EMI Line Filters for filtering common mode
power line noise (TCUU)
Preview
In recent times there has been a growing need for energy storage inductors for noise filtering in both mains line
filters and DC chokes used in switched-mode power supplies. In mains line filter applications the filtering falls
into two categories: common-mode noise and differential-mode noise.
The line filter arrangement consists of two sections bobbin between the mains supply and the equipment. Note
that the common-mode filter is wound on a single core and the differential mode filter consists of two indiviual
wound cores. The common-mode noise is in relation to ground and is common to both lines. Differential mode
noise is the noise between the two lines. Both types of noise are usually present to varying degrees.
Token line filters TCUU series common mode choke coils are used in a wide range of prevention of radio
frequency interference (RFI) and electromagnetic interference (EMI) from power supply lines and for prevention
of multifunctioning of products such as measuring equipment and system equipment. Features wide range of
selection, high impedance at applicable frequency, and high self-resonant frequency.
The TCUU series is designed to reduce stray capacity between windings by using a single-layer coil and
two sections bobbin construction on high permeability ferrite core, which offer excellent high frequency
characteristics. This series provides excellent noise suppression for high frequency ranges including the FM
band. This filter can also be used as a signal line with excellent withstanding voltage, since the windings are
divided into two sections.
Token is equipped to design and produce custom components to meet many design and reliability demands.
