Self-extinguishing encapsulation. The
material is recognized according to
UL 94 V-0.
Very precise positioning of the leads in
relation to the case giving efficient
utilisation of PC board space.
Excellent self-healing properties.
Ensures long life even when subjected to
frequent overvoltages.
High dU/dt capability.
Good resistance to ionisation due to
impregnated dielectric.
The capacitors meet the most stringent
IEC humidity class, 56 days.
The impregnated paper ensures excellent
stability giving outstanding reliability
properties, especially in applications
having continuous operation.
