Fixed inductors generally refer to components with an inductance that can remain constant when the current and frequency change. Fixed inductors are widely used, mainly for smoothing in power supply circuits, high-frequency bypass, filter impedance matching in communication circuit, radio frequency shielding, and so on. The SC3DF-1R5 is a common fixed inductor that is widely used to enhance the performance of electronic components and thermal stability.

The SC3DF-1R5 fixed inductor is a chip inductor, which also is an inductor with a small size in surface mount technology (SMD) package. It has a disk shape with an overall height of 2.1mm. The inductance of the component is 1.5uH, with a maximum DC current of 1.0A, indicating a rated DC current of 0.2-0.4 A and an operating temperature range of -55 to +125C. The operating voltage range for the SC3DF-1R5 is 1-20V, with a typical SRF of 63MHz. The inductance tolerance is +30%, and the self-resonant frequency is 6.3MHz.

The SC3DF-1R5, like other fixed inductors, has an inductor core comprised of a coil of wire and a magnetic core. The electrons in the wire coil produces a magnetic field, which induces electric currents in the surrounding area. This core is wrapped with an insulating material, usually plastic or rubber. The core and the insulation material are then sealed in a housing, made of either plastic or metal.

The fixed inductor can store energy in the form of a magnetic field when electric current flows through it. When the electrical current passes through the winding, a magnetic field is created, which causes the electrons in the winding to move in a circular motion. This circulating current produces a magnetic field, characterized by an inductance value, which in this case is 1.5uH. The magnetic field around the winding is maintained as long as the current is in the same direction, and does not decrease if the current polarity changes.

The main application field of the SC3DF-1R5 fixed inductor is generally in the field of radio frequency (RF) circuits, but it can also be used in electronic circuits such as DC/DC converters, rectifiers, switching power supplies, and low dropout (LDO) regulators. It is commonly used as an inductor in oscillator circuits, voltage regulator modules (VRM), and other similar electronic devices.

The inductor is also an important component in many communication systems, such as cellular, Wi-Fi, and Bluetooth, to aid in frequency modulation and amplitude response. In automotive electronic systems, such as engine control, fuel injection, and brake control, the SC3DF-1R5 is used for signal and noise filtering, allowing signals to be transmitted more clearly. Additionally, it can be used in such industries as industrial automation, medical technology and the military, where it is necessary to keep the circuits free of noise and interference.

The SC3DF-1R5 is also a component widely used in electrically shielded enclosures to absorb external EM/EMI radiation, as the shielding material may not be enough to completely protect the circuits. It can be used to reduce the strong radiation by absorbing and reflecting the radiation instead of transmitting it, thus improving system performance.

Thus, the SC3DF-1R5 fixed inductor is a versatile component widely used in many industries like automotive, communications, military, industrial automation, and medical, etc., to improve system performance and provide sufficient signal and noise reduction. Its typical operating voltage range and inductance tolerance are 1-20V and +30%, respectively, and its typical SRF is 63MHz.
