Title:
LAMINATED IMPEDANCE DEVICE
Document Type and Number:
Japanese Patent JPH0661053
Kind Code:
A
Abstract:
PURPOSE: To obtain a device showing noise reduction effect by providing a conductor part opposite a conductive pattern via a magnetic material in a magnetic material.
CONSTITUTION: A conductor part 5 is formed opposite a conductor pattern 3 which forms a coil 4 in a magnetic material 2, and its one end 5A is connected to an external terminal 6. Thus, the capacitance of the capacitor 8 is connected in parallel with the resonance circuit of an impedance device to make the resonance frequency f of the impedance device move to low frequency side, so that ideal impedance characteristics can be obtained.
