Abstract

PURPOSE:To obtain excellent frequency characteristic and high voltage pulse noise characteristic by utilizing an amorphous alloy having pulse permeability, saturated magnetic flux density and saturated magnetic field in such values larger than the specified value and thickness in a value smaller than the specified value as the core. CONSTITUTION:A high voltage puse characteristic which is more excellent than that of ferrite can be obtained by utilizing amorphous alloy as the magnet core, which has pulse permeability mup of 2,000 or more, Bs>=5,500G or more and saturated magnetic field Hk of 10e or more when being excited under the condition, DELTAB=5,000G and pulse width is 5mus,. In the case of amorphous ferro-magnetic alloy, from the point of view of frequency characteristic, thickness of ribbon must be set to 0.025mum or less in order to obtain the frequency characteristic which is the same as that of ferrite for power supply line filter because of a large effect of eddy current. An inductor for power supply line filter using such core is excelent in the frequency characteristic and shown large attenuation for a high voltage pulse noise.

８１．１が小さくなってしまう。Conventionally, ferrite, powder magnetic cores, and silicon steel plates have been used as inductor magnetic cores for power line filters. It's promising, but the saturation magnetic flux density is 50,000F? It has little effect on high voltage pulses due to its low power. On the other hand, powder iron cores and silicon steel plates with high saturation magnetic flux density do not have sufficient frequency characteristics of magnetic permeability |■|
