DISFIM Products

For Energy Storage and Discharge Applications

Based on the CONTROLLED SELF HEALING technology,

AVX offers impregnated capacitors, named DISFIM, which

are ideal for discharge applications.

With the controlled self-healing technology, the capacitance

of the DISFIM is divided into several million elementary

capacitances. The weak points in the dielectric are insulated

and the capacitor continues to work without any short-circuit

or risk of explosion.

DISFIM capacitors may represent more than 10,000 square

meters.

Only some square millimeters of active surface are lost for

every self-healing action.

Over the life of the capacitor, the capacitance gradually

decreases.

The capacitor is usually designed to lose less than 5% of its

initial capacitance during its whole lifetime.

APPLICATIONS

Power laser

Electromagnetic and ETC guns

High voltage supplies

Marx generators

Cable failure detection

Welding machine

Custom design is the rule as applications and

operating conditions are various.
