✔ RoHS Compliant  /  ✔ SMD  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• High-Voltage Power Inverters: The 630V rating ensures reliable operation in 400V bus architectures, while C0G/NP0 guarantees minimal capacitance drift under high DC bias.
• Precision Timing Circuits: ±5% tolerance and ultra-low TCC (±30ppm/°C) make it ideal for oscillators and filter networks that require consistent performance across -55°C to +125°C.
• Communication Base Station Filters: 1206 footprint with 470pF value suits RF decoupling in high-frequency paths, where parasitic inductance must be kept low and Q factor high.

Key Features & Advantages

• High Voltage Rating (630V): Enables direct connection to high-voltage rails without series stacking, reducing PCB space and component count.
• Stable C0G/NP0 Dielectric: Capacitance variation less than ±0.3% from -55°C to +125°C, ideal for resonant circuits and filters requiring predictable behavior.
• Tight ±5% Tolerance: Reduces design margin overhead, simplifying matching in differential signal paths and precision analog stages.

Frequently Asked Questions

1. Q: What makes GRM31A5C2J471JW01D different from a standard X7R capacitor?
   A: Unlike X7R, the C0G/NP0 formulation provides negligible voltage coefficient and near-zero aging, ensuring the 470pF value remains constant even under 630V stress and extreme temperatures.
2. Q: Is GRM31A5C2J471JW01D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free, meeting EU directives for solderability and environmental safety.
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. Minimum order quantities are flexible for engineering samples and low-volume production.
