M1EJ Film Capacitor

The KEMET C4AQNBU4550M1EJ is a radial, metallized polypropylene film capacitor specifically engineered for demanding automotive DC link applications. Featuring a capacitance of 5.5µF, a 5% tolerance, and a robust 1000 VDC voltage rating, this capacitor delivers reliable performance in challenging environments. Its AEC-Q200 qualification ensures suitability for automotive standards. The capacitor's low dissipation factor (0.02% at 10 kHz and 25°C) and high insulation resistance (5.5 GOhms) contribute to efficient and stable operation. It is ideal for applications requiring high voltage and ripple current handling capabilities.
