Automotive-Grade MLCCs Shrink to the Smallest Form Factor Yet
Murata rolled out its LCC series of automotive-grade multi-layer ceramic capacitors (MLCC). The new passives feature a reversed termination to reduce equivalent-series inductance (ESL) inside the MLCC. They’re housed in a uniquely thin package with a 0.18-mm profile. The dimensions of the passive components are 0.5 × 1.0 mm for a 1-µF capacitance rating, giving them the smallest form factor on the market, said Murata.
The LLC series uses Murata’s thin-layer forming and high-precision lamination technology and other advanced material processing techniques to deliver a 20% reduction in height relative to existing caps. That gives you the ability to fit them more easily on the backside of circuit boards, even among solder-ball terminations. The parts can be placed in the optimal position for the decoupling of processor power rails, preferably close to the die. That, in turn, reduces the number of capacitors required in a system, saving cost and increasing reliability.
Along with improvements in equivalent-series resistance (ESR), the reduction in ESL curtails high-frequency impedance of the capacitors. That gives the LLC series a performance boost when paired with the processors at the heart of advanced driver-assistance systems (ADAS). The new automotive-grade LLC series meets AEC-Q200 requirements.
