Embodiment Construction
[0017] A multilayer chip filter, such as figure 1 As shown, it is composed of multilayer chip capacitors and multilayer chip core inductors, and has a multilayer chip structure. The multi-layer chip core inductor is formed by stacking and sintering ferrite diaphragms with conductor lines printed on the surface of multiple layers. The conductor lines on the surface of the multi-layer ferrite diaphragms are connected to each other and form an inductance coil. The inductance coil One lead-out end is connected to one end electrode of the whole filter, and the other lead-out end is connected to the other end electrode of the whole filter. The laminated chip capacitor includes two terminal electrode plates and a ground electrode plate, wherein one terminal electrode plate is connected to one terminal electrode of the whole filter, and the other terminal electrode plate is connected to the other terminal electrode of the whole filter, The ground electrode plate is connected to the g...
