MLCC GJM1555C1H8R5WB01D

What is GJM1555C1H8R5WB01D MLCC?

The GJM1555C1H8R5WB01D is a high-frequency SMD capacitor manufactured by Murata. Key specs include 8.5 pF capacitance, 50 V voltage rating, C0G/NP0 dielectric, and a tight ±0.05 pF tolerance. RoHS compliant, it is designed for precision timing and RF coupling applications.

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

Typical Applications & Why This Part Fits

• RF Impedance Matching Networks: The 8.5 pF value with ±0.05 pF tolerance ensures precise reactive matching in 50 Ω RF paths, minimizing VSWR and insertion loss.
• PLL Loop Filter Compensation: The C0G/NP0 dielectric provides negligible voltage coefficient and flat temperature response, critical for stable phase-locked loop bandwidth control.
• High-Speed Signal DC Blocking: The 50 V rating combined with low ESR at GHz frequencies makes it suitable for blocking DC bias in 3.3 V/5 V logic paths without distorting fast edge rates.

Key Features & Advantages

• Ultra-Tight ±0.05 pF Tolerance: Enables repeatable filter corner frequencies without post-tuning, reducing production test time in high-volume wireless modules.
• C0G/NP0 Temperature Stability: Capacitance drift is less than ±30 ppm/°C, eliminating frequency pulling in oscillators and VCOs across -55°C to +125°C.
• 0402 Miniature Footprint: Occupies minimal PCB area while maintaining 50 V break-down margin, ideal for space-constrained IoT and wearables designs.

Frequently Asked Questions

1. Q: What makes GJM1555C1H8R5WB01D different from a standard MLCC?
   A: The ±0.05 pF absolute tolerance and C0G/NP0 ceramic provide near-ideal capacitance stability over voltage, temperature, and frequency – unlike X7R or X5R dielectrics which can vary by 30% or more.
2. Q: Is GJM1555C1H8R5WB01D 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 with quick turnaround for engineering samples.
