KEMET Commercial & Automotive High Temp 150°C Capacitors
KEMET Power Solutions (KPS) Commercial and Automotive High-Temperature (+150°C) Stacked Capacitors utilize a proprietary lead-frame technology to vertically stack one or two multilayer ceramic chip capacitors (MLCCs) into a single compact surface-mount package. The attached lead frame mechanically isolates the capacitor(s) from the printed circuit board, delivering advanced mechanical and thermal stress performance. Isolation also addresses concerns for audible, microphonic noise that might occur when a bias voltage is applied. A two-chip stack offers up to double the capacitance in the same or smaller design footprint compared to traditional surface-mount MLCC devices. Providing up to 10mm of board flex capability, the KPS capacitors are environmentally friendly and RoHS compliant.
Combined with X8L dielectric, these KEMET devices are capable of reliable operation up to +150°C and are well suited for high-temperature filtering, bypass, and decoupling applications. X8L exhibits a predictable change in capacitance with respect to time and voltage while boasting 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.
