Common Choke

Shinenergy’s common choke is the common mode choke, it could block the high-frequency noise common to two or more data or power lines, at the same time, allowing the desired DC or low-frequency signal to pass.

  • Higher inductance value compared with the differential choke
  • Block or suppress the high frequency signal
  • Keep EMI radiation in a low level
  • CE, UL certificated
Magnetic Core

Nanocrystalline Core has the Higher Efficiency

Shinenergy’s common choke cooperates with the nanocrystalline core, which is 8-10 times more effective than the ferromagnetic and ferrite core. It’s compact and has a higher frequency range of up to 20KHZ. Meanwhile, the EMI suppression function has also been increased when using the nanocrystalline core.

Toroid Style to Provide the Highest Impedance

Toroid-style common chokes are specially designed to provide the highest impedance within the broadest frequency range, in application that requires high DC current bias, toroid-style common chokes are the ideal option. They are most effective in filtering supply and return in-phase signals.

Q1: How to choose a common choke?

A1: There are three main criteria: required impedance, frequency range, and how much differential mode current must handle.

Q2: What kind of the signal that common choke could suppress?

A2: Common chokes could block electromagnetic interference (EMI) and radio frequency current (RFI) signal from a power supply.
