✔ RoHS Compliant / ✔ 0603 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- DC-DC Converter Output Filtering: The 4.7µF capacitance at 10V provides effective ripple smoothing and decoupling for power rail stability in portable devices.
- Wireless Communication Modules: X6S dielectric offers stable capacitance across -55°C to +105°C, ensuring reliable RF bypassing in cellular and IoT modules.
- Battery-Powered Wearables: The compact 0603 package combined with low equivalent series resistance (ESR) minimizes board space while delivering efficient energy storage.
Key Features & Advantages
- High Capacitance in 0603: 4.7µF enables bulk decoupling without oversized packages, freeing PCB real estate for additional functionality.
- X6S Temperature Stability: Capacitance variation limited to ±22% over -55°C to +105°C, ensuring consistent performance under thermal stress.
- Murata Process Control: Tight ±10% tolerance reduces design margin waste and simplifies BOM matching for volume production.
Frequently Asked Questions
- Q: What makes GRM185C81A475KE11D different from a standard X5R capacitor?
A: The X6S dielectric provides a wider operating temperature range (-55°C to +105°C) versus X5R (-55°C to +85°C), with only ±22% capacitance change, making it more robust for automotive and industrial ambient environments. - Q: Is GRM185C81A475KE11D RoHS compliant?
A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free. - Q: What is the MOQ? Can we get small batches?
A: We support small batch orders and full BOM kitting with fast prototyping supply, including flexible quantities for engineering validation.
