Fixed inductors, commonly referred to as ‘chokes’, provide the necessary impedance for certain kinds of electrical devices, such as transformers, converters, and ballasts. Most inductors utilize a winding of some sort, usually a coil or a transformer, to generate an induced electric or magnetic field by flowing a current through it. Generally, the inductor designs are differentiated based on inductance, power needs, size, weight, temperature range, and flux. The NR4018T1R0N is an inductor especially tailored for specific applications.

Specifically, the NR4018T1R0N is a surface-mount fixed inductor composed of a ferrite core, self-supporting coils, and a rectangular or square-shaped body. The NR4018T1R0N is optimized for surface-mount assembly and is available in 18 sizes ranging from 1.0 µH to 390 µH. It is rated up to 6 Amps and works with 120 – 135 kHz frequencies. This inductor can also function up to a maximum operating temperature of 125 °C.

The applications of the NR4018T1R0N are well-suited to high-frequency, narrow-bandwidth applications, such as pulse generators, switching power supplies, computer power supply, stable system voltage regulators, and more. The NR4018T1R0N can also be used in low ripple current filtering, EMI, and RFI applications. In addition, the NR4018T1R0N is available with RoHS, Halogen-free, REACH, and EMI-conformant options making it one of the more versatile inductors on the market.

The NR4018T1R0N’s working principle is relatively straightforward. The currents, both steady-state and high-frequency, that flow through the inductors’ coils generate a magnetic field, this field in turn induces a current proportional to the magnitude of the magnetic field. The induced current opposes the original current, which creates a resistive opposition to any changes in the current through the coil. The resistive opposition, also known as the inductive reactance, enables the NR4018T1R0N to provide the necessary impedance to a particular circuit, thus allowing the device to work properly.

The NR4018T1R0N is a popular choice for fixed inductors due to its compact size, high performance, great reliability, and low EMI levels. Its extensive list of applications make it ideal for a wide variety of applications. This makes the NR4018T1R0N an excellent choice for engineers working on a range of different products.
