Special Characteristics

MKP 10
FKP 4
FKP 1

Fly-back (e.g. monitors, TV)

–	current flows from deflection coil to fly-back capacitor
–	electron beam is rapidly shifted from right to left side of screen

Pulse and current rating: high (MKP 10), very high (FKP 4) or extremely high (FKP 1)
Self-healing capability -> high withstanding voltage, outstanding reliability
Very low dissipation factor
High insulation resistance

S-correction (smoothing)

–	current flows from C_L through trafo deflection coils to C_S
–	C_S is smoothing pulsating DC-voltage

–	Low dissipation factor
–	Good pulse rise time

Energy storage (e.g. ballasts)

–	capacitor is charged to a high voltage, stores the energy and then releases it in short time

–	High pulse rise time
–	High (surge) current carrying capacity
–	High insulation resistance

Oscillating circuit Resonant system (LC):

–	AC voltage oscillates at resonant frequency
–	see also filter applications

–	Low dissipation factor
–	Stable capacitance (please refer to technical data)

Snubbing (e.g. relay)

–	capacitor attenuates over-voltage peaks by high current switching

–	Low dissipation factor
–	High pulse rise time (please refer to technical data)
