Fixed Inductors

Inductors are electronic components which store energy in the form of a magnetic field. The Fixed Inductors are basically wound wire coils which have a fixed inductance. This means that the inductance does not change with time or frequency. Fixed Inductors are the most common type of inductor and are generally used for filtering purposes or in high-frequency applications.

The UPO.4UC-331-R is a high-saturation, large-current type, Fixed Inductor from Panasonic Open-Air and Halogen-Free Series. This product has a wide rated DC current range of 8.0A to 16.0A and a high-saturation current rating of 250% of the rated current. It is suitable for power circuits requiring high-performance such as LED lighting, Automotive, etc. Since its Nominal inductance is 3.3uH, it is not suitable for high frequency applications.

The application fields of the UPO.4UC-331-R include direct DC-DC converters, DC-AC inverters, and high power switching power supplies. This Fixed Inductor is also used in LED lights and other high power-consumption lighting applications, as well as for automotive applications.

The working principle of the UPO.4UC-331-R follows, the same as other Fixed Inductors. When AC or DC current flows through a wire coil, a magnetic field is produced. This magnetic field actually resists the change in the flow of current and this resistance is called inductance. The more turns a coil has, the greater the inductance. In the case of the UPO.4UC-331-R, its high saturation current rating is due to its large diameter, which results in a greater number ofwire turns.

In summary, the UPO.4UC-331-R is a type of Fixed Inductor from the Panasonic Open-Air and Halogen-Free series which has a wide rated DC current range and high-saturation current rating. The application fields of the inductor include LED lighting, Automotive, Direct DC-DC converters and DC-AC inverters. The principle of working is the same as other Inductors. When current flows through a wire coil, a magnetic field is produced which resists the change in the flow of current.
