What is GJM1555C1H3R1WB01D MLCC?
The GJM1555C1H3R1WB01D is a high-precision SMD ceramic capacitor manufactured by Murata. Key specs include 3.1pF capacitance, 50V voltage rating, C0G/NP0 dielectric, and an ultra-tight ±0.05pF tolerance in a 0402 package. RoHS compliant, it is designed for RF and timing circuits where capacitance accuracy and temperature stability are critical.
✔ RoHS Compliant / ✔ 0402 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Impedance Matching: The ±0.05pF tolerance ensures minimal deviation in resonant frequency, critical for antenna tuners and filter networks operating at 50V.
- High-Speed Timing Circuits: C0G/NP0 dielectric provides near-zero capacitance drift over temperature (−55°C to +125°C), preserving timing accuracy in oscillator and PLL designs.
- Sensor Interface Filtering: 3.1pF with 50V rating allows clean decoupling in high-impedance sensor nodes without loading the signal source.
Key Features & Advantages
- Extreme Tolerance Precision: ±0.05pF tolerance enables repeatable circuit performance without manual tuning, reducing production calibration cost.
- C0G/NP0 Stability: Class 1 dielectric ensures capacitance changes less than ±30ppm/°C, ideal for temperature-sensitive RF and precision analog paths.
- High Voltage in Compact Footprint: 50V rating in 0402 allows direct decoupling on 48V power rails or battery lines while saving board area.
Frequently Asked Questions
- Q: What makes GJM1555C1H3R1WB01D different from a standard 0402 MLCC?
A: It offers a ±0.05pF tolerance and C0G/NP0 dielectric—standard MLCCs typically have looser tolerance (e.g., ±0.25pF or ±5%) and may use Class 2 dielectrics like X7R that drift with voltage and temperature. - Q: Is GJM1555C1H3R1WB01D 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 fast BOM kitting support at SZYY, including prototyping quantities for this precision MLCC.
