What is GRM32A7U2J222JW31D MLCC?

The GRM32A7U2J222JW31D is an SMD capacitor manufactured by Murata. Key specs include 2200PF capacitance, 630V voltage rating, U2J dielectric, and 1210±5% package/tolerance. RoHS compliant, it is designed for high-voltage, stable filtering in demanding circuits.

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

Typical Applications & Why This Part Fits

• Power Supply Output Filtering: The 630V rating and 2200PF value make it ideal for smoothing ripple in high-voltage DC-DC converters, where U2J dielectric ensures minimal capacitance change over temperature.
• Snubber Circuits in Switching Converters: Its low ESR and stable U2J characteristic help damp voltage spikes in flyback or forward converters rated at 630V.
• Timing and Coupling in Industrial Controls: The tight ±5% tolerance and 1210 size allow precise timing constants and reliable AC coupling in 630V control interfaces.

Key Features & Advantages

• 630V High Voltage Rating: Handles transient surges in power rails without derating, reducing board space compared to lower-voltage parts.
• U2J Dielectric Stability: Near-zero capacitance drift across temperature (-55°C to +125°C), critical for precision circuits.
• 1210 Small-Footprint Package: Balances high voltage capability with compact SMD assembly, enabling dense PCB layouts.

Frequently Asked Questions

1. Q: What makes GRM32A7U2J222JW31D different from a standard MLCC?
   A: Its combination of 630V rating and U2J dielectric offers superior high-voltage stability and low drift, unlike X7R parts that lose capacitance under bias.
2. Q: Is GRM32A7U2J222JW31D 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, including fast prototyping supply – ideal for pre-production runs.
