MLCC GCQ1555C1H140JB01D

What is GCQ1555C1H140JB01D MLCC?

The GCQ1555C1H140JB01D is a high-frequency multilayer ceramic capacitor manufactured by Murata. Key specs include 14pF capacitance, 50V DC rating, C0G/NP0 dielectric, and ±5% tolerance. RoHS compliant, it is designed for precise timing and resonant circuit applications.

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

Typical Applications & Why This Part Fits

• RF Tuning & Filter Circuits: The tight ±5% tolerance and C0G/NP0 temperature stability (ΔC ±30ppm/°C) ensure minimal frequency drift in oscillators and LC filters.
• High-Speed Signal Coupling: 50V breakdown margin with ultra-low ESR (typ. < 50mΩ) provides clean AC coupling in Ethernet or LVDS pathways without signal degradation.
• Sensor Interface Decoupling: 14pF value matches typical parasitic capacitance of MEMS sensors; 0402 footprint saves board space close to sensor pins.

Key Features & Advantages

• C0G/NP0 Dielectric: Offers flat capacitance vs. temperature curve, essential for frequency-determining networks where capacity shift directly affects performance.
• ±5% Tight Tolerance: Reduces design guard banding, preventing yield loss in high-volume production of precision analog front-ends.
• 0402 Miniature Footprint: Permits dense PCB layouts in compact IoT modules or handheld devices while maintaining 50V voltage rating.

Frequently Asked Questions

1. Q: What makes GCQ1555C1H140JB01D different from a standard X7R 14pF capacitor?
   A: Unlike X7R (which varies up to ±15% over temperature), this C0G/NP0 part holds capacitance within ±30ppm/°C, preserving circuit timing accuracy in RF applications. Also, it shows negligible DC bias effects.
2. Q: Is GCQ1555C1H140JB01D 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, even for quantities below 100 pieces.
