Ultra Stable X8R/X8L 150°C Dielectric Ceramic Caps KEMET Ultra Stable X8R and X8L +150°C Dielectric Ceramic Capacitors are high-temperature surface mount capacitors that are ideal in harsh environments such as Down Hole (oil exploration), automotive (under the hood), and aerospace. The KEMET X8L capacitors are available in case sizes EIA 0402, 0603, 0805, 1206, and 1210 while providing greater protection and superior flex performance over standard termination systems. The Ultra Stable X8R +150°C Dielectric Capacitors exhibit no capacitance loss when DC voltage is applied and is available in case sizes EIA 0402, 0603, 0805, 1206, 1210, and 1812. Product applications include harsh environments such as Down Hole (Oil Exploration), Automotive (Under Hood), Military, and Aerospace.
