Film Capacitors: Compact and Overvoltage Protected

The company introduced a new line of EPCOS metallized polypropylene film AC (MKP AC) capacitors B33331V* for use in filters. This family of components has a rated voltage of 460 VRMS, corresponding to a peak voltage of 650 V and a capacitance range of 2 μF to 50 μF. Capacitor shell and top are made of aluminum alloy material, the overall structure is extremely solid. In addition, the overall size of the capacitor is particularly compact, only 30 mm x 55 mm to 50 mm x 100 mm (diameter x height), depending on the capacitor model. The new capacitors have excellent reliability and reliable operation even under harsh environmental conditions. In addition, this series of products is also verified by the relevant temperature, humidity, and bias voltage (THB) tests. When rated voltage is applied under the test conditions of a temperature of 85°C and a relative humidity of 85%, the capacitor can continue to operate for 1,000 hours.

Capacitors meet IEC 61071 standards and have an expected life of more than 100,000 hours. Capacitor with CE mark, the overall diameter is greater than 40 mm, passed UL certification, the flame retardant rating of the connector meets the requirements of UL 94 V0 standard. The capacitor is also integrated with an overpressure separation safety device that effectively isolates both terminals and windings once the enclosure is subjected to overvoltage due to overload. New types of capacitors are widely used in various fields, such as output filters for photovoltaic inverters, inverters, and uninterruptible power supplies.
