Smaller size, stronger performance! Huacui empowers smart wearable devices with extreme lightness and thinness.

In the current trend toward product miniaturization, inductor sizes continue to shrink to meet the demands of consumer electronics, automotive applications, fast‑charging systems, and AI devices for slimmer form factors and higher integration. Meanwhile, advances in high‑permeability, low‑loss magnetic powders and high‑performance coil materials enable small‑size components to satisfy requirements for high current handling and low losses.

Reliability Testing of Inductance Values for Monolithic Inductors

Inductance is the ratio of the magnetic flux linked with a conductor to the current that produces that flux, when an alternating current flows through the conductor and generates an alternating magnetic field both within the conductor and in the surrounding space.

Definition and Variation of the Saturation Current of Monolithic Inductors

The saturation current of a monolithic inductor is defined as the current at which the inductance L decreases by 30% from its initial value. This current corresponds to the DC bias applied to the inductor. The relationship between the saturation current and the Hs (magnetic field strength) of a monolithic inductor is such that, in the initial portion of the powder‑material magnetization curve, the permeability μ remains relatively constant, and the inductance L varies only slightly with changes in the applied magnetic field. In the latter portion of the curve, however, μ increases significantly, and L becomes highly sensitive to variations in the applied field. For a given powder‑material system, the saturation flux density Bs is essentially constant; since Bs ≈ μ·Hs, it follows that Hs must also remain constant. Consequently, the larger the Hs, the smaller the slope of the hysteresis loop—indicating a more gradual change in μ—and the higher the saturation level.

Monolithic inductors effectively enhance the performance of electronic products.

An integrated‑molded inductor is a type of packaged inductor that has been optimized through design improvements. It features a toroidal soft magnetic core with a steel insert, coated with an insulating layer, and then formed via high‑pressure molding. This process integrates the inductor and the insulating material into a single, monolithic structure, resulting in a fully encapsulated electronic component.

Definition and Variation of the Saturation Current of Monolithic Inductors

Definition of the Saturation Current for Monolithic Inductors Here, the saturation current refers to the current at which the inductance L decreases by 30% due to magnetic saturation; this current is determined under an applied DC bias. Relationship Between Saturation and Hs in Monolithic Inductors In the initial portion of the powdered‑material magnetization curve, the permeability μ remains relatively stable, and the inductance L varies only slightly with changes in the applied magnetic field strength. In the latter portion, however, the permeability μ increases significantly, causing the inductance L to vary more markedly with changes in the applied magnetic field strength.
