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

Typical Applications & Why This Part Fits

• DC-DC Converter Output Filtering: The 3.3µF value and X6S temperature stability (from -55°C to +105°C) ensure smooth voltage ripple suppression in automotive and industrial power modules.
• Portable Device Decoupling: The compact 0805 package and 25V rating suit battery-powered electronics where board space is constrained, providing effective noise bypass for IC rails.
• Sensor Signal Conditioning: ±10% tolerance offers reliable capacitance consistency in timing or coupling applications, while X6S dielectric minimizes capacitance change under bias.

Key Features & Advantages

• Wide Operating Temperature Range: X6S dielectric supports -55°C to +105°C, making it suitable for harsh environments without significant capacitance drift.
• High Reliability Construction: Murata’s advanced stacking and termination technology ensures low equivalent series resistance (ESR) and long-term stability under DC bias.
• Optimized for High-Density Assembly: The 0805 footprint balances power handling and miniaturization, simplifying layout in multi-layer PCBs.

Frequently Asked Questions

1. Q: What makes GRT21BC81E335KE13L different from a standard X7R capacitor?
