September 24, 2025 /SemiMedia/ — TDK Corporation said it has expanded its CN series of soft-termination multilayer ceramic capacitors (MLCCs), launching what it calls the industry’s first product to combine 22 nF capacitance in the 3225 size with C0G characteristics at 1000 volts. Mass production began this month.

The new capacitors address rising demand for high-voltage, large-capacitance components used in applications such as LLC resonant converters and wireless charging. Traditional resin electrode designs improve resistance to mechanical stress but have been limited by higher resistance values.

TDK said its optimized resin electrode structure overcomes this issue, delivering low resistance comparable to standard terminals while retaining the stability and low-loss characteristics of C0G products. The result is higher reliability and efficiency for resonator and snubber circuits.
