HCM1A1305-4R7-R is a kind of fixed inductor produced by Vishay Intertechnology. This device has a variety of applications in various fields due to its low profile (2.3 mm) and wide range of inductance values (4.7uH±20%). Here, we will discuss its application field and working principle.The HCM1A1305-4R7-R is widely used in DC output filters or buck converters. It is suitable for switching power supplies, battery charging, and other power electronic applications. This inductor provides sufficient current for changes in a light load and can be sued in low voltage applications.The working principle of the HCM1A1305-4R7-R is based on the law of induction. When a changing electric current passes through a conductor, a magnetic field is created around the conductor. This magnetic field will induce a potential difference in the same conductor, which will result in an opposing current to the initial current. This phenomenon is called electromagnetic induction.The core material of the inductor will affect its working performance. Soft ferrite core is used in HCM1A1305-4R7-R, which gives it better performance when it is used in switching mode power supplies. The ferrite core minimizes power loss, while still providing high switching current.The coil windings of the HCM1A1305-4R7-R are wrapped with enameled copper wire. This is to protect the inductor from external electric shock and minimize the losses generated in the electromagnetic field. An air gap is also added between the windings to reduce the losses caused by a parasitic capacitance.Besides, the package of HCM1A1305-4R7-R is specially designed using surface mount technology. It is in a square shape that can be mounted on a variety of boards. Its high stability and low profile allows it to be mounted in various location with minimal occupied space.In conclusion, the HCM1A1305-4R7-R is a versatile fixed inductor which has many applications in power electronic, battery charging, and DC output filters. It has an improved design in terms of its core material, coil winding, and package. This ensures that it can deliver high quality and stability performance.
