Typical Applications & Why This Part Fits

• RF & Wireless Modules: The U2J dielectric offers ultra-stable capacitance over voltage and temperature, ensuring consistent resonant frequency in 4700pF tank circuits.
• Precision Timing Circuits: ±5% tolerance guarantees tight matching in RC time-constant networks, critical for 50V-rated charge pump stages.
• Sensor Interface Filtering: 4700pF at 50V provides effective EMC suppression in industrial sensor lines without introducing nonlinear ceramic distortion.

Key Features & Advantages

• U2J Dielectric Stability: Near-zero voltage coefficient delivers predictable 4700pF capacitance across the full 50V DC bias range.
• Murata Manufacturing Consistency: Tight process control ensures ±5% tolerance repeatability from reel to reel, reducing design margin requirements.
• Compact 0603 Footprint: Saves board space while handling 50V rated voltage — ideal for high-density consumer and industrial assemblies.

Frequently Asked Questions

1. Q: What makes GRM1857U1H472JA44D different from a standard X7R capacitor?
   A: Unlike X7R, the U2J dielectric exhibits minimal capacitance change under DC bias — less than ±0.1% typical at 50V — ensuring true 4700pF performance in voltage-sensitive paths.
2. Q: Is GRM1857U1H472JA44D 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 with flexible reel breakout quantities.
