✔ RoHS Compliant  /  ✔ 0805  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• Power Supply Decoupling: The 4.7µF capacitance and 25V rating provide effective noise filtering for 1.8V–12V rails in portable electronics, while the 0805 package saves PCB space.
• Smoothing Circuits in IoT Modules: X7S dielectric ensures low capacitance drift under temperature fluctuations, making it reliable for wireless sensor nodes operating in harsh environments.
• Output Filtering in DC-DC Converters: The ±10% tolerance and stable performance at 25V suit low-ripple output stages in battery-powered devices like wearables.

Key Features & Advantages

• High Capacitance Density: Achieves 4.7µF in a compact 0805 case, enabling miniaturized designs without sacrificing decoupling performance.
• Wide Temperature Range: X7S dielectric supports -55°C to +125°C operation with only ±22% capacitance change, ideal for industrial and automotive-adjacent applications.
• Low ESR & ESL: Murata’s multilayer construction minimizes parasitic losses, improving high-frequency filtering efficiency in switching regulators.

Frequently Asked Questions

1. Q: What makes GRM219C71E475KE21L different from a standard X7R capacitor?
   A: While X7R offers ±15% change, X7S (used here) guarantees only ±22% change but over a broader rated temperature range, providing more stable performance under extreme heat or cold.
2. Q: Is GRM219C71E475KE21L RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free, meeting current environmental regulations.
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 from our extensive inventory.
