Fixed Inductors

Inductors are the simplest form of electrical components that construct electrical circuits. In electrical engineering, a fixed inductor is a passive component that stores magnetic energy in its magnetic field and, along with resistors and capacitors, is fundamental in electrical circuits. The terms inductor, coil and choke are often used interchangeably. The difference between a coil and an inductor is that a coil is electrically in series with an energy source, while an inductor is not. One of the most common types of fixed inductors is the 160R-820KS, which is used in a wide variety of applications. This article will discuss the application field and working principle of the 160R-820KS.

Application Field

The 160R-820KS is a type of radial-type fixed inductor features small size, low DC resistance, low cost and high performance. It is designed for use in high-frequency applications, such as power supplies, power converters, switching power supplies, communication systems, mobile phones, automotive electronics, and industrial equipment. The 160R-820KS is suitable for applications that require high current density and low-profile form factor such as switching regulators, mobile phone chargers, and power inverters. The device also features high efficiency and high power density, making it ideal for applications in portable electronics.

Working Principle

The 160R-820KS fixed inductor is an air-core coil wound on a specially designed winding drum that has an overall length of 43.4mm, a width of 16.0mm and a height of 13.3mm. The coil is made from a rectangular porcelain coil former to which a single-layer winding is applied. The inner and outer windings are wire-wound on opposite orizonals, and the two windings are connected in series for use with DC and medium-frequency alternations. The 160R-820KS has a total inductance value of 0.1H to 820H with an accuracy of ± 20%. The inductance can be various depending on the number of turns used, the diameter of the copper wire, the number of copper wires used, and the configuration of the winding.

When a voltage is applied across the terminals of a 160R-820KS fixed inductor, an opposing current is generated due to the inductance of the coil. This opposition to the current flow induces a back force that attempts to reduce the current and voltage. As such, the current that passes through the coil is limited, and the voltage is protected from overvoltage surges and spikes. Additionally, the 160R-820KS can act as a filter by blocking frequencies below the self-resonant frequency of the inductor, thus providing pass-band filtering.

Conclusion

The 160R-820KS fixed inductor is a compact and cost-effective device for applications involving electronic components. It is used in power supplies, mobile phones, automotive electronics, and industrial equipment, and offers excellent efficiency and power density. Its working principle is based on the inductance of the coil, which creates a back force to limit the current and protect the voltage from overvoltage. The 160R-820KS is ideal for applications that need a high current density and small form factor due to its low DC resistance and high performance.
