<p>PURPOSE:To effectively suppress an electric wave interference by making all parts or a part of an electric wire inserted or wound to a magnetic core into a resistor. CONSTITUTION:Into the central hole of ferrite beads 1, a resistance wire 2 having a necessary resistance value is inserted, plural filters 4 to connect an L-shaped terminal 3 are arranged in parallel to a constant interval at both edges, and faced by a resin molding as shown by a chain line. The filter 4 has an equivalent circuit to connect serially the inductance and resistance, and when the filter is connected to the signal line of a cable, the rise of the signal pulse is made dull, the electric wave interruption is suppressed, and the generation of the pulse oscillation is also suppressed. Since wiring is short, the radiation of the interruption wave from the wiring can be minimized and consequently, the electric wave interference based on the connection of equipment can be low suppressed.</p> |
