What is GJM1555C1H4R8WB01D MLCC?

The GJM1555C1H4R8WB01D is a SMD Capacitor manufactured by Murata. Key specs include 4.8pF capacitance, 50V voltage rating, C0G/NP0 dielectric, ±0.05pF tolerance. RoHS compliant, it is designed for high-precision RF and timing circuits.

✔ RoHS Compliant  /  ✔ 0402  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• RF Impedance Matching: The ±0.05pF ultra-tight tolerance minimizes signal reflection, making it ideal for critical 50Ω matching networks in wireless modules.
• Crystal Oscillator Load Capacitors: C0G/NP0 dielectric provides near-zero capacitance drift over temperature and voltage, ensuring stable oscillation frequency.
• High-Speed Digital AC Coupling: The small 0402 package reduces parasitic inductance, while the precise capacitance value maintains consistent signal integrity in SerDes links.

Key Features & Advantages

• ±0.05pF Tolerance: Enables exact circuit tuning without trimming—critical for narrowband filters and VCO tank circuits.
• C0G/NP0 Dielectric: Offers excellent temperature stability (±30ppm/°C) and ultra-low dissipation factor (DF <0.1%).
• 50V Rating: Provides adequate headroom for battery-powered and 3.3V/5V logic designs, reducing derating concerns.

Frequently Asked Questions

1. Q: What makes GJM1555C1H4R8WB01D different from a standard 4.8pF MLCC?
   A: Standard MLCCs typically have ±0.25pF or looser tolerance; this Murata part guarantees ±0.05pF with high Q (quality factor) for RF applications.
2. Q: Is GJM1555C1H4R8WB01D 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.
