Fixed Inductors

Fixed inductors are electrical components with inductance values that remain constant as opposed to variable inductors (such as potentiometers and trimmer inductors). The most common type of fixed inductor is a printed circuit board component composed of an inductor winding, a magnetic core, and connection leads. Fixed inductors are used in radio frequency and power supply applications.

0805-3N0J Application Field and Working Principle

The 0805-3N0J fixed inductor is a monolithic surface-mount inductor available with a variety of case sizes and coil values. It is specifically designed for applications where low power dissipation, low DC resistance, and small size are critical features. The 0805-3N0J offers an inductance range of 1.2 to 39.2uH and a terminations size of 0.08 inch (2.0 mm).

The 0805-3N0J fixed inductor uses a winding of conductive material as an inductor core. Upon application of alternating current (AC), the winding generates a magnetic field in the core. This magnetic field induces a current in the winding, which creates an impedance in the circuit and reduces the amplitude of numerical values of the AC. The amount of impedance in the circuit depends upon the inductance value of the inductor, the number of windings, and the size of the core.

The 0805-3N0J is primarily used in radio-frequency (RF) applications, such as radio receivers and wireless systems. It is also used in power supplies, where its low resistance and small size makes it an ideal choice for high-frequency switching power supplies. In pulsed power applications, such as dc-dc converters and drop-out regulators, the 0805-3N0J reduces the switching noise while preventing the power surges that can cause device failure.

The 0805-3N0J fixed inductor’s main advantages are low power dissipation, low DC resistance, and small size. It is designed to minimize current saturation at high frequencies, and it is available with a variety of case sizes and inductance values. With its small size and low profile, it is ideal for applications where board space is limited.

The 0805-3N0J is a reliable, high-performance inductor solution for a variety of applications. It is an ideal choice for radio-frequency, power supply, and pulsed power applications where component size and power dissipation are critical factors. Its low resistance and small size make it suitable for a variety of applications where space is limited.
