Typical Applications & Why This Part Fits

• Power Rail Decoupling in IoT Modules: The 47µF capacitance handles transient current spikes effectively, while the compact 1210 footprint makes it ideal for densely populated PCBs in wireless sensors and edge computing devices.
• DC/DC Converter Output Filtering: With a 10V rating and X6S dielectric, this MLCC provides stable bulk capacitance across -55°C to +105°C, ensuring clean power delivery in industrial converters.
• Battery Line Smoothing in Wearables: The ±10% tolerance and low ESR characteristics of the X6S material minimize voltage ripple, extending battery life in portable health monitors and smart glasses.

Key Features & Advantages

• High Capacitance Density: 47µF in a 1210 package saves board space while providing sufficient energy storage for low-voltage power management.
• Wide Temperature Stability: X6S dielectric offers only ±22% capacitance change over the full -55°C to +105°C range, outperforming standard X5R in thermal cycling environments.
• Precise Tolerance Control: The ±10% tolerance enables tighter design margins for voltage regulator feedback loops, reducing output ripple without over-specifying.
