Safety Capacitor X2 1uF 275V P22

High-Performance EMI Suppression and Safety Protection

The 1uF 275VAC X2 Safety Capacitor is an essential passive component designed for across-the-line electromagnetic interference (EMI) and radio frequency interference (RFI) suppression in AC power line applications. Constructed with premium metallized polypropylene film (MKP), this capacitor provides reliable high-frequency noise filtering while offering excellent self-healing properties that prevent catastrophic dielectric breakdown under transient voltage surges.

Robust MKP Construction and Self-Healing Mechanism

Featuring a non-inductive metallized polypropylene dielectric housed in a flame-retardant plastic case filled with UL 94V-0 compliant epoxy resin, this safety capacitor is built for demanding operating environments. If an overvoltage spike breaches the dielectric layer, the thin metallization surrounding the fault vaporizes instantly, isolating the shorted point and restoring regular capacitive function. This self-healing ability ensures long-term operational integrity and protection against high-voltage line transients.

Safety Compliance and Across-the-Line Applications

Classified as an X2 safety capacitor, this component is rated for direct line-to-neutral connection across AC mains supplies up to 275VAC continuous working voltage. In compliance with international safety standards such as IEC 60384-14, UL 60384-14, and ENEC, it is engineered to fail safely by creating a controlled short circuit during severe breakdown events, safely triggering upstream line fuses to prevent electrical shock or fire hazards.

Wide-Ranging Industrial and Consumer Applications

With a standard 22.5mm lead pitch (P22), this 1uF capacitor is ideal for insertion into switch-mode power supplies (SMPS), LED drivers, battery chargers, solar inverters, motor run circuits, and household appliances including washing machines, refrigerators, and televisions. It serves as an optimal front-end filter directly behind the AC power inlet to clean incoming power signals and ensure electromagnetic compatibility (EMC) compliance for modern electronic assemblies.
