After winding, the inductor needs to undergo high-temperature aging treatment to eliminate residual stress between the windings.
Magnetic ring filter inductors—typically composed of a toroidal core made of ferrite material and a through-wire—effectively suppress the propagation of high-frequency noise without the need for an external power supply or complex circuitry, thanks to the
In the context of modern electronic devices increasingly pursuing thinness, efficiency, and intelligence, switching power supplies have become the "heart" of almost all electrical products.
As a key passive device for suppressing electromagnetic interference, magnetic ring filter inductors must balance high-frequency noise suppression and high current carrying capacity within a limited space. The saturation current—the DC bias current when t
In the trend of modern electronic devices increasingly pursuing miniaturization, high density, and high reliability, passive components, though not as eye-catching as chips, play an indispensable role in key aspects such as power management, signal filter
In modern power electronic systems, high-frequency transformers, as core components for energy transfer and electrical isolation, directly determine the efficiency, size, and reliability of the power supply.
