MLCC GQM1555C2D1R2BB01D

What is GQM1555C2D1R2BB01D MLCC?

The GQM1555C2D1R2BB01D is a high-voltage, ultra-low capacitance SMD capacitor manufactured by Murata. Key specs include 1.2pF capacitance, 200V rating, NP0 dielectric, 0402 package, and ±0.1pF tight tolerance. RoHS compliant, it is designed for precision RF and high-voltage coupling where stability and small footprint are critical.

✔ RoHS Compliant  /  ✔ 0402  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• RF Tuning & Impedance Matching: The 1.2pF ±0.1pF ultra-low capacitance and NP0 temperature stability make it ideal for precise resonant circuits in 5G modules and VCOs.
• High-Voltage DC-DC Coupling: With a 200V rating in a tiny 0402 body, it provides reliable blocking and decoupling in PoE, industrial power supplies, and LED drivers.
• Timing & Filter Networks: The NP0 dielectric ensures negligible capacitance shift over temperature and voltage, crucial for accurate time constants in sensor interfaces.

Key Features & Advantages

• Tight ±0.1pF Tolerance: Guarantees repeatable performance in high-frequency circuits without need for manual tuning.
• 200V Rating in 0402: Delivers three times the voltage rating of typical 0402 MLCCs, enabling compact high-voltage designs.
• NP0 (C0G) Stability: Capacitance change < ±30ppm/°C, ideal for temperature-sensitive applications in automotive and telecom.

Frequently Asked Questions

1. Q: What makes GQM1555C2D1R2BB01D different from a standard 0402 1.2pF MLCC?
   A: This Murata part combines an ultra-tight ±0.1pF tolerance with a 200V rating—most standard 0402 caps are rated only 25–50V and have looser tolerance (e.g., ±0.25pF).
2. Q: Is GQM1555C2D1R2BB01D 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. Contact us for flexible quantities.
