511-6F

Fixed Inductors

Fixed inductors, also known as chokes, coils, or reactors, are passive two-terminal components that store energy in an electromagnetic field. They have the ability to limit current flow and can act as filters that block certain frequencies. Fixed inductors are commonly used in power electronic and radio frequency applications. This article will discuss the application field and working principle of the 511-6F fixed inductor.

Overview and Definition

The 511-6F series is a range of fixed inductors from Murata Electronics. It is a cylindrical, ferrite-core device with a rate voltage of 125 V. Depending on the model, its operating temperature range is -40°C to 105°C. The 511-6F series can be used for wave form shaping and general filtering of digital signals, as well as for impedance matching.

Application field

The 511-6F series has a wide range of applications due to its low insertion loss and high self-resonant frequency. It can be used in power supplies, for switching circuits, for noise suppression in motor control systems, and for VHF circuits in automotive and industrial electronics. It is also commonly used in radio circuits, for frequency shaping and general power filtering, and in television signals and video circuits.

Working principle

Fixed inductors work by storing energy in an electromagnetic field. When current flows through the coil, it creates a magnetic field in the core. This field stores energy, which is released when the current flow is interrupted. The amount of energy stored depends on the inductance of the coil and can be calculated by multiplying the current flowing through the coil by its inductance value. The self-resonant frequency of the 511-6F series is typically between 1 MHz and 100 MHz, depending on the model.

Summary

The 511-6F series of fixed inductors are versatile components that can be used in a variety of applications, from power supplies and motor control systems, to radio and television signal circuits. Their low insertion loss and high self-resonant frequency make them ideal for wave form shaping and general filtering of digital signals. They work by storing energy in an electromagnetic field, which is released when the current flow is halted. The amount of energy stored depends on the inductance of the coil and can be calculated by multiplying the current flowing through the coil by its inductance value.
