With a rated voltage of 100V-630V for mid-voltage applications, TDK’s multilayer ceramic chip capacitors use ceramic dielectric thin-layer and multi-layering technologies to improve capacitance to the industry’s highest levels in the mid-voltage range.

As the fundamental driving performance of electronic equipment and devices improves, there is a substantial increase in the use of electronic passive components. In addition, next-generation eco-friendly electronics that can contribute to reducing environmental impact through better efficiency and lower emissions have attracted considerable attention. Amidst these developments, the number of electronic components installed in limited space is increasing, and market demand is rising for components that can contribute to the miniaturization of capacitance. TDK is responding to these market needs by using its strengths in materials and multi-layering technologies to reduce the gaps between ceramic dielectric layers by approximately 40% compared to earlier products.

These products feature X6S, C0G, X7R, X7S, and X7T temperature characteristics making them ideal for applications requiring higher operating temperatures and voltage requirements. The X6S Dielectric has an operating temperature range of -55°C to 105°C, while the C0G, X7R, X7S, and X7T exhibit an operating temperature of -55°C to 125°C respectively.
