✔ RoHS Compliant / ✔ 0805 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- DC-DC Converter Output Filtering: The 250V rating in a small 0805 footprint enables high-voltage smoothing without sacrificing board space, directly supporting 48V or 72V bus rails.
- Automotive ADAS Power Supplies: X7R stability across -55°C to +125°C ensures consistent 0.022µF capacitance for sensor modules, with ±10% tolerance meeting strict AEC-like requirements.
- Industrial I/O Protection: The 250V withstand and low ESR provide reliable noise suppression at control interfaces, handling transient surges in 24V industrial environments.
Key Features & Advantages
- High Voltage in Miniature Case: Achieves 250V DC rating in an 0805 package, significantly reducing board area compared to larger 1206 or 1812 alternatives.
- Wide Temperature Stability: X7R dielectric delivers capacitance change of only ±15% over -55°C to +125°C, ensuring predictable performance in harsh thermal conditions.
- Low ESR & ESL: Murata’s multilayer construction minimizes energy losses, making the GRM21BR72E223KW03L ideal for high-frequency bypass in power converters.
Frequently Asked Questions
- Q: What makes GRM21BR72E223KW03L different from a standard 0805 MLCC?
A: Unlike typical 50V or 100V parts, this capacitor offers a 250V rating in the same 0805 footprint, allowing high-voltage designs to stay compact without switching to larger case sizes. - Q: Is GRM21BR72E223KW03L 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 at SZYY, including fast prototyping supply – ideal for design validation and low-volume production.
