Good Quality Common Mode Rf Choke - High Frequency UT Series Power Common Mode Inductor For DVD – Sanhe
Good Quality Common Mode Rf Choke - High Frequency UT Series Power Common Mode Inductor For DVD – Sanhe Detail:
Introduction
It is a UT type common mode inductor, which is mainly used for the voltage input end of DVD power supply. It can eliminate common mode interference and optimize EMC parameters. With a closed-type iron core of high permeability, LCL-20-068 performs well in high-frequency impedance and is usually suitable for occasions where the working current is not very large due to its limited winding space.

Features
1. UT20 structure and double-slot roller BOBBIN
2. Ferrite core of high permeability
3. Two windings are wound symmetrically after the magnetic core is pre-installed
4. Wound by special automatic winding equipment
Advantages
1. Roller BOBBIN structure is suitable for automatic equipment winding, which greatly improves the production efficiency
2. With closed high-conductivity core, the inductance is more stable than non-closed structures such as UU type
3. Compact structure, consistent in size, and easy to assemble
4. Perform well in impedance
