MLCC GRM31A5C2J100JW01D

What is GRM31A5C2J100JW01D MLCC?

The GRM31A5C2J100JW01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata (村田). Key specs include 10pF capacitance, 630V voltage rating, C0G/NP0 dielectric, 1206 footprint, and ±5% tolerance. RoHS compliant, it is designed for high-voltage, high-stability filtering and coupling applications.

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

Typical Applications & Why This Part Fits

• Power supply snubber circuits: The 630V rating and C0G/NP0 dielectric ensure minimal capacitance change under DC bias, making it ideal for voltage spike suppression in high-voltage DC-DC converters.
• RF coupling in base stations: Low ESR and stable capacitance over temperature (C0G) maintain signal integrity at high frequencies, while the 1206 package reduces parasitic inductance.
• Industrial sensor interfaces: ±5% tolerance guarantees precise timing in RC filters, and the small 10pF value suits high-impedance input stages without loading the signal.

Key Features & Advantages

• High voltage capability: 630V rating exceeds typical 1206 MLCC limits, enabling use in power stages without derating concerns.
• Ultra-stable dielectric: C0G/NP0 provides near-zero capacitance drift with temperature (±30ppm/°C) and voltage, ensuring predictable circuit behavior.
• Compact 1206 SMD package: Balances power handling and board space, compatible with automated assembly for medium‑density designs.

Frequently Asked Questions

1. Q: What makes GRM31A5C2J100JW01D different from a standard 10pF 1206 MLCC?
   A: Its 630V voltage rating is significantly higher than typical 50V–100V parts, allowing operation in high‑voltage rails without series stacking. The C0G dielectric also offers superior stability vs X7R or X5R.
2. Q: Is GRM31A5C2J100JW01D 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 flexibility for low‑volume production.
