✔ RoHS Compliant / ✔ 0805 Package / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Power Decoupling in Portable Devices: With 4.7µF at 50V, this capacitor provides low-impedance decoupling for power rails in battery-powered equipment, handling ripple effectively.
- DC-DC Converter Output Filtering: The X6S dielectric offers minimal capacitance shift under DC bias, ensuring stable filtering in 50V-rated converter stages.
- Automotive Infotainment Circuits: The ±10% tolerance and 0805 footprint suit dense PCB layouts where consistent capacitance is required across temperature extremes.
Key Features & Advantages
- X6S Dielectric Stability: Maintains 80% of nominal capacitance from -55°C to +105°C, outperforming X5R in high-temperature environments.
- 50V Voltage Rating: Provides ample headroom for 24V and 48V bus applications, reducing derating concerns.
- 0805 Compact Footprint: Balances capacitance density with hand-solderability, ideal for mixed-technology assemblies.
Frequently Asked Questions
- Q: What makes GRM21BC81H475KE11L different from a standard X5R capacitor?
