Composite electronic component and board for mounting thereof

A composite electronic component comprising:

• a composite body including a capacitor and an inductor coupled to each other, the capacitor being configured of a ceramic body including a plurality of dielectric layers and first and second internal electrodes disposed to face each other with a respective dielectric layer interposed between the first and second internal electrodes are stacked, and the inductor being configured of a magnetic body including a coil part;
• an input terminal formed on a first end surface of the composite body and connected to the coil part of the inductor;
• an output terminal including a first output terminal formed on a second end surface of the composite body and connected to the coil part of the inductor and a second output terminal formed on the second end surface of the composite body and connected to the first internal electrode of the capacitor;
• and
• a ground terminal formed on one or more of upper and lower surfaces and a first end surface of the capacitor in the composite body and connected to the second internal electrode of the capacitor,
• wherein the capacitor is coupled to a side surface of the inductor, and the sum of ratio of lengths of a short axis to a long axis of the coil part is more than 0.7 and less than 1.0, and
• a direction of a magnetic flux of the inductor is parallel to surfaces of the first and second internal electrodes disposed in the capacitor.
