What is GRT21BC81E335KE13K MLCC?
The GRT21BC81E335KE13K is an SMD Multilayer Ceramic Capacitor manufactured by Murata. Key specs include 3.3µF capacitance, 25V rated voltage, X6S dielectric, and ±10% tolerance. RoHS compliant, it is designed for stable decoupling and filtering in space-constrained circuits.
✔ RoHS Compliant / ✔ 0805 Package / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Power Supply Decoupling: The 3.3µF capacitance with 25V rating effectively suppresses high-frequency noise in DC-DC converter outputs, while X6S ensures stable capacitance across -55°C to +105°C.
- Portable Electronics: 0805 package saves PCB space in smartphones and wearables, and the ±10% tolerance provides consistent filtering for power management ICs.
- Automotive Infotainment: X6S dielectric offers improved temperature stability over X5R, meeting the reliability demands of in-vehicle audio and display modules under 25V bus rails.
Key Features & Advantages
- Wide-Temperature X6S Dielectric: Capacitance change within ±22% from -55°C to +105°C ensures reliable performance in thermal cycling.
- Compact 0805 Footprint: Enables high-density placement without compromising capacitance density, ideal for miniaturized designs.
- 25V Voltage Rating: Sufficient headroom for 12V or 24V rails, reducing derating concerns in intermediate bus applications.
Frequently Asked Questions
- Q: What makes GRT21BC81E335KE13K different from a standard X5R capacitor?
