✔ RoHS Compliant  /  ✔ 0402  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• Power decoupling in portable devices: The 4.7µF capacitance at 10V provides effective ripple suppression for battery-powered circuits, while the 0402 package suits tight PCB layouts.
• Signal filtering in IoT modules: X6T dielectric ensures stable capacitance across a wide temperature range, maintaining filter accuracy for wireless communication links.
• Output smoothing in compact DC-DC converters: The 4.7µF value and ±20% tolerance offer a cost-effective solution for rail stabilization in low-profile power stages.

Key Features & Advantages

• X6T Dielectric: Provides enhanced temperature stability compared to X5R, ensuring reliable performance from -55°C to +105°C.
• 0402 Miniature Package: Enables high-density mounting for miniaturized designs in wearables, sensors, and mobile devices.
• ±20% Tolerance: Balances precision with cost efficiency, ideal for decoupling and bulk bypass applications where tight tolerance is not critical.

Frequently Asked Questions
