Murata unveils latest automotive-grade MLCCs

Murata has announced that is has begun volume production of two new multi-layer ceramic capacitors (MLCCs).

Each component exhibits low levels of equivalent series inductance (ESL) and is targeted at automotive implementation.

Supplied in a 0402 format (with 1.0 mm x 0.5 mm dimensions) and providing a 1 μF capacitance, the NFM15HC105D0G3 is said to be the world's smallest three-terminal low-ESL MLCC. This is complemented by the NFM18HC106D0G3, which has a 10 μF capacitance, making it the highest capacity three-terminal low-ESL MLCC in a 0603 (1.6 mm x 0.8 mm) form factor.

As the amount of electronic content being incorporated into automotive designs is rising dramatically, so there is a need for a greater number of electronic control units (ECUs) and the ramping up of processing resources which in turn need next-generation MLCCs to accompany them. These components must combine elevated capacitance figures and superior ESL characteristics with compact size and strong reliability, so that both performance demands and board space limitations can be met.

The new MLCCs utilise Murata's own thin-layer technology, as well the company’s expertise in high-precision lamination and advanced electrode construction. Consequently, the NFM15HC105D0G3 is claimed to occupy a volume that is as much as 60% smaller than competing MLCCs on the market.

Likewise, the NFM18HC106D0G3 has a capacitance that is approximately ten times higher than many MLCCs of a similar size.

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