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

Typical Applications & Why This Part Fits

• High-Voltage Snubber Circuits: The 2kV rating and U2J’s low dissipation factor ensure reliable damping of voltage transients in power supplies.
• DC-DC Converter Output Filtering: 220pF with ±5% tolerance provides predictable, low-ripple filtering at high frequencies without resonance drift.
• Automotive On-Board Charger Coupling: U2J dielectric offers stable capacitance over temperature and voltage, critical for EV charging modules and isolation barriers.

Key Features & Advantages

• 2kV High-Voltage Rating: Enables safe operation in power-stage and snubber designs without derating concerns.
• U2J Dielectric Stability: Minimal capacitance change under DC bias and across –55°C to +125°C, ensuring consistent circuit performance.
• Compact 1210 Case Size: Balances high-voltage clearance with small footprint, ideal for space-constrained PCBs.

Frequently Asked Questions

1. Q: What makes GRM32B7U3D221JW31L different from a standard X7R MLCC?
   A: Unlike X7R, U2J dielectric delivers near-zero voltage coefficient and stable capacitance up to 2kV, making it suited for precision filtering where X7R would experience significant capacitance loss.
2. Q: Is GRM32B7U3D221JW31L 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 quantity options.
