TDK introduces EIA 2220 size compact CeraLink capacitor

     TDK Group has expanded its mature CeraLink series capacitor product portfolio to cover small sizes. Previously, the portfolio included only out of the box large size models. In order to expand its application scope, we have introduced a small size model with classic chip design. The package size of the new series of components is as small as EIA 2220, only 5.7 x 5 x 1.4 mm. The model with order code B58043 * has a working voltage of 500V and a capacitance of 250 nF. New components currently have two packaging methods: standard and soft terminal. It is expected that more size and voltage level options will be added in the future

     The allowable operating temperature range of the new element is - 40 ° C to+150 ° C. One of its unique highlights is its ultra-low parasitic coefficient: at room temperature and 1 MHz, the equivalent series resistance (ESR) is only 40 m Ω, and the equivalent series inductance (ESL) is 3 nH; The ESR and ESL values at higher temperatures are even lower. With this feature, the new element can achieve a high current capability of up to 9 ARMS at 200 kHz and 25 ° C ambient temperature.

     Typical applications of the new series of components include absorption capacitors or output filter capacitors. The compact CeraLink SMD version can be installed closer to fast breaking power semiconductors (such as IGBT modules, SiC based or GaN based semiconductors), and its low ESL value characteristics can achieve ultra-low lead inductance.

     CeraLink series capacitors are based on lanthanum doped lead zirconate titanate (PLZT) ceramic technology. Compared with traditional ceramic capacitors, they can provide the maximum capacity under the operating voltage, and even increase with the increase of ripple voltage ratio
