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

Typical Applications & Why This Part Fits

• Power supply snubbers: The 630 V rating and C0G stability make this 820 pF capacitor ideal for damping high-voltage transients in switch-mode power supplies.
• RF decoupling in base stations: C0G/NP0 dielectric ensures minimal capacitance variation with temperature and voltage, crucial for maintaining consistent RF performance at 820 pF.
• Industrial sensor interfaces: The 1206 package provides robust solder joint reliability, while the tight ±5% tolerance guarantees precise timing in analog sensor conditioning.

Key Features & Advantages

• High voltage + C0G stability: 630 V rating combined with Class 1 dielectric ensures low drift and high insulation resistance over a wide temperature range.
• Compact 1206 form factor: Enables dense PCB layout without sacrificing voltage handling or capacitance value.
• Murata quality assurance: Stringent process control guarantees low defect rates and long operational life in harsh environments.

Frequently Asked Questions

1. Q: What makes GRM31B5C2J821JW01L different from a standard X7R 820 pF capacitor?
   A: This part uses C0G/NP0 dielectric, offering essentially zero capacitance change under DC bias and temperature, unlike X7R which can drop by 30% or more. The 630 V rating also far exceeds typical X7R limits.
2. Q: Is GRM31B5C2J821JW01L 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 and flexible quantities for engineering runs.
