Automotive MLCC features reversed termination for low ESL

Electronics Power Supply / Management automotive capacitors MLCC Murata

MURATA LLC series multi-layer ceramic capacitors for automotive applications features a reversed termination for low ESL and come in a 0.18mm profile package, and a footprint of 0.5 x 1.0mm for 1µF capacitance. Product series uses firm’s proprietary thin-layer forming and high-precision lamination technology, along with advanced material atomization and homogenization techniques to achieve about 20% reduction in component height compared with existing parts. This opens up the potential to more-easily fit the capacitors on the back-side of circuit boards, even amongst solder ball terminations, locating the parts in optimum positions for decoupling of processor power rails, close to the die. This in turn allows fewer capacitors to be used, saving cost, and increasing system reliability. The automotive-grade device complies with AEC-Q200 requirements, passing the 1000 temperature cycle test and temperature/humidity endurance test of 85°C at 80-85% humidity for 1000 hours.
