distinguish

-Appearance and shape: the patch inductor is usually flat, such as rectangular or square, with no pins or short pins; The inductance of the plug-in is generally cylindrical or I-shaped, with long pins.

-installation method: the patch inductor is directly welded on the surface of PCB by surface mounting technology; Plug-in inductance is fixed by inserting the pin into the jack of PCB board.

-size: the patch inductor is small in size and light in weight, which can save PCB space; Plug-in inductance is relatively large and takes up more space.

-inductance range: the inductance range of plug-in inductance is wide, reaching hundreds of Henry; The inductance of the patch inductor is generally between a few nanohens and a few microhens.

-High-frequency characteristics: the self-resonant frequency of the patch inductor is high, and the high-frequency performance is good; The self-resonant frequency of plug-in inductance is low, and its performance in high frequency circuit is relatively poor.

-Production technology: The production technology of patch inductor is complex, requiring precise equipment and technology; The plug-in inductor has simple structure and relatively easy production process, and can be produced manually or automatically.
