Three new series of X1, X2, and Y2 electromagnetic interference (EMI) suppression film capacitors have been unveiled by Vishay Intertechnology. These capacitors will come in handy for standard across the line and line bypass applications. This new F340 EMI suppression family is certified to IEC 60384-14: 2013 ed. 4 / AMD1: 2016 grade IIIB, meaning that capacitors under this family can survive adverse humid conditions.
Further, complying with humidity grading system defined under IEC 60384-14: 2013 ed. 4 / AMD1: 2016 grade IIIB, these components can withstand temperature humidity bias (THB) testing of 85 °C, 85 % relative humidity for 1000 hours, while biased at the rated AC voltage with high stability on capacitance, dissipation factor, and insulation resistance. This certification translates into a longer life span, even in harsh application conditions for industrial and automotive power electronics. A few of these applications include battery chargers, renewable energy inverters, motor drives, and UPS.
The capacitor F340X1 is designed for a rated voltage of 480 VAC, offering a broad capacitance range from 0.22 µF to 8.2 µF. It can withstand operation voltages up to 530 VAC ensuring adherence with permitted voltage variations on three-phase mains. Whereas, the F340X2 has a rated voltage of 305 VAC and provides a capacitance range from 1 µF to 20 µF, with high ripple current capabilities up to 18 A at 10 kHz. Finally, the F340Y2 complies with AEC-Q200 standard while providing an automotive Grade capacitance range from 0.01 µF to 1 µF. It is has a voltage rating of 305 VAC, similar to that of F340X2.
All of the above-mentioned series are lead (Pb)-free and RoHS-compliant further, F340X1 480VAC and F340X2 305VAC are even halogen-free and Vishay Green devices. The lead pitches offered by these capacitors are 15 mm, 22.5 mm, 27.5 mm, 37.5 mm and 52.5 mm. Talking further about encapsulation, these are protected by a flame-retardant UL-class 94 V-0 plastic case and epoxy resin sealing. Finally, the F340 family is certified in accordance with EN, UL and CQC, citing safety and humidity issues.
