X8R High Temperature Capacitors — up to 150°C
The X8R dielectric will operate from -55°C to +150°C, with a maximum capacitance change 15ꢀ (without applied voltage).
The devices are available in sizes 0805 to 2225, with voltage ranges from 25V to 3kV and capacitance values from 100pF to 2.2μF.
The capacitors have been developed by Knowles Precision Devices to meet demand from various applications in the automotive and
industrial markets and in other electronic equipment exposed to high temperatures. The increased use of electronics in automotive
“under the hood” applications has created demand for this product range.
The X8R range incorporates a specially formulated termination with a nickel barrier finish that has been designed to enhance the
mechanical performance of these SMD chip capacitors in harsh environments typically present in automotive applications.
