Solid tantalum molded chip caps offer low DCL of 0.005CV and high energy density

Vishay introduced a new series of Tantamount surface-mount solid tantalum molded chip capacitors designed specifically for electronic detonation systems. Combining a robust mechanical design with low leakage current (DCL) and stringent testing specifications, Vishay Sprague TX3 series devices deliver enhanced performance and reliability over commercial tantalum capacitors and MLCCs. With low DCL values of 0.005CV — and the high energy density of tantalum compared to other capacitive technology — the capacitors released today deliver more energy to ensure proper ignition. This makes them ideal for remote detonation systems with reliable discharge requirements in mining and demolition applications. The devices’ tantalum anode technology, combined with Vishay’s best in class dielectric formation, ensures stable electric performance in these harsh environments. To ensure reliability, TX3 series capacitors are tested to more stringent criteria than standard commercial offerings. Each part is 100 % surge current tested using standard screening methods, and undergoes two additional screenings for key electrical characteristics to eliminate lot to lot variations. Providing a robust solution, the devices’ capacitive element and lead frame are encapsulated by hard plastic resin. Compared to MLCCs, they offer higher shock (100 g) and vibration (20 g) capabilities in accordance with ...
