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

Typical Applications & Why This Part Fits

• DC-DC Converter Output Filtering: The 250V voltage rating provides ample headroom for high-voltage bus rails, while the 4700pF capacitance effectively attenuates high-frequency switching noise.
• Industrial Sensor Interface Circuits: X7R dielectric ensures stable capacitance across -55°C to +125°C, critical for consistent signal conditioning in harsh environments.
• Telecom Power Distribution: The 0805 package combines a compact footprint with the 250V rating, enabling dense PCB layouts where board space is at a premium.

Key Features & Advantages

• High Voltage Rating in Small Case: Achieves 250V withstand in an 0805 body, reducing the need for larger, higher-cost capacitors in power-stage designs.
• Stable X7R Dielectric: Delivers predictable performance over a wide temperature range, minimizing capacitance drift in thermal cycling applications.
• ±10% Tolerance Control: Tight tolerance ensures consistent timing and filtering behavior across production batches, simplifying design validation.

Frequently Asked Questions

1. Q: What makes GRM21AR72E472KW01D different from a standard X7R capacitor?
   A: Its 250V voltage rating in a standard 0805 package is uncommon—most similarly sized X7R parts are limited to 50V or 100V, making this part ideal for higher-voltage rail applications.
2. Q: Is GRM21AR72E472KW01D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free.
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 and flexible quantities for engineering builds.
