Murata Starts Mass Production of High-Capacitance Automotive MLCCs

Why It Matters

Higher‑capacitance, smaller MLCCs enable OEMs to pack more advanced ADAS and power‑train functions into limited PCB space, lowering costs and improving vehicle reliability.

Key Takeaways

• Murata launches seven automotive‑grade MLCCs with higher capacitance.
• 100 µF achieved in 1206 package, previously required larger size.
• 2.2 µF now fits in 0201, enabling tighter PCB layouts.
• 1 µF power capacitor fits in 0402, reducing board space.
• Smaller, higher‑capacitance parts cut component count and energy use.

Pulse Analysis

The automotive sector is undergoing a rapid electronics renaissance as advanced driver‑assistance systems (ADAS) and fully autonomous functions become standard. Each new sensor, processor, and communication module adds to the vehicle’s electronic control unit (ECU) count, driving demand for components that can store more charge without consuming precious PCB real estate. Multilayer ceramic capacitors (MLCCs) have traditionally balanced capacitance, voltage rating, and size, but the surge in high‑speed digital and power‑train applications is stretching those trade‑offs to their limits.

Murata’s new automotive‑grade lineup tackles that dilemma by pushing material science and internal stack geometry to new extremes. The company reports a 100 µF capacitor fitting into a 1206 package—a size that previously accommodated only a fraction of that charge—while a 2.2 µF part now occupies the ultra‑compact 0201 footprint. For power‑rail filtering, a 1 µF device is available in 0402, delivering the voltage handling needed for 25 V circuits. These density gains translate into fewer discrete parts per board, simplifying routing and improving overall system stability.

The timing aligns with OEMs accelerating the rollout of Level‑3 and Level‑4 autonomous platforms, where every millimeter of board space carries a cost premium. By consolidating capacitance functions, Murata’s parts can lower bill‑of‑materials expenses and reduce assembly energy consumption—an increasingly important metric for sustainability‑focused manufacturers. Competitors such as TDK and AVX are also expanding high‑density MLCC portfolios, but Murata’s early mass‑production start gives it a supply‑chain advantage. Analysts expect the new components to become a standard building block in next‑generation vehicle architectures.
