Problems solved by technology

Due to the factor of the magnetic core, in order to obtain a larger inductance, the volume of the magnetic core needs to be increased. In this way, the volume of the entire filter inductor is increased. On some small-volume (such as LED lights) loads It is difficult to assemble, therefore, it is necessary to reduce the size of the filter inductor to meet the usage requirements

Abstract

The invention discloses an ET type filter inductor. The ET type filter inductor comprises a magnetic core, a framework, an enameled wire and pins. The two ends of the magnetic core and the two ends of the framework are connected through glue. The enameled wire is wound around the framework. The pins are arranged at the end of the framework. The magnetic core is made of ET24R10K. The framework is made of ET24PBT. The ET type filter inductor further comprises a base. The base is located at the end of the magnetic core and fixedly connected with the magnetic core. The pins are located at the lower end of the base. The maximum total length of the magnetic core is not larger than 34 mm. The ET type filter inductor is simple in structure, the size of the magnetic core is small, and the maximum resistance is not larger than 0.8 ohm. The maximum withstand voltage between coils and between the coils and the magnetic core is 1000 VAC / 1 min / 10 mA.

Description

technical field [0001] The invention relates to the technical field of inductors, in particular to an ET type filter inductor. Background technique [0002] Filter inductors generally use ferrite materials, which can be easily combined with feedthrough capacitors to form a composite filter. In high-performance filters, wire-wound inductors are also used. Ferrite material will be magnetically saturated under high current, reducing filter performance. [0003] At present, most filter inductors are composed of magnetic cores, enameled wires and pins, and the magnetic cores are made of ferrite cores. Due to the factor of the magnetic core, in order to obtain a larger inductance, the volume of the magnetic core needs to be increased. In this way, the volume of the entire filter inductor is increased. On some small-volume (such as LED lights) loads It is difficult to assemble, therefore, it is necessary to reduce the size of the filter inductor to meet the usage requirements. ...
