High Temperature Chip
X8R
Description
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 200V and capacitance values from 1nF 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.
