EMI suppression capacitors (MKP) X2 class
Very small dimensions
Self-healing properties
Plastic case, epoxy resin sealing (UL 94 V-0)
"Across the line" applications

Capacitors X class are designed for connecting directly across a mains supply, but should NOT be used in positions where failure of a capacitor would expose anybody to electric shock.

Self-healing properties
High stability of capacitance value
Applications
X2 class for interference suppression
"Across the line" applications
Severe ambient conditions
For connections in series with the mains
Capacitive power supply
Energy meters
