Abstract
An inductor includes first and second coil patterns disposed in a single chip, and at least one common lead terminal electrically connected to respective end portions of the first and second coil patterns. The first and second coil patterns operate independently of each other, such that a range of a current passing through the first coil pattern and a range of a current passing through the second coil pattern are different from each other. The first and second coil patterns are coil patterns having different electrical characteristics.
Claims24
An inductor comprising:
- a first coil pattern including a first end portion and a second end portion electrically connected to the first end portion;
- a second coil pattern including a third end portion and a fourth end portion electrically connected to the third end portion;
- a first lead terminal electrically connected to the first end portion of the first coil pattern;
- a second lead terminal electrically connected to the third end portion of the second coil pattern;
- and
- a common lead terminal electrically connected to both the second end portion of the first coil pattern and the fourth end portion of the second coil pattern,
- wherein an inductance value of the first coil pattern is greater than that of the second coil pattern, and
- a direct current (DC) resistance value per unit length of the first coil pattern is greater than that of the second coil pattern.
An inductor comprising:
- a first coil pattern electrically connected between a first lead terminal and a common lead terminal;
- a second coil pattern electrically connected between a second lead terminal and the common lead terminal;
- wherein an inductance value of the first coil pattern is greater than that of the second coil pattern, and a DC resistance value per unit length of the first coil pattern is greater than that of the second coil pattern.
An inductor, comprising:
- a first coil pattern electrically connected between a first lead terminal and a common lead terminal;
- a second coil pattern electrically connected between a second lead terminal and the common lead terminal;
- wherein a cross-sectional area of the second coil pattern is greater than that of the first coil pattern.
