High Voltage
L and J Leaded Ceramic Capacitor
SM Series
1. Silver plated copper alloy terminal for easy soldering.
2. Mounting tabs are designed to minimize the effect of thermal
stress introduced by the differences in coefficient of thermal
expansion between the capacitor and the mounting surface.
3. Low ESR.
4. High current discharge capability.
5. Group A and B screening per MIL-PRF-49467 available .
6. Standard lead configuration is 'B'.(J) If lead configuration is
left out of part number the lead style is assumed to be 'B'.
