C1206

SMD MLCC Capacitors | C1206 Series

Product Introduction

C1206 Series (1206 imperial / 3216 metric) is YQM ELECTRONICS' high-voltage SMD MLCC lineup, built on the robust 3.2×1.6 mm footprint. With rated voltages reaching up to 2000 V DC and capacitance extending to 100 μF, this series is engineered specifically for power supply filtering, high-voltage DC-DC converters, industrial power electronics, and any application where reliable high-voltage capacitor performance is critical.

The larger 1206 form factor provides significantly better DC bias characteristics compared to smaller MLCC sizes — maintaining a higher percentage of rated capacitance under actual operating voltage, which is crucial for stable power supply performance. Available in COG (NP0), X7R, and X5R dielectrics with tolerances from ±0.1 pF to ±20%. RoHS/REACH compliant, 260 °C lead-free reflow compatible, AEC-Q200 options available.

Core Advantages

• High-Voltage Powerhouse: Rated up to 2000 V DC — purpose-built for power supply filtering, DC-link circuits, snubber networks, and high-voltage isolation where smaller MLCC sizes cannot meet voltage requirements.
• Exceptional Capacitance Density: Up to 100 μF in a 3.2×1.6 mm SMD package — combining high capacitance with high voltage in compact surface-mount form for power-dense designs.
• Superior DC Bias Stability: Larger 1206 dielectric volume provides minimal capacitance drop under DC bias — essential for stable power rail decoupling at elevated operating voltages.
• Broad Dielectric & Voltage Matrix: COG for precision high-voltage circuits, X7R for industrial power filtering (-55~+125 °C), X5R for cost-sensitive bulk decoupling. Voltage from 6.3 V to 2000 V — one footprint for virtually all mid-to-high power design needs.

FAQ

Q: Can C1206 really handle 2000 V?

A: Yes. C1206 Series offers rated voltages up to 2000 V DC in X7R dielectric with appropriate capacitance derating. These are specifically designed for high-voltage applications. Always follow recommended derating guidelines — typically operate at ≤50% of rated voltage for maximum reliability and lifetime.

Q: How does C1206 compare to using multiple smaller MLCCs in parallel?

A: A single 1206 MLCC can replace multiple smaller capacitors, simplifying PCB layout, reducing component count, and improving reliability. The larger dielectric volume provides superior DC bias performance — a single 100 μF/50 V 1206 typically retains more capacitance at 40 V bias than several 0603 or 0805 capacitors in parallel.

Q: Is C1206 a direct replacement for Murata GRM31 or TDK C3216?

A: Yes. C1206 shares identical 3.2×1.6 mm package and pad footprint with Murata GRM31, TDK C3216, Samsung CL31, and Yageo CC1206. Matching capacitance (0.5 pF–100 μF), voltage (6.3–2000 V), and dielectric (COG/X7R/X5R) ranges — direct drop-in replacement.
