Kind Code:
B2
Abstract:
PURPOSE:To enable suppression of heat generation in a choke coil by specifying diameters of wires which are wound around ferrite magnetic cores in a choke coil. CONSTITUTION:Wires 2a and 2b of 4mm to 1.6mm in diameter are wound around ferrite magnetic cores 1a and 1b of 7mm to 10mm in diameter, respectively, so as to form a choke coil. A cross section of this core is 40mm<2> to 70mm<2>. One-sided ends of these coils are connected with electrodes 4a and 4b of a through-type capacitor 3, and the other-sided ends of them are connected with heater electrodes 5a and 5b. Hence, heat generation in the choke coil can be suppressed even if the coil is used at a high frequency of several tens of KHz.
