What is GRM21B5C1H183JA01K MLCC?
The GRM21B5C1H183JA01K is an SMD capacitor manufactured by Murata. Key specs include 0.018μF capacitance, 50V voltage rating, C0G/NP0 dielectric, and ±5% tolerance. RoHS compliant, it is designed for high-stability and low-loss circuit applications.
✔ RoHS Compliant / ✔ 0805 Package / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- High-Frequency Decoupling: The C0G/NP0 dielectric offers minimal ESR and stable capacitance up to 50V, making it ideal for RF module decoupling where low noise is critical.
- Timing & Oscillator Circuits: With ±5% tolerance and no aging effect, this 0.018μF capacitor ensures precise time constants in crystal oscillator and PLL circuits.
- Precision Analog Filtering: The tight capacitance stability over temperature (±30ppm/°C) supports accurate filtering in sensor signal chains and audio applications.
Key Features & Advantages
- C0G/NP0 Dielectric: Provides virtually flat capacitance vs. temperature and voltage, eliminating the need for derating in bias-sensitive designs.
- ±5% Tight Tolerance: Enables consistent performance in frequency-determining networks without manual tuning.
- 0805 Compact Footprint: Balances small size with ease of hand-assembly and automated pick-and-place for space-constrained PCBs.
Frequently Asked Questions
- Q: What makes GRM21B5C1H183JA01K different from a standard MLCC?
A: Unlike X7R or X5R types, this capacitor uses a C0G/NP0 formulation that offers negligible capacitance change with temperature and applied DC bias, plus no piezoelectric effects. - Q: Is GRM21B5C1H183JA01K RoHS compliant?
A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free. - Q: What is the MOQ? Can we get small batches?
A: Minimum order quantity is flexible, and small batch orders are welcome for prototyping or low-volume production.
