Introduction

Common Mode Chokes, also known as CM chokes, are widely used in the design and manufacture of electronic equipment and systems. In the case of UF-1717H-132Y07-01, they can be used to filter out interference signals in paired wires or cables. This article will focus on the application field and working principle of UF-1717H-132Y07-01 Common Mode Chokes.

Application field

Common Mode Chokes, like the UF-1717H-132Y07-01 model, are available in a variety of sizes. The size of the common mode choke and its associated parameters, such as inductance, depend on the application in which the choke is to be used. Generally speaking, UF-1717H-132Y07-01 Common Mode Chokes are best suited for DC-DC converter applications, where excellent linearity and low output ripple are required. Common Mode Chokes are also used in power supply designs, LCD display applications, motor controller systems, power line filter designs, and automotive applications.

Working Principle

Common Mode Chokes are essentially coils wound around a ferrite core. They are designed to create inductance in the signal wires or cables that are connected to them. This inductance is used to reduce or suppress common mode noise and other forms of interference.The principle behind the common mode choke is that current flows in an Anti-Inductive or Reactance Direction, which is opposite to the lines of flux created by the inductance. As a result, these lines of flux absorb noises that are present in the signal wires or cables, thereby reducing their effect on the connected electronic devices.In addition, the common mode choke also provides noise isolation to the connected devices. This is done by creating an impedance that reduces the current through the signal wires or cables, thus reducing the amount of noise generated in the connected devices.In sum, UF-1717H-132Y07-01 Common Mode Chokes are used in a variety of applications, and they work by creating an inductance in the signal wires or cables that is used to reduce or suppress common mode noise and other forms of interference. In addition, it also provides noise isolation to the connected devices.
