True fail open tantalum capacitor offers reliability benefits for filtering applications

January 24, 2013 // By Paul Buckley
KEMET has introduced the T496 Hi-Rel Fused Commercial-Off-the-Shelf (COTS) MnO2 Series of tantalum surface mount capacitors.

The devices are ideal for use in high reliability applications where a capacitor short will disrupt the overall performance of the system. The internal fuse in the capacitor results in a fail open condition.

The T496 Hi-Rel Fused COTS MnO2 Series is available in DLA (DSCC) Drawing 04053 and can be ordered with a variety of options including surge current testing, Weibull Grading, termination options, and various ESR levels. A customizable testing and screening protocol is available upon customer request.      

Applications include decoupling and filtering in computing, telecommunication, defense, and industrial end applications requiring a built-in fuse capability. This includes filtering for point of load and switch mode power supplies.      

The devices complement KEMET's T493, T497, T513, T540, T541, and T543 series of COTS capacitors.
