摘要： 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.

摘要： A composite electronic component composed of a composite body including a capacitor and an electrostatic discharge (ESD) protection device coupled to each other. The capacitor includes a ceramic body in which a plurality of dielectric layers and internal electrodes are stacked with a respective dielectric layer therebetween. The ESD protection device includes first and second electrodes disposed on the ceramic body, a discharging part disposed between the first and second electrodes, and a protective layer disposed on the first and second electrodes and the discharging part. An input terminal disposed on a first end surface of the composite body and is connected to internal electrodes and the first and second electrodes. A ground terminal formed on a second end surface of the composite body and is connected to internal electrodes and the first and second electrodes.
