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

Typical Applications & Why This Part Fits

• Power rail decoupling in portable devices: With 0.47 µF at 10 V in a tiny 0402 footprint, it smooths transient loads in smartphones and wearables without wasting board space.
• High-speed digital line filtering: The X7R material ensures capacitance remains stable across -55°C to +125°C, critical for suppressing noise on data buses.
• Battery-powered IoT sensors: Its low leakage and tight ±10% tolerance reduce energy loss and maintain consistent timing in low-power wake-up circuits.

Key Features & Advantages

• Compact 0402 form factor: Enables dense PCB layouts for miniaturized designs like hearing aids or module integration.
• Stable X7R dielectric: Delivers predictable capacitance over temperature and voltage, outperforming Y5V in reliability.
• Murata manufacturing precision: Guarantees low ESR and tight tolerance (±10%) for consistent batch-to-batch performance in production.
