SMD Capacitors MLCC CGA4J4C0G2W392J125AE: 3900 pF 450V C0G ±5% for Signal Conditioning
The MLCC CGA4J4C0G2W392J125AE is a professional-grade SMD Capacitors engineered by TDK Corporation. This MLCC has a capacitance of 3900 pF, a rated voltage of 450V, a C0G/NP0 dielectric, and a tolerance of ±5%. This component is fully RoHS compliant and optimized for global supply chains.
Why Choose This Part? Unlike typical X7R MLCCs which can lose up to 70% capacitance at rated voltage, this C0G part maintains full capacitance, improving accuracy by up to 2x in precision circuits. 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: 450V rating allows use in high-voltage rails, and C0G provides stable capacitance which does not vary with bias..
- Sensor interface: ±5% tolerance and stable dielectric ensure accurate signal coupling in precision sensor circuits..
- Harsh environment bypass: C0G dielectric is stable over wide temperature range and voltage, making it suitable for bypass capacitors in harsh environments..
Key Technical Features & Advantages
- Stable Capacitance: 3900pF capacitance with ±5% tolerance ensures consistent filtering and decoupling.
- Material Excellence: high-quality ceramic (X7R/C0G) construction reduces parasitic effects and enhances long-term reliability.
- Power Efficiency: Low power dissipation (1/16W typical) makes it ideal for battery‑powered and energy‑sensitive applications.
