Additional Details:

The PHE431 series capacitors, including the PHE431SF5180J, use a metallized polypropylene film dielectric for high performance and reliability. The metallization process provides self-healing properties, allowing the capacitor to recover from minor overvoltage events, which extends its operational life. The capacitor is encapsulated in a flame-retardant epoxy resin coating for added protection. This particular model has a capacitance of 0.18 µF, a voltage rating of 900 VDC, and a capacitance tolerance of ±5%. It operates over a temperature range of -40°C to +105°C. The PHE431SF5180J is well-suited for use in power electronics, industrial equipment, and other applications where a stable and reliable capacitor is required.
