SMD Capacitor MLCC CL21Y105MR5NJNC: 1µF 4V for Power Supply Decoupling
The MLCC CL21Y105MR5NJNC is a professional-grade SMD Capacitors engineered by Samsung Electro-Mechanics. This MLCC has a capacitance of 1µF, a rated voltage of 4V, X7S dielectric, and ±20% tolerance. This component is fully RoHS compliant and optimized for global supply chains.
Why Choose This Part? Unlike typical X5R capacitors with ±55% capacitance change over temperature, the X7S dielectric provides a tighter variation of ±22% over -55°C to +125°C, ensuring stable performance in extreme conditions. As a trusted electronic components supplier, we ensure every part is a genuine part with full traceability. Our BOM kitting service helps you consolidate your entire BOM from a single source, saving time and cost.
✔ RoHS Compliant / ✔ Package: SMD / ✔ Authentic Samsung Electro-Mechanics Quality / ✔ Shipping from Shenzhen / ✔ Worldwide Delivery
Typical Applications & Hardware Integration
- Harsh environment bypass: The X7S dielectric operates reliably from -55°C to +125°C, ideal for extreme conditions..
- Signal conditioning: The 1µF capacitance provides effective filtering in audio frequency ranges..
- Power supply decoupling: The 4V rating matches low-voltage supply rails, and the 1µF value suppresses high-frequency noise..
Key Technical Features & Advantages
- Wide Temperature Stability: Designed to operate reliably from -55°C to +125°C, suitable for harsh environments.
- Power Efficiency: Low power dissipation (1/16W typical) makes it ideal for battery‑powered and energy‑sensitive applications.
- Stable Capacitance: 1µF capacitance with ±20% tolerance ensures consistent filtering and decoupling.
