Why are most of the on-board inductors magnetic bar inductors | GETWELL

Inductors can be divided into many kinds according to the shape of the magnetic medium, among which ferrite bar coil is the most common inductor. The following professional ferrite bar coil manufacturers will reveal why ferrite bar coil is used as the inductor of the vehicle.

Ferrite bar coil inductor is cylindrical magnetic rod, open magnetic circuit structure, long magnetic circuit, low inductance, not easy to saturate, superposition large current, reduce current failure.

In the circuit application, it is reflected as follows: long time overload current, no heating, stable inductance, maximum superposition of 50A current, thick wire diameter, belonging to the strongest current resistance among all inductors.

However, the ferrite bar coil is usually wrapped in a single layer tightly, and the inductance is usually several uH, which cannot provide a large inductance. However, some on-board control components, such as igniter, rectifier, etc., are used for filtering, choke, DC-DC boost/buck, and circuit oscillation, which do not require a high inductance, just a few uH.It is a perfect match with the characteristics of ferrite bar coil, and the most important thing is that the on-board inductor has a high requirement for the safety and stability of electronic components. Even though the inductor has the same inductance, the conventional inductor cannot be guaranteed to work stably over current for a long time due to the lack of ferrite bar coil's super resistance to current.And the ferrite bar coil is small in size and takes up less space.

Fe-Si coil inductors are also used in vehicle inductors, but to replace ferrite bar coil inductors, a larger Fe-Si coil inductor is needed to ensure the same resistance to current. The manufacturing cost is much higher than that of ferrite bar coil inductors, because the inductance range of Fe-Si coil inductors is larger.Closed magnetic circuit structure, and anti-interference effect.
