NFM18HC series capacitors provide a three terminal multilayer ceramic capacitor in the company’s smallest 1.6 x 0.8 mm package (previous product was 2.0 x 1.2 mm). It conforms to AEC-Q200 for automobile applications, making an important contribution to further size reduction and tighter density for automotive electronics.
The three terminal multilayer ceramic capacitor has a smaller equivalent series inductance (ESL) than conventional two terminal multilayer ceramic capacitors, thus reducing the overall impedance. This lowers the number of capacitors that need to be used for higher frequency decoupling which frees up board space.
Similar caps have wide adoption for smartphones and other devices where compactness and high density are needed for high-speed processors. The use of three terminal multilayer ceramic capacitors in the automotive market has, Murata concludes, surged recently for ADAS, preventive safety systems, and in-vehicle infotainment (IVI).
