KEMET C300C X8L Dielectric Goldmax Conformally Coated Radial Through-Hole Ceramic Capacitors offer a +150°C maximum operating temperature and are considered "general purpose high temperature" devices. These MLCCs are fixed, ceramic dielectric capacitors that are ideal for high temperature bypass and decoupling applications or frequency discriminating circuits, where Q and stability of capacitance characteristics are not critical. X8L exhibits a predictable change in capacitance with respect to time and voltage, and boasts a minimal change in capacitance with reference to ambient temperature up to +125°C. Beyond +125°C X8L displays a wider variation in capacitance. Capacitance change is limited to ±15% from −55°C to +125°C and +15, −40% from +125°C to +150°C.
