✔ RoHS Compliant / ✔ 0402 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Power Supply Decoupling: The 10V rating and 0.047μF capacitance make it ideal for smoothing rail noise in low-voltage digital circuits, such as MCU VCC bypassing.
- Signal Coupling/Filtering: X7R’s stable capacitance over -55°C to +125°C ensures reliable AC coupling in sensor interfaces and audio paths.
- IoT Modules: The compact 0402 package fits densely populated PCBs in wireless modules, wearables, and smart sensors where board space is critical.
Key Features & Advantages
- X7R Dielectric: Offers ±15% capacitance change over temperature, balancing volumetric efficiency with moderate stability for general-purpose use.
- 10V Voltage Rating: Provides adequate headroom for 3.3V and 5V logic lines, reducing derating risks in modern low-power designs.
- Nickel Barrier Termination: Lead-free and compatible with reflow soldering, ensuring reliable solder joint formation and long-term mechanical strength.
