Murata Stacks 100µF into 0201: The Race to Shrink Everything

Imagine fitting a water tank into a matchbox. Now imagine that water tank needs to survive temperatures from -55°C to +125°C, vibrate for 15 years, and cost less than a dollar.

That’s the MLCC challenge in one sentence. And Murata just threw down the gauntlet with seven new AEC-Q200 qualified MLCCs that push the limits of what’s possible in every dimension.

The Headline Numbers

• 1206 @ 100µF: Industry’s first. Previous record was ~47µF. Same footprint, double the capacitance.
• 0201 @ 100µF: Jumps from traditional ceiling of 1-2.2µF. That’s a 45-100x improvement in the same package.
• 0402 @ 1µF: Outpaces old 0603 packages by shrinking PCB area by ~61%.

Why This Matters for ADAS

Advanced Driver Assistance Systems need decoupling capacitors placed extremely close to processing chips. Every square millimeter matters when you’re routing high-speed signals between radar modules, sensor fusion processors, and power management ICs.

Murata’s five low-voltage (2.5-4V) parts are specifically targeting the bypass capacitor role around ADAS silicon. The two 25V parts handle automotive power bus filtering. It’s a complete power chain solution in seven SKUs.

The 1206 Story

Before today, achieving 100µF in a 1206 (3.2×1.6mm) required either larger dies or sacrificing voltage rating. Murata’s new parts maintain full voltage rating while doubling the capacitance ceiling. Designers can either shrink their boards or add more functionality in the same space.

36% PCB area reduction isn’t a marketing number—it’s a real trade-off decision that automotive tier-ones can now make with confidence, backed by AEC-Q200 qualification.
