Fixed inductors are electrical components with the primary purpose of creating a stored magnetic field. An overview of the HCM1A1707-4R7-R fixed inductor and their application field and working principle will be discussed in the article.

The HCM1A1707-4R7-R fixed inductor is composed of a magnetic core core material and multiple winding. The materials used in the core material is Ni-Zn ferrite, which is a ferrite material of which the main component is zinc and nickel oxide, while the winding is made of copper wires. This fixed inductor has a tolerance of ± 10%, an inductance of 4.7mH, a current rating of 4.15A and an interwinding capacitance of 18pF.

The HCM1A1707-4R7-R fixed inductor is primarily used in switching power supplies, especially in switching power supplies that require a higher output power, and can also be used in synchronous rectification, resonance circuit, low-frequency inductors, DC to DC converters, DC-DC converters, DC-AC converters, and many other applications. This inductor extends the switching power supply’s response time, increases the power efficiency, eliminates AC power input distortion, and reduces THD (total harmonic distortion).

The working principle of an HCM1A1707-4R7-R fixed inductor is quite simple: the current flows through the winding of the inductor and creates an EMF field (electromagnetic wave field) that is proportional to the rate of change of the current. The EMF interacts with the magnetic core material, resulting in a stored energy field. The magnitude of this stored energy field is proportional to the strength of the EMF. When the current stops, the stored energy field will then dissipate and be released in the form of a current.

In conclusion, the HCM1A1707-4R7-R fixed inductor is primarily used in applications requiring higher output power such as switching power supply, synchronous rectification, and resonance circuit. Its working principle involves having a current flow through its winding to create an EMF field, which is then stored in the core material. This stored energy field can then be dissipated and released in the form of current.
