WIMA MKS4-0.022MF-630V-10 Polyester Film Capacitor 0.022uF (22nF) 630V 10% Radial
WIMA MKS 4 Capacitors
WIMA's MKS 4 capacitors are produced with the proven box technology using solvent-resistant and flame-retardant plastic cases according to UL 94 V-0. The advantage of this method of construction, besides the improved mechanical stability of the component on the board, is the excellent electrical contact reliability.
In the case of metallized capacitors, thin layers of aluminum (approximately 0.03 µm) are vacuum-deposited on the insulating film as conducting electrodes. In the case of a breakdown, the short-circuit current causes the thin metal coating to evaporate around the point of failure and an insulating area is formed. The capacitor remains intact (self-healing). Due to their construction principle, metallized capacitors stand out for their very favorable capacitance/volume ratio.
By making use of ultra-thin film and appropriate manufacturing experience, it has been possible to achieve high capacitance values in very small box sizes.
