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

Typical Applications & Why This Part Fits

• AC-DC Power Supplies: The 2 kV rated voltage and U2J (low TCC) dielectric make it ideal for snubber and input filter circuits where high voltage spikes occur.
• RF & Impedance Matching Networks: The 100 pF value and ±5% tight tolerance provide precise reactance for matching stages in transmitters and industrial RF generators.
• High-Voltage DC-DC Converters: Its 1210 footprint allows safe creepage distance while maintaining compactness, suitable for bias supplies and voltage multiplier stages.

Key Features & Advantages

• 2 kV Voltage Rating: Delivers reliable operation in circuits with sustained high DC bias or transient overvoltage conditions.
• U2J Dielectric: Features low capacitance change over temperature (±60 ppm/°C typical), ensuring stable filtering in thermally stressed environments.
• 1210 / SMD Package: Compatible with standard reflow soldering and offers good mechanical strength for repeated thermal cycling.

Frequently Asked Questions

1. Q: What makes GRM32A7U3D101JW31D different from a standard 100 pF capacitor?
   A: Its 2 kV rating and U2J dielectric reduce voltage coefficient and leakage, making it suitable where regular X7R or C0G parts would fail under high DC bias.
2. Q: Is GRM32A7U3D101JW31D 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 low quantity options for this capacitor.
