KEMET PHE850 Y2 capacitors have worldwide safety agency approvals and a wide capacitance range. They offer superior self-healing properties in combination with a small size and competitive price. Self-healing is the protection method so that if a voltage surge punctures the dielectric, the heat generated at the point of failure melts the surrounding metal and insulates the area of the breakdown. KEMET PHE850 Y2 capacitors are rated 300VAC and are dielectric withstand tested with 5,000VDC and 2,500VAC. They are also quite stable over the temperature range of -55°C to +110°C, having only a slightly negative temperature coefficient.
