What is KRM55WR7YA476MH01L MLCC?

The KRM55WR7YA476MH01L is a high‑voltage multilayer ceramic capacitor (MLCC) from Murata. Key specs include 47µF capacitance, 35V voltage rating, X7R dielectric, and ±20% tolerance. Fully RoHS compliant, it delivers stable performance and reliable filtering in space‑constrained power designs.

✔ RoHS Compliant  /  ✔ SMD  /  ✔ Murata Quality  /  ✔ Long‑Term Supply

Typical Applications & Why This Part Fits

• DC‑DC Converter Output Filtering: The 47µF capacitance combined with 35V voltage rating provides low‑impedance bulk decoupling, reducing ripple in industrial and telecom power stages.
• Automotive ECU Power Supplies: X7R dielectric ensures stable capacitance over –55°C to +125°C, while the ±20% tolerance accommodates cost‑effective manufacturing in engine control units.
• Base Station Power Distribution: High capacitance density in an SMD package supports tight board layouts, and the 35V rating offers headroom for 24V bus lines.

Key Features & Advantages

• 47µF in Standard SMD Package: Achieves high capacitance without increasing footprint, enabling miniaturized power designs.
• 35V DC Voltage Rating: Provides a robust margin over typical 12V or 24V rails, increasing system reliability against transients.
• X7R Temperature Stability: Capacitance change within ±15% over the full operating range ensures consistent filtering performance under temperature extremes.

Frequently Asked Questions
