Multilayer filter

摘要

Input-output terminal electrodes 3 and 4 are overlaid in both respective edge faces of the multilayer body 1 of a multilayer filter. Ground electrodes 5 and 5 are overlaid on both respective sides of the multilayer body 1. Through-hole electrodes 16 and 17 for use as a pair of inductance elements are formed in the multilayer body. One ends of the inductance elements are each electrically coupled to the input-output terminal electrodes 3 and 4, the other ends being connected to the conductive layer formed as a sealed electrode 21. Paralleled capacitators connected to the inductance elements are formed in the multilayer body 1. The ratio W/d of the diameter d of the through-hole electrodes 16 and 17 to width W between the ground electrodes 5 and 5 on both edge faces of the multilayer body 1 is set at not less than 1.6 and not greater than 11.4. <IMAGE>
