The HCET series inductor is made by winding ordinary enameled wire or high-temperature enameled wire directly on a rod-shaped magnetic core. The coil body is dipped in glue (varnish) and the pins are tin-plated.It adopts high-current design to adapt to high-current circuit boards. It has the advantages of small size, light weight, solid structure (vibration resistance, impact resistance), good moisture resistance, easy installation, and diversified specifications to choose from.It is widely used in noise filtering of power supplies, power amplifiers, switching circuits, controlled rectifiers and thyristor control circuits, and output chokes.
