Ceramic capacitor MLCC

SMDmultilayerresistance

Resin layers in the new products cover only a board mounting side Achieve both high reliability and low resistance by the original TDK design and structure Large capacitance with new lineup featuring up to 22 μF in 3216 size and 47 μF in 3225 size Upgrades for automotive grade (compliant with AEC-Q200) and commercial grade TDK Corporation (TSE:6762) has expanded its CN series of multilayer ceramic capacitors (MLCCs) with a unique design and structure. Unlike conventional soft termination MLCCs with the entire terminal electrodes covered with resin layers, the new design features resin layers covering only a board mounting side, allowing electric current to pass outside the layers, reducing electrical resistance. The soft termination product with this structure is the first in the industry.* Adding CNA series (automotive grade) and CNC series (commercial grade) products addresses market needs for large-value capacitances. The new MLCCs feature up to 22 μF in 3216 size (3.2 × 1.6 × 1.6 mm - L x W x T) and 47 μF in 3225 size (3.2 × 2.5 × 2.5 mm - L x W x T) with low-resistance soft termination, translating to higher capacitances than conventional products and thereby helping reduce the number of parts and size. MLCCs with soft termination prevent short circuits in power and battery lines. However, since soft termination has a slightly higher terminal electrode resistance, it is necessary to keep the resistance low to reduce loss. The automotive grade CNA series are AEC-Q200 compliant. Mass production will commence in September 2023. These products are an addition to the CN series originally released in September of 2021 due to the continuing need for higher capacitance.
