"automotive" MLCCs are constructed like this internally. But they cost well more than twice as much as the non-automotive part, so you might as well put them in series in your circuit. Remember that capacitors in series are inverse-of-sum-of-inverses, like resistors in parallel. But if exact capacitance values are important to your circuit you've already gone astray with high-dielectric MLCCs. Automotive and soft-termination caps are expensive and hard to source. At the end of the day, the humble through-hole capacitor starts looking pretty attractive. If you're just hacking stuff together, you can try tenting two capacitors together to put them in series on pads made for one capacitor. Not a very robust construction technique. --=20 Regards, Mark markrages@gmail --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
