Profile: Magnetic Circuit Elements (MCE) designs and manufactures miniature transformers & inductors for military, medical, solar inverters, telecommunications, and test equipment. This includes an extensive line of standard parts, modified standards and custom parts. The E-core chokes are both the ODBL & OCBL series filter chokes that are offered for use in high-frequency DC power supply applications including switching regulators, flyback circuits, and solar inverters. It features PC bobbin or self leads, ferrite E-cores, and open type construction. The flyback transformers can accommodate a wide range of input voltages. For those applications that have relatively small tolerances of input voltages such as the 48 Vdc bus. Push-Pull transformers have certain advantages such as approximately twice the power handling capability for the same size of the flyback. The small filter input chokes attenuate the output ripple current allowing the use of less expensive capacitors with lower ripple current ratings. The push-pull transformers can also provide much larger power ratings with less EMI and efficiency.
