The B3202x series varies up to 1µF with a Y2 safety classification, 300 VAC rated voltage, and 100ºC temperature range. Note that 300 VAC is the maximum rating allowed by IEC for Y2. In the event that a higher safety requirement is requested, the X1 EPCOS series (with 4 kV impulse test), can also be used. There are two series: one rated at 330 VAC up to 6.8µF, and other rated at 440 VAC up to 1µF.
