Fixed InductorsFixed inductors, also known as chokes, are passive components used in power supplies and other electrical circuits, to store and release energy in the form of a changing magnetic flux field. In general, they consist of a coil of insulated wire, wound around a magnetically permeable core. The core is magnetically conductive and allows the magnetic field lines of the coil to pass through, thereby increasing inductance.The NRS8040T470MJGK is an example of such a component. It falls into the category of radial-leaded power factor correction (PFC) fixed inductors, which are used with PFC circuits in DC/DC power supplies, switch mode power supplies, and motor drives.In operation, the PFC inductor is placed in series with the line voltage source, acting as an EMI filter to reduce injected noise at the supply terminal. The purpose of the inductor is to draw a current in phase with the applied voltage, increasing the power factor of the input power to the power supply. This increases the line input current in response to the load current demand, resulting in improved power efficiency.The NRS8040T470MJGK PFC inductors have a small size, low profile, and high power rating, making them suitable for high density power supplies. The inductors are designed with a ferrite core for stability and reliable operation in a wide range of temperatures, up to 120°C. The NRS8040T470MJGK PFC inductors also have a good tolerance to higher temperatures than other types of inductor. They feature a maximum operating frequency of 1MHz, and have a current rating of 10A and an inductance range from 0.47 to 5μH. The other features of the NRS8040T470MJGK include a small footprint size of 6.3mm x 11.3mm, low DC resistance, low core loss, high DC bias voltage, and fast heat dissipation for high power output. The inductors are also lead-free products, so they are environmentally friendly.NRS8040T470MJGK PFC inductors can be used in a variety of applications, including medical devices, telecommunications equipment, power supplies, UPS, and consumer electronics. They are also used in a variety of high power switching applications, such as voltage converters, lighting inverters, motor drives, and AC/DC converters.In summary, fixed inductors like the NRS8040T470MJGK are devices used in power electronic systems, for efficient power conversion and noise reduction. They are made from magnetically permeable cores and wire coils, and are rated for high operating temperatures. With its small size, high power rating, and environmental friendliness, the NRS8040T470MJGK is a popular choice for various power management applications.
