A fused electrolytic capacitor assembly that offers improved performance
characteristics in a convenient and space-saving package is provided.
More specifically, the fused electrolytic capacitor assembly contains an
electrolytic capacitor element and a surface mount fuse that are
contained within a case and connected to a common anode termination.
During initial production, the electrolytic capacitor element and fuse
are connected to the anode termination so that the fuse is bypassed
during testing of the individual capacitor element. After testing, the
anode termination may be cropped so that the fuse and capacitor element
become connected in series. Thus, during use, the fuse will disintegrate
in response to an excessive current resulting from a short circuit
discharge, which breaks the electrical connection between the capacitor
element and limits the likelihood of fire or other damage remaining
circuit elements.
