New “Open Mode” Extended Cap Values Available in a 100 Volt Rated SMD MLCC in X7R dielectric
Several new capacitance values have been added to KEMET’s 100 volt rated “Open Mode/ Fail Safe” surface mount multilayer ceramic capacitor (MLCC) product line in X7R dielectric. Capacitance values have been extended in EIA 0805, 1206, and 1210 case with new values ranging from .047 microfarads to 1.0 microfarads in tolerances of K (±10%) and M (±20%). Driven by demands for a more robust and reliable component, the “Open Mode” capacitor was designed for critical applications where higher operating temperatures and mechanical stress are a concern. These components meet the requirements of the Automotive Electronics Council's AEC-Q200-Rev. C and are widely used in automotive circuits as well as power supplies (input and output filters) and general electronic applications. They are also RoHS compliant, with 100% pure matte tin-plated terminations for excellent solderability.
The “Open Mode” capacitor greatly reduces the likelihood of a low-IR or short circuit condition in a board flex situation. When flexed to failure, KEMET's "Open-Mode" capacitor may experience a drop in capacitance but a short is unlikely because a crack will not typically cross opposing electrodes. Since there won't be any current leakage associated with a typical "Open-Mode" flex crack there is no localized heating and, therefore, no chance for a catastrophic and potentially costly failure event.
The operating temperature range of the X7R dielectric capacitor is between -55°C and +125°C, with zero bias capacitance shift limited to ±15% over that range.
All parts are environmentally friendly, in compliance with RoHS legislation and are capable of Pb-free reflow profiles.
