What is GCM21B5C1H183FA16L MLCC?
The GCM21B5C1H183FA16L is a high-stability SMD capacitor manufactured by Murata. Key specs include 0.018μF capacitance, 50V DC rating, C0G/NPO dielectric, and ±1% tolerance. RoHS compliant, it is designed for precision circuits requiring minimal capacitance drift over temperature and voltage.
✔ RoHS Compliant / ✔ 0805 Package / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Timing & Oscillator Circuits: The C0G/NP0 dielectric combined with ±1% tolerance ensures resonant frequency stability essential for crystal load caps and PLL filters.
- High-Precision ADC Reference Decoupling: 0.018μF at 50V with ultra-low capacitance change vs. DC bias maintains reference voltage integrity in 16‑bit+ acquisition systems.
- Automotive Sensor Modules: Murata’s GCM series qualification, 50V rating, and 0805 footprint suit vibration‑resistant layouts in engine control or ADAS sensor power filtering.
Key Features & Advantages
- Strict ±1% Tolerance: Enables predictable RC time constants and filter corner frequencies without post‑calibration trimming.
- C0G/NP0 Dielectric: Exhibits near‑zero capacitance change over –55°C to +125°C, vital for temperature‑sensitive designs.
- 50V Rated Voltage: Provides ample headroom for 12V, 24V, and 48V rail decoupling, reducing derating concerns in industrial power stages.
Frequently Asked Questions
