Introduction
Choke coil, also known as choke coil, is divided into high-frequency choke coil and low-frequency choke coil. The high-frequency choke coil is inserted into the core coil, which is mainly used to prevent the passage of high-frequency signals in the circuit; the low-frequency choke coil is to insert silicon steel sheets and other core materials in the air core coil to prevent the passage of low-frequency signals in the circuit. Low-frequency choke coils are often used together with capacitors to form a power supply filter network in electronic devices.

Product details
Scope of application: chokes are widely used in various electronic circuits, such as frequency converters, inverters, DC-DC converters, filters, etc. In these circuits, the role of chokes is to limit the rate of change of current, protect electrical equipment and circuit components, eliminate electromagnetic interference, and improve circuit efficiency.

Product features/equipment features
The common mode choke adopts ferrite core, double wire winding, has high common-mode noise suppression and low differential mode noise signal suppression ability, difficult to deform in high-speed signal, small size, easy to use, with good balance, easy to use, high quality and other advantages. And the impedance of the working frequency band is small, the impedance of the interference frequency is large, the inductance value is stable, the thermal stability is good, and a variety of structural forms and impedance characteristics are available.
