Current-compensated ring core chokes

26 May 2021 Circuit & System Protection

TDK has released a new series of current-compensated EPCOS double-ring core chokes for the suppression of common-mode interference. They are available in three sizes with current handling capacities between 10 A and 17 A and with a rated voltage of 250 V a.c. (50/60 Hz). Depending on the type, the inductance value is between 1,0 mH and 6,25 mH.

The plastic material of the base plate and spacer in the middle of the ring core conforms with UL 94 V-0 and the highest CTI value of >600. In order to meet the high requirements for specific applications in domestic appliances, in accordance with IEC 60335-2-xx, the plastic meets specifications for GWIT (+775°C), GWFI (850°C) and ball pressure (+190°C), as well as CTI >250. These high requirements are increasingly found in industrial applications such as drives.

These EMC components offer extremely small dimensions in relation to their current capacity, with dimensions of between 33 x 23 x 30 mm and 39 x 23 x 37 mm. Due to the leakage inductance of around 0,4%, the RoHS-compatible ring core chokes also suppress symmetrical interference. The main areas of application are switch-mode power supplies, converters and domestic appliances.
