What is a chip inductor? What types?

Chip inductors are also called surface mount inductors. Like other chip components (SMC and SMD), they are a new generation of leadless or short-lead micro electronic components suitable for surface mount technology (SMT). The welding surfaces of the lead-out ends are on the same plane.

There are four main types of chip inductors, namely wire-wound type, laminated type, braided type and film chip inductor. Among them, the wire-wound type is the miniaturization of traditional wire-wound inductors, while the laminated type is produced using multi-layer printing technology and lamination production technology. It is smaller than the wire-wound chip inductor and is the focus of the field of inductance components. developed products. Current status and development trends of chip inductors. It is difficult for micro inductors to achieve sufficient inductance and quality factor (Q). At the same time, the circuit and magnetic circuits in magnetic components are intertwined and the manufacturing process is relatively complex. Therefore, as the three major foundations The inductor, one of the passive components, has become chip-based, significantly lagging behind capacitors and resistors.
