Fixed Inductors

Fixed inductors are common components used in both analog and digital electric circuits. They are mostly used for inductive coupling, radio frequency (RF) matching, filter networks, snubber circuits, and many other uses. The LK1005R47M-TV is an example of a fixed inductor and is designed for applications with low-profile and low DCR.

This fixed inductor has a flat self-shielded construction with 1005 size. It is wrapped with an epoxy-sealed polyester tape to protect the coils from dirt and moisture. Moreover, the LK1005R47M-TV is RoHS compliant and has superior electrical conductivity. It has a resistance of 47mOhms, inductance tolerance of 20%, inductance range of 10-1000nH, and an operating temperature range of –40 to +125°C.

LK1005R47M-TV Application Field

The LK1005R47M-TV is primarily used in low profile ciruits, as its small size offers a larger capacitance without having to increase the size of the PCB. This fixed inductor is ideal for applications that require low DCR characteristics, such as power supplies, motor control, high-power medical equipment, telecom devices, automotive electronics, and more. The LK1005R47M-TV can also be used for high current input and output filters, signal coupling, and impedance matching.

Working Principle

The working principle of fixed inductors is fairly simple. A fixed inductor consists of a core material, typically iron or ferrite, which is wrapped with a coil of wire. When a current is passed through the wire, a magnetic field is created around the core and induces a voltage in the coil. This voltage is proportional to the amount of current flowing through the coil. The greater the current, the greater the voltage induced in the coil. This induced voltage can then be used to achieve the desired output.

The LK1005R47M-TV was designed to provide excellent performance in high-power applications. Its low DCR characteristics make it ideal for circuits with stringent power efficiency requirements, and its low-profile construction allows for more efficient board designs. This makes the LK1005R47M-TV a great choice for a variety of applications.
