What is GJM1555C1H4R1WB01D MLCC?
The GJM1555C1H4R1WB01D is a precision SMD capacitor manufactured by Murata. Key specs include 4.1pF capacitance, 50V voltage rating, C0G/NP0 dielectric, and ±0.05pF tight tolerance in an 0402 package. RoHS compliant, it is designed for ultra-stable, high-frequency decoupling and filtering.
✔ RoHS Compliant / ✔ 0402 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Tuning & Impedance Matching: The ±0.05pF tolerance and C0G/NP0 temperature stability ensure consistent performance in narrow-band RF circuits, maintaining resonance accuracy across temperature.
- High-Speed Signal Filtering: The 4.1pF value combined with the 0402 footprint minimizes parasitic inductance, making it ideal for high-speed data line filters and PLL loop filters where capacitance drift is unacceptable.
- Space-Constrained Wearables: The tiny 0402 size allows integration into compact IoT modules and hearing aids, while the 50V rating provides ample safety margin for battery-powered systems.
Key Features & Advantages
- Ultra-Tight Tolerance (±0.05pF): Enables precise capacitance selection for critical RF and timing circuits without post-tuning.
- Low TCC (C0G/NP0): Capacitance variation less than ±30ppm/°C ensures reliable operation from -55°C to +125°C.
- Small 0402 Case: Saves PCB real estate while supporting high-density designs, with a low ESL profile for decoupling up to 50V.
Frequently Asked Questions
- Q: What makes GJM1555C1H4R1WB01D different from a standard MLCC?
A: The tight ±0.05pF tolerance and C0G/NP0 dielectric deliver near-zero voltage and temperature coefficient, unlike standard X7R parts which can vary by ±15% over voltage. - Q: Is GJM1555C1H4R1WB01D 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 quantities for design validation.
