Fixed Inductors

Fixed inductors (or deposition inductors) are basic electrical components that appear in virtually all electronic circuitry from simple capacitors and resistors to complex integrated circuits. Despite their being named “fixed” inductors, this does not mean they cannot be adjusted or tuned in operation. They are also known as fixed deposits, blocking inductors, chokes, or current chargers.

An example of a fixed inductor is the LK1005R27M-TV. This particular component is an axial wound, air-cored inductor, which is a folded inductor encapsulated in a convenient, shielded package. The inner core is made of ceramic powder, and the outer body is wound with copper coils to provide shielding. It includes a special wire guide feature on both ends of the package enabling easy wire routing and minimal wire clutter, and its outer wall allows for easy mounting and stacking.

Application Field

The LK1005R27M-TV is often used in multi-layer printed circuit boards (PCB). It is designed to meet environmental and electrical performance requirements in VHF/UHF or mobile phone applications, such as communication receivers, base stations, and touchscreens. It is also suitable for data and communication applications that require high EMI shielding performance.

The LK1005R27M-TV is typically used in circuits to filter signals or to control AC line voltage inputs. It can also be used in filter applications to control ambient noise, in power supplies to control ripple, and in Buck or Boost DC-DC converters for noise attenuation. In mobile phones, the LK1005R27M-TV can be used to ensure that mobile phone signals are transmitted and received over a wide area.

Working Principle

Fixed inductors work by restricting the flow of electricity through them, as the voltage increases, the current decreases. This is because an inductor is essentially a coil or loop of wire or metal which creates a magnetic field when current flows through it. When a voltage is applied across the inductor, it acts as a controlling element in the circuit, restricting the current flow and producing resistance. The resistance created is proportional to the amount of voltage applied, and thus the current is regulated and can be accurately controlled.

Fixed inductors are designed to convert alternating current (AC) to direct current (DC) and vice versa. By varying the resistance, the inductor is able to function as a filter, controlling the flow of AC currents and DC voltages. The frequency of the alternating current is determined by the size of the inductor, as the size of the inductor affects the impedance it presents. This allows the inductor to work at optimum frequencies, thereby making it suitable for radio frequency applications.

The LK1005R27M-TV is designed to provide high attenuation at high frequencies with low insertion loss. The magnetic core material is designed to provide high inductance values, while the outer package offers excellent shielding from external electromagnetic fields. The core material is also designed to provide high temperature stability and improved heat dissipation.

The LK1005R27M-TV is suitable for applications where space is limited, due to its small size and high temperature stability. It can also be stacked together to increase its inductance value, making it suitable for applications that require more complex circuits.

In conclusion, the LK1005R27M-TV is a great option for a wide range of applications. It is easy to install and maintain, provides excellent performance, and is available in a range of sizes and packages making it suitable for a variety of applications.
