What is GCJ21AR72E472KXJ1D MLCC?
The GCJ21AR72E472KXJ1D is an SMD capacitor manufactured by Murata. Key specs include CAP CER 4700PF 250V X7R 0805±10%. RoHS compliant, it is designed for high-voltage decoupling and filtering in space-constrained boards.
✔ RoHS Compliant / ✔ 0805 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Industrial Power Supplies: The 250V rating and stable X7R dielectric ensure reliable filtering and snubbing in high-voltage DC-DC converters.
- Automotive ECU Modules: With 4700pF capacitance and tight ±10% tolerance, it provides consistent bypass performance in engine control units operating at elevated voltages.
- LED Lighting Drivers: The 0805 package fits compact driver layouts while handling up to 250V, making it ideal for EMI suppression in AC-DC conversion stages.
Key Features & Advantages
- High Voltage Handling: Rated at 250V, it comfortably exceeds standard 50V/100V MLCC margins, reducing failure risks in power rail decoupling.
- X7R Temperature Stability: Capacitance change within ±15% over -55°C to +125°C, ensuring consistent performance across harsh environments.
- Compact 0805 Footprint: Saves board space compared to larger high-voltage alternatives while maintaining adequate creepage distance for 250V operation.
Frequently Asked Questions
- Q: What makes GCJ21AR72E472KXJ1D different from a standard 0805 MLCC?
A: This Murata part combines a 250V rating with X7R stability in a standard 0805 size, whereas many 0805 MLCCs are limited to 50V or 100V. It supports high-voltage applications without requiring larger case sizes. - Q: Is GCJ21AR72E472KXJ1D 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. Fast BOM kitting support is available for low-volume needs.
