EPCOS manufactures a comprehensive range of current-compensated chokes. They are highly effective in suppressing common-mode interference, which occurs as an unwanted side-effect during the operation of switch-mode power supplies (SMPS) and frequency converters. EPCOS offers chokes that cover extensive requirements in terms of rated current, ambient temperature and dimensions.
Toroidal-core chokes have become standard on the European market. EPCOS offers five versions, both horizontal and upright, encapsulated in plastic packages. This design has the great advantage of allowing simple modification. The chokes of the standard series can be adapted to special requirements on request by using ferrites with higher permeability values, total rather than standard-economy encapsulation as well as different numbers of windings.
Chokes with rated currents exceeding 8 A in open designs in which the wound toroidal core is attached to a baseplate are in demand for high power SMPS and for discrete suppression of interference from converters.
For SMPS transformer designs, a current-compensated choke is needed in addition to the transformer. The most important requirement on the choke is high inductance and compact dimensions. EPCOS offers miniaturised power chokes in two versions, both horizontal and upright. For customers who require complete surface mounting and processing for power chokes, EPCOS offers a power choke as an SMD.
Whereas toroidal cores can be assembled either only manually on more or less automated production units, the structure of the D-core chokes allows for fully automatic manufacture.
