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.
Example of design with 2 epoxide flat terminals
APPLICATIONS
