✔ RoHS Compliant / ✔ 0805 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Precision Timing Circuits: The U2J dielectric offers superb temperature stability (±10% over -55°C to +125°C), ensuring consistent performance in oscillators and PLL loops.
- RF Decoupling & Filtering: Low ESR and high Q at MHz frequencies make this capacitor ideal for noise suppression in communication modules and wireless transceivers.
- Industrial Control Systems: With 50V rating and ±5% tolerance, it reliably handles voltage transients in PLCs, motor drives, and power monitoring units.
Key Features & Advantages
- U2J Dielectric: Combines the linearity of Class 1 ceramics with higher capacitance density, delivering excellent capacitance‑voltage (C-V) characteristics.
- Low ESR & Low Loss: Minimizes power dissipation in high‑frequency circuits, improving overall system efficiency.
- 0805 Compact Footprint: Space‑saving design for dense PCB layouts while maintaining a standard, easy-to‑solder size.
Frequently Asked Questions
- Q: What makes GRM21B7U1H473JA01L different from a standard X7R MLCC?
A: Unlike X7R, the U2J dielectric provides a nearly flat capacitance change over temperature and voltage, making it ideal for frequency‑sensitive or precision analog circuits. - Q: Is GRM21B7U1H473JA01L RoHS compliant?
A: Yes, as a Murata product, it is fully RoHS compliant and lead‑free, meeting global environmental standards. - 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 for immediate design validation.
