Abstract:
An inductance device comprises a magnetic core, a coil a conductor and a dielectric member. The coil is made of turns of insulated conductive wire. The conductor is distinct from the coil and is insulated from the magnetic core. The dielectric member is disposed between the conductor and the coil. The dielectric member, the conductor and the coil constitute a capacitor. The inductance device is used in, for example, a filter device or a noise filter.
