Encapsulation of WIMA Capacitors



Both, SMD and through-hole WIMA DC capacitors are produced with the proven box technology, showing the following substantial advantages in comparison with non-encapsulated, moulded or dipped capacitor versions: Safe protection of the capacitor element against the mechanical stresses which occur during processing and operation. No danger of delamination, internal cracks or tearing away of the contacts due to similar expansion coefficient and the elasticity of the construction. Excellent self-healing properties of metallized WIMA capacitors due to pressure free layers in the winding element. Flame retardant plastic case in accordance with UL 94 V-0. Clearly defined dimensions allows for close placement and exact setting of parts on PC-boards. Even larger parts are easily robotically insertable. Easy second source because of standardized box size.
