Document Type and Number:
Japanese Patent JPH0822926
Kind Code:
A
Abstract:
PURPOSE: To realize a DC applying transformer, which is good in lowpass characteristics and is stable in characteristics.
CONSTITUTION: Opening end parts 10a and 10b formed in a bobbin 10 are filled alternately with E cores 12 in the order of 3 sheets, 6 sheets, 6 sheets and 4 sheets. As the material for the E cores 12, a PC material having a high content of nickel is used. As the PC material is used as the material for the E cores 12, the characteristics of a DC applying transformer are stabillized and at the same time, as the filling of the E cores 12 in the order of the 3 sheets, 6 sheets, 6 sheets and 4 sheets is conducted, the low-pass characteristics of the transformer are improved.
