MLCC GQM1555C2D3R3BB01D

What is GQM1555C2D3R3BB01D MLCC?

The GQM1555C2D3R3BB01D is a Class 1 SMD capacitor manufactured by Murata (Murata). Key specs include a capacitance of 3.3 pF, rated voltage of 200 V, NP0 (C0G) dielectric, 0402 package size, and tolerance of ±0.1 pF. RoHS compliant, it is designed for ultra‑stable, high‑frequency filtering and timing circuits where capacitance drift must be minimized.

Typical Applications & Why This Part Fits

• RF Transceiver Matching Networks: The 3.3 pF value with ±0.1 pF tolerance and NP0 dielectric ensure negligible capacitance change over temperature and voltage, critical for impedance matching in 2.4 GHz ISM band modules.
• High‑Voltage Snubbers in DC‑DC Converters: A 200 V rating in an 0402 footprint allows placement in tight power stages where voltage spikes exceed 100 V, while the low‑loss NP0 material prevents self‑heating.
• Precision Timing Oscillators: The tight ±0.1 pF tolerance and ultra‑low aging of NP0 make this MLCC suitable for tank circuits in crystal‑less oscillator designs requiring stable frequency over –55°C to +125°C.

Key Features & Advantages

• NP0 (C0G) Dielectric: Provides ±30 ppm/°C temperature coefficient and virtually no DC bias dependence, ensuring consistent capacitance across operating conditions.
• 200 V Rated Voltage in 0402: Offers a high voltage margin for compact power electronics without sacrificing board space, enabling slim power supplies and LED drivers.
• ±0.1 pF Tight Tolerance: Guarantees repeatable performance in resonant circuits and filters, reducing tuning effort in production and prototypes.

Frequently Asked Questions

1. Q: What makes GQM1555C2D3R3BB01D different from a standard 0402 X7R capacitor?
   A: Unlike X7R, the NP0 dielectric exhibits zero capacitance change with voltage and temperature. The 3.3 pF value stays within ±0.1 pF over full temperature range, while a typical X7R part of the same value can drop 20–50% under 200 V bias.
2. Q: Is GQM1555C2D3R3BB01D 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 for low-volume pre‑production runs.
