Abstract: PROBLEM TO BE SOLVED: To provide a magnetically coupled element that has a high coupling efficiency and small leakage inductance. SOLUTION: The magnetically coupled element MC1 is provided with a first conductor 1, a second conductor 11, and a magnetic material 21. The first conductor 1 is formed in a plate-like shape and has a square base 3 and terminals 5 extended from facing two sides of the base 3. The second conductor 11 is also formed in a plate-like shape and has a square base 13 and terminals 15 extended from facing two sides of the base 13. The magnetic material 21 is disposed to surround the first and second conductors 1 and 11. Depressed sections 25a are formed in portions corresponding to the space area between the terminals 5 and 15 of the surfaces of the magnetic material 21 from which the terminals 5 and 15 are led out by being notched so that the sections 25a are separated from the space area. Consequently, parts of surfaces of the lower magnetic material 25 of the magnetic material 21 from which the terminals 5 and 15 are led out are separated from the space area between the terminals 5 and 15.

Abstract: PROBLEM TO BE SOLVED: To furthermore improve heat dissipation of a core by extending a heat dissipation route of heat produced at an upper beam section. SOLUTION: In case when a lower beam section 11, an upper beam section 12, a main leg section 13, and a side leg section 14 are included and it is assumed that the cross section of the lower beam section 11 is S L , the cross section of the upper beam section 12 is S U and the cross section of the main leg section 13 is S M , respectively, the relationships of S L ≤S M /2≤S U and S L U are satisfied. Thus, the cross section of the main leg section 13 is ensured enough for a heat dissipation route from the upper beam section 12, so that heat produced in the upper beam section 12 can be effectively radiated to a base plate when a core is placed on the base plate. Furthermore, since the cross section of the lower beam section 11 is made small, a distance between the upper beam section 12 and the base plate is shortened, and heat produced in the upper beam section 12 can be effectively radiated to the base plate.

Abstract translation: 要解决的问题：通过延长在上梁部分产生的热量的散热路线来进一步改善芯体的散热。 解决方案：在包括下梁部分11，上梁部分12，主支腿部分13和侧腿部分14的情况下，假定下梁部分11的横截面为S
L ，上梁部12的横截面为S U ，主支腿部13的横截面分别为S M ，S L ≤S M /2≤S U 和S L U 满足。 因此，主脚部13的横截面被确保足够用于来自上梁部12的散热路径，使得当将芯放置在上梁部12上时产生的热能够有效地辐射到基板 基板。 此外，由于下梁部11的横截面小，所以上梁部12和基板之间的距离缩短，能够有效地将上梁部12产生的热量散发到基板。 版权所有（C）2009，JPO＆INPIT-
