MLCC GCM1885C1H121JA16D

What is GCM1885C1H121JA16D MLCC?

The GCM1885C1H121JA16D is a SMD Capacitor manufactured by Murata. Key specs include 120pF capacitance, 50V voltage rating, C0G/NP0 dielectric, and ±5% tolerance. RoHS compliant, it is designed for circuits demanding precise capacitance and low drift over temperature and voltage.

✔ RoHS Compliant  /  ✔ 0603 Package  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• High-Frequency Filtering: The 120pF value and tight ±5% tolerance enable accurate cutoff frequencies in LC filters, while C0G dielectric ensures minimal capacitance shift with temperature.
• Timing Circuits: Excellent aging performance of C0G (Class I) dielectric keeps oscillation timing stable over years, making it ideal for oscillator feedback paths.
• Coupling/Decoupling in RF Modules: Low equivalent series resistance (ESR) from the 0603 form factor and NP0 formulation reduces signal loss at frequencies up to GHz range.

Key Features & Advantages

• C0G/NP0 Dielectric: Provides negligible capacitance variation (±30ppm/°C) across the full −55°C to +125°C operating range.
• ±5% Tight Tolerance: Ensures repeatable circuit behavior without the need for trimming, reducing component count in precision designs.
• 50V Rated Voltage: Offers a comfortable derating margin for common 3.3V, 5V, and 12V supplies, enhancing long-term reliability.

Frequently Asked Questions

1. Q: What makes GCM1885C1H121JA16D different from a standard MLCC?
   A: Unlike X7R or X5R dielectrics, this part uses C0G (NP0) which exhibits virtually no capacitance change under DC bias or temperature, making it superior for timing and RF circuits.
2. Q: Is GCM1885C1H121JA16D 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 and flexible quantity splits.
