Fixed inductors are divided into three types according to the structure of the core: iron core, ferrite core and air core, the four types are divided according to the winding method: fixed type, sucking type, removable type and high frequency type. Among them, the winding type of 4470-05F is fixed type, and the material of the core can be air core or high frequency alloy ferrite core according to the needs.

The 4470-05F is based on the principle of the current-dependent choke coil to fix the inductance. At this time, it is within the applicability range of the inductance. Only when the current increases to a certain value, the inductance will increase. Therefore, it can be used as a protection in some circuits with overcurrent to protect them from being damaged.

In terms of applications, 4470-05F is mainly used for circuits such as filter circuits, oscillation circuits, overcurrent protection circuits, and nuclear magnetic resonance circuits. For example, the overcurrent protection circuit exactly uses the change of the inductance when the overcurrent occurs, and the inductance increase will cut off the current path. In the oscillation circuit, in fact, the principle of the capacitor will oscillate, so that the current loop can be currents in a period of time.

The inductance of the 4470-05F fixed inductor itself has two basic discharge modes: one is Ohm\'s law discharge mode, that is, according to the requirements of the circuit design, the inductance calculates the current flow under the given frequency, and then calculates the self-inductance required for the circuit; The second way is time-constant discharge mode, which is to determine the inductance according to the resistance of the discharge current.

The construction of 4470-05F generally includes the winding structure of the coil and the structure of the formulation of the coil. The current-dependent choke coil usually adopts an electrical formula composed of an inductor, a resistor, and a capacitor. They can be combined together, and the impedance of the circuit can be adjusted by changing the parameters of the inductor to achieve the desired effect.

The material of the core of the 4470-05F depends on the characteristics of the inductance, quantity, range, etc. of the product. Air core and high frequency alloy ferrite core is generally selected. The 4470-05F fixed inductor is generally equipped with a shell, otherwise the connection will be too complicated. Generally, the shell is made of iron or aluminum alloy with appropriate thickness, which can withstand vibration, shock and other conditions.

In summary, the 4470-05F is a type of fixed inductor, using the current-dependent choke coil to fix the inductance, and its core material is generally air core or high frequency alloy ferrite core. It is mainly used for circuits such as filter circuits, oscillation circuits, overcurrent protection circuits, and nuclear magnetic resonance circuits. The materials and structures of the core and casing of the product are also carefully designed to ensure the good performance of the product.
