PA4342.822NLT Inductors, Coils, Chokes

Fixed inductors are passive electrical components used in various types of electronic circuits. The most common types of fixed inductors are air core inductors, toroidal inductors, and wound inductors. In order to meet the different design needs of various electronic products, magnetic core type inductors are also available. One of the most popular housings for inductors is the PA4342.822NLT, a surface mount inductor coil specifically designed for the RF/microwave market. This article will explain the application field of the PA4342.822NLT, as well as the working principle behind it.

Application Field

The PA4342.822NLT inductor is a surface-mount RF/microwave inductor designed for use in high-frequency circuits. It is ideal for applications where high standards of quality and reliability are essential. Due to its small size, the PA4342.822NLT is especially well-suited for use in applications where board space is at a premium. Potential applications include high- frequency wireless communication systems, laptop antenna systems, base stations, antenna couplers, RFID systems, microwave radios, and medical equipment.

Working Principle

An inductor is a passive electronic component that stores energy in a magnetic field created by an electric current. When a current passes through an inductor, the magnetic field created helps maintain the current and resist any changes in the amount of current. This is known as inductance, which is measured in henries (H).

The PA4342.822NLT is a surface-mount RF/microwave inductor with an inductance of 0.22 microhenries (µH). It has a very low DC resistance of 0.04 ohms (Ω), and is rated to a maximum current of 105 milliamps (mA). It also has a maximum operating frequency of 4.2 GHz.

The inductor is constructed using two pieces of magnetic core material, one for the body and one for the lid. The body is made from a ferrite material, while the lid is made from a high-temperature, high-permeability material. These materials are chosen for their ability to reduce losses at high frequencies.

The inductor also utilizes winding technology to ensure that inductance remains stable over a wide operating temperature range. This winding technology is then protected by an epoxy-glass package that helps ensure the inductor remains small and lightweight while ensuring reliable performance.

Conclusion

The PA4342.822NLT is a surface-mount inductor coil specifically designed for the RF/microwave market. It has a high inductance of 0.22 µH, a low DC resistance of 0.04 Ω, and a maximum operating frequency of 4.2 GHz. It is ideal for applications with space constraints, and can be used in high-frequency wireless communication systems, laptop antenna systems, base stations, antenna couplers, RFID systems, microwave radios, and medical equipment. The inductor is constructed using winding technology and two pieces of magnetic core material, and protected by an epoxy-glass package.
