New benchmarks in capacitance with latest automotive-grade MLCCs

Murata has started volume production of two new MLCCs. Each of these components displays low levels of ESL and is aimed at automotive implementation. Supplied in a 0402 format (with 1mm x 0.5mm dimensions) and giving a 1μF capacitance, the NFM15HC105D0G3 is claimed to be the world's smallest three-terminal low-ESL MLCC. This is complemented by the NFM18HC106D0G3, which offers a 10μF capacitance, making it the highest capacity three-terminal low-ESL MLCC in a 0603 (1.6mm x 0.8mm) form factor.

The volume of electronic content being consolidated into automobile designs is increasing dramatically, as ADAS implementations become more common and higher levels of vehicle autonomy begin to develop. This is appearing in the utilisation of a greater number of ECUs and the ramping up of processing resources which in turn require next-generation MLCCs to accompany them. These components need to combine elevated capacitance figures and higher ESL characteristics with small size and robust reliability so that both performance demands and board space constraints can be answered accordingly.

The new MLCCs utilise the company's own proprietary thin-layer technology, as well it’s expertise in high-precision lamination and advanced electrode construction. As a consequence, the NFM15HC105D0G3 holds a volume that is as much as 60% smaller than competing MLCCs on the market. Likewise, the NFM18HC106D0G3 has a capacitance that is almost ten times higher than many MLCCs of comparable size.

Fully compliant with AEC-Q200 standards, these components support an -55C to +125C operational temperature range. Both have a 2A current rating.
