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

Typical Applications & Why This Part Fits

• RF Decoupling / Filtering: The 82pF value combined with C0G (Class I) dielectric ensures low loss and stable performance up to 630V, ideal for suppressing noise in high-frequency power rails.
• High Voltage Snubber Networks: With ±5% tolerance and 630V rating, this MLCC reliably absorbs voltage spikes in switching converters and motor drives without drift.
• Timing and Oscillator Circuits: The C0G/NP0 material provides near-zero capacitance variation over temperature (−55°C to +125°C), making it suitable for precise timing references in industrial electronics.

Key Features & Advantages

• 630V High Voltage Rating: Enables safe operation in power management circuits where standard 50V or 100V capacitors would de-rate excessively.
• C0G/NP0 Dielectric: Offers the highest stability among MLCC dielectrics with ±30ppm/°C, negligible aging, and no voltage coefficient.
• Compact 1206 Package: Allows dense PCB layouts while withstanding high voltage stress, saving board space compared to larger leaded alternatives.

Frequently Asked Questions

1. Q: What makes GRM31A5C2J820JW01D different from a standard MLCC?
   A: Unlike general-purpose X7R or X5R parts, this Murata capacitor uses C0G/NP0 dielectric rated at 630V, ensuring stable capacitance under high voltage and extreme temperatures—critical for timing and high-reliability designs.
2. Q: Is GRM31A5C2J820JW01D 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 for this 1206 C0G capacitor.
