SMD Capacitors MLCC CGA4J4C0G2W392J125AA: 3900 pF 450V C0G ±5% for Power supply decoupling
The MLCC CGA4J4C0G2W392J125AA is a professional-grade SMD Capacitors engineered by TDK Corporation. This MLCC capacitor has a capacitance of 3900 pF, rated voltage of 450V, dielectric C0G (NP0), and tolerance of ±5%. This component is fully RoHS compliant and optimized for global supply chains.
Why Choose This Part? Unlike X7R capacitors with typical ±15% change over temperature, this C0G capacitor offers virtually no capacitance change (±30ppm/°C), ensuring stability over temperature. 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 TDK Corporation Quality / ✔ Shipping from Shenzhen / ✔ Worldwide Delivery
Typical Applications & Hardware Integration
- Power supply decoupling: The 450V rating suits high-voltage rails, and C0G ensures minimal capacitance change under DC bias..
- Timing/oscillation: The C0G dielectric offers extremely low temperature coefficient (±30ppm/°C), ideal for precise timing circuits..
- Sensor interface: The ±5% tolerance and stable capacitance over voltage make it reliable for sensor coupling..
Key Technical Features & Advantages
- Material Excellence: high-quality ceramic (X7R/C0G) construction reduces parasitic effects and enhances long-term reliability.
- Stable Capacitance: 3900pF capacitance with ±5% tolerance ensures consistent filtering and decoupling.
- Power Efficiency: Low power dissipation (1/16W typical) makes it ideal for battery‑powered and energy‑sensitive applications.
