KEMET Corporation has announced that its request to have Tantalum Polymer capacitors excluded from the Section 301 Chinese tariffs has been approved by the U.S. Trade Representative
Devices in the new METCOM series are ideal for developing more efficient DC to DC switching power supplies as well as other power-related applications including EMI filtering.
Polymer tantalum capacitor technology was developed in response to demands from the market to lower the ESR of tantalum capacitors while preserving their small case size and high reliability. The technology is promising in several aspects. The higher quality interface between the dielectric and the polymer cathode increases the breakdown voltage of the device, as well as reducing its DC leakage current, even at extreme radiation exposure conditions.
