The X8R dielectric will operate from -55°C to +150°C,with a maximum capacitance change ±15% (without applied voltage). The devices are available in sizes 0805 to 2225, with voltage ranges from 25V to 3kV and capacitance values from 270pF to 1.8μF. The capacitors have been developed by Syfer 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. For information, X8R dielectric contains lead within the ceramic and parts rated less than 250Vdc are not compliant with the EU 2011/65/EU RoHS directive.
