What is GQM1555C2D4R7BB01D MLCC?
The GQM1555C2D4R7BB01D is a high-precision SMD capacitor manufactured by Murata. Key specs include 4.7PF capacitance, 200V rated voltage, NP0 dielectric, and ±0.1pF tolerance. RoHS compliant, it is designed for RF tuning and high-voltage filtering in compact circuits.
✔ RoHS Compliant / ✔ 0402 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Matching Networks: The ±0.1pF tight tolerance and NP0 stability ensure consistent impedance matching in 2.4GHz ISM band transceivers.
- High-Voltage DC-DC Modules: The 200V rating allows direct decoupling on 48V bus converters where voltage spikes exceed 150V.
- Sensor Interface Circuits: The 4.7PF value in a 0402 package suits capacitive sensing front-ends where board space is under 5mm².
Key Features & Advantages
- ±0.1pF Precision Tolerance: Eliminates post-assembly tuning in LC oscillator and filter designs, reducing test time and cost.
- 200V DC Rated Voltage: Provides a 4× safety margin over typical 48V telecom rails, enhancing reliability against transient surges.
- NP0/C0G Temperature Coefficient: Zero capacitance drift from -55°C to +125°C, critical for precision timing and reference circuits.
Frequently Asked Questions
- Q: What makes GQM1555C2D4R7BB01D different from a standard MLCC?
A: This part uses Murata’s GQM series with a Class I NP0 dielectric and ±0.1pF tolerance, delivering ultra-stable performance over temperature and voltage, unlike generic X7R parts that vary by ±15%. - Q: Is GQM1555C2D4R7BB01D RoHS compliant?
A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free. - 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 flexible quantity splits for early-stage validation.
