The material of the magnetic core has high initial permeability, low coercivity and loss, and stable magnetic performance, but the Bs is not high enough. When the frequency is greater than 20kHz, the
In recent years, a new type of low-cost and high-quality interference suppression device has been developed. Its function is equivalent to a low-pass filter, which can better solve the problem of high
The magnetic ring is not so magical as it is said. It is only necessary to match what kind of magnetic ring according to the characteristics of the product. The size and characteristics of each magnet
For soft ferrite, it is generally desirable that the permeability μi and the resistivity ρ be high, and the coercivity Hc and loss Pc are low. Depending on the use, there are also different requiremen
Ferrite toroidal inductors are divided into manganese-zinc ferrite toroids and nickel-zinc ferrite toroids. According to the different materials used, the calcined materials are different. The nickel-
Most of the magnetic rings must be painted. Generally, the manganese zinc ring is painted green, and the iron powder core ring uses two colors to distinguish the raw materials. Commonly used are -2 (r
