MLCC KRM55QR71J106KH01K

What is KRM55QR71J106KH01K MLCC?

The KRM55QR71J106KH01K is a multilayer ceramic capacitor (MLCC) from Murata. Key specs include 10µF capacitance, 63V rating, X7R dielectric, and ±10% tolerance. RoHS compliant, it is designed for stable filtering and decoupling in space-constrained, high-voltage circuits.

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

Typical Applications & Why This Part Fits

• Power Supply Output Filtering: With its 63V rating and 10µF capacitance in X7R, the KRM55QR71J106KH01K smooths ripple on DC-DC converter rails while tolerating high bias voltage without excessive derating.
• Automotive ECU Power Lines: The X7R dielectric ensures stable capacitance over a -55°C to +125°C temperature range, meeting harsh operating conditions in engine control units requiring 63V bulk decoupling.
• Industrial Sensor Modules: ±10% tolerance provides reliable performance in 24V industrial bus systems, where this MLCC absorbs switching noise from nearby motors within a compact SMD footprint.

Key Features & Advantages

• High Voltage Handling (63V): Enables direct use on 48V bus rails and 24V industrial supplies, eliminating the need for series stacking and simplifying board layout.
• X7R Temperature Stability: Capacitance change within ±15% across -55°C to +125°C ensures consistent circuit behavior in thermal cycling environments.
• Compact SMD Construction: Surface-mount packaging supports automated pick-and-place assembly and reduces parasitic inductance for high-frequency decoupling.

Frequently Asked Questions

1. Q: What makes KRM55QR71J106KH01K different from a standard 10µF MLCC?
   A: Its 63V voltage rating is significantly higher than typical 10µF X7R parts (usually 16V-50V), making it suitable for applications requiring a safety margin on higher-voltage rails.
2. Q: Is KRM55QR71J106KH01K RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free.
3. Q: What is the MOQ? Can we get small batches?
   A: We support small batch orders and full BOM kitting at SZYY, including fast prototyping supply and flexible lot sizes for early-stage builds.
