Film capacitors ensure longer service life in harsh environment conditions

06-09-2019 | Vishay | Passives

Vishay Intertechnology offers three new series of X1, X2, and Y2 EMI suppression film capacitors for standard across the line and line bypass applications. Created to satisfy the most rigorous demands for robustness against humidity, the new F340 EMI suppression family is certified to IEC 60384-14: 2013 ed. 4 / AMD1: 2016 grade IIIB: 'High Robustness Under High Humidity'.

To comply with the humidity grading system the devices withstand THB testing of 85C, 85% relative humidity for 1000 hours while biased at the rated AC voltage with high stability on capacitance, dissipation factor, and insulation resistance. This translates into longer service life under harsh application conditions for industrial and automotive power electronics, such as renewable energy inverters, battery chargers, motor drives, and UPS.

The F340X1 is intended for a rated voltage of 480VAC. It provides a wide capacitance range from 0.22µF to 8.2µF while withstanding operation voltages up to 530VAC to ensure compliance with permissible voltage variations on three-phase mains. The F340X2 offers a rated voltage of 305VAC and gives a capacitance range from 1µF to 20µF, with high ripple current capabilities up to 18A at 10kHz. Also featuring a rated voltage of 305VAC, the F340Y2 is qualified in accordance with AEC-Q200, Automotive Grade and offers a capacitance range from 0.01µF to 1µF.

The entire family is certified in accordance with EN, UL and CQC for Safety and Humidity Robustness. The capacitors provide lead pitches of 15mm, 22.5mm, 27.5mm, 37.5mm, and 52.5mm. Their encapsulation consists of a flame-retardant UL-class 94V-0 plastic case and epoxy resin sealing. All three series are lead (Pb)-free and RoHS-compliant; and the devices are also halogen-free and Vishay Green.
