MLCC GCQ1555C1H270JB01D

What is GCQ1555C1H270JB01D MLCC?

The GCQ1555C1H270JB01D is a high-stability SMD multilayer ceramic capacitor manufactured by Murata. Key specs include 27 pF capacitance, 50 V DC rating, C0G/NP0 dielectric, and ±5% tolerance. RoHS compliant, it is designed for precision timing, filtering, and resonant circuit applications where capacitance drift must be minimized.

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

Typical Applications & Why This Part Fits

• RF Oscillator & PLL Circuits: The tight ±5% tolerance and ultra-stable C0G/NP0 characteristic ensure the 27 pF value remains nearly constant over temperature, critical for maintaining lock accuracy.
• High-Precision Sensor Interface: Low leakage and negligible voltage coefficient make this 50 V capacitor ideal for charge-amp or sample-and-hold stages that demand repeatable baseline performance.
• Decoupling in Power Modules: Its 0402 footprint saves board space while the 50 V rating provides ample headroom for 3.3 V or 5 V rails, reducing the risk of microphonic noise.

Key Features & Advantages

• C0G/NP0 Dielectric: Offers virtually zero capacitance change with temperature, delivering predictable behavior from -55 °C to +125 °C without derating.
• ±5% Tight Tolerance: Enables consistent filtering and timing in production, reducing the need for trimmer components or post-assembly calibration.
• 50 V DC Rating: Provides robust voltage margin for mixed-signal designs, improving long-term reliability even under supply ripple.

Frequently Asked Questions

1. Q: What makes GCQ1555C1H270JB01D different from a standard X7R capacitor?
   A: Unlike X7R, this Murata C0G/NP0 part exhibits essentially no capacitance change with temperature or applied DC voltage, making it the preferred choice for frequency-determining and precision analog circuits.
2. Q: Is GCQ1555C1H270JB01D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free, suitable for global manufacturing requirements.
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 for your 0402 capacitor needs.
