KPS-MCL Low-Loss +200°C SMPS Stacks (Industrial)

KEMET KPS-MCL Low-Loss, High Temperature (+200°C) SMPS Stacks combine a robust and proprietary C0G/NPO base metal electrode (BME) dielectric system with a durable lead frame technology for high-temperature and high-power switch power supply (SMPS) applications. These stacks are designed to withstand harsh industrial environments, such as down-hole oil exploration and automotive or avionics engine compartment circuitry. KEMET KPS-MCL Low-Loss +200°C SMPS Stacks are constructed with large-chip multilayer ceramic capacitors (MLCCs) that are vertically stacked and secured to a lead-frame termination system using a high melting point (HMP) solder alloy. The vertical stacking in the lead frame provides lower ESR (low loss) and thermal resistance, which translates to high ripple current capability. The lead frame isolates the MLCCs from the printed circuit board (PCB) while establishing a parallel circuit configuration.
