Fixed Inductors

Fixed inductors are used for a variety of applications, including power supplies, transformers, and amplifiers. They are usually composed of coils of wire that form an inductor coil, and they can be either fixed or adjustable. Depending on the type of inductor selected, its application can range from high-frequency switching to low-frequency filtering.

The 0805-621K application field and working principle specifically refers to a specific type of fixed inductor. This type of device uses a 3-terminal package, with a lead-free and RoHS-compliant construction and a shielded design. It operates with a voltage rating of 100 to 500 volts, a temperature range of -55 to +125°C, and an operating frequency of up to 2.5 GHz. It is designed for EMI/RFI suppression and is recommended for use with switching power supplies, inverters, and motor controllers. It has a rated inductance of 6.2 µH at a rated current of 0.2 A.

The working principle of the 0805-621K is based on the idea that a current passing through a coil of wire generates a magnetic field. This magnetic field induces a voltage to be generated in the adjacent windings of the coil. The voltage created in the adjacent windings is inversely proportional to the inductance of the coil, and it is also proportional to the rate of change of the current. Therefore, if a large amount of current is flowing through the coil, the induced voltage will be high, and if the current is reduced, the voltage output will be lower.

The 0805-621K is designed to offer a stable, low-impedance frequency response in the range of 100 kHz to 2.5 GHz. It is suitable for use in various applications where noise suppression is required, such as automotive systems, communication systems, and computer peripherals. This type of inductor is designed to provide high-current EMI/RFI performance, and it is particularly useful for applications that require a low-noise filter.

The 0805-621K is a reliable and effective way to reduce noise in a variety of applications. It is offered in a lead-free and RoHS-compliant package that is simple to install and offers excellent performance. This type of inductor is widely used for a variety of applications, including power supplies, transformers, and amplifiers, and is a reliable choice for both commercial and industrial uses.
