Compared to other applications, a medical implant is a rather benign environment for a capacitor; it’s temperature-controlled with a relatively low voltage. That being said, the success of a capacitor in a medical implant relies heavily on manufacturing components to avoid failures and the know-how to screen for any production discrepancies. As the reliability grade of a component progresses, more screening and testing is required to ensure that only the most robust parts make it to the finished product.
