What is GQM2195C2E4R7BB12D MLCC?
The GQM2195C2E4R7BB12D is a precision SMD capacitor manufactured by Murata (村田). Key specs include 4.7pF ±0.1pF capacitance, 250V voltage rating, and C0G/NP0 dielectric in an 0805 package. RoHS compliant, it is designed for high-frequency and high-voltage applications requiring exceptional temperature stability.
✔ RoHS Compliant / ✔ 0805 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Matching Networks: The ±0.1pF tight tolerance and C0G/NP0 dielectric ensure minimal capacitance drift across temperature and frequency, critical for precise impedance matching in transceivers.
- High-Voltage DC-DC Converters: Rated at 250V, this MLCC handles snubber and filter circuits where voltage spikes exceed 100V, while the compact 0805 footprint saves board space.
- VCO & PLL Loop Filters: Low dielectric absorption and high Q factor of C0G/NP0 make the 4.7pF value ideal for stable reference frequency generation without phase noise penalty.
Key Features & Advantages
- Ultra-Tight Tolerance (±0.1pF): Eliminates the need for post‑assembly tuning in RF circuits, reducing manufacturing cost and complexity.
- High Voltage + Small Size: 250V in 0805 enables dense power stage layouts where traditional larger capacitors cannot fit.
- C0G/NP0 Temperature Stability: Capacitance changes less than ±30ppm/°C, ensuring consistent performance from -55°C to +125°C.
Frequently Asked Questions
- Q: What makes GQM2195C2E4R7BB12D different from a standard 4.7pF 0805 capacitor?
A: The 250V rating and ±0.1pF tolerance are exceptional – most standard parts are rated 50V and ±0.25pF. This part is engineered for high-reliability RF/power designs. - Q: Is GQM2195C2E4R7BB12D 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.
