FAQ
Q: What affects the inductance of toroidal common‑mode choke?
A: Inductance depends on core material, core dimension, winding turns. Symmetry of dual‑wire winding also impacts electrical performance.
Q: What is toroidal common‑mode choke used for?
A: Toroidal common‑mode choke is mainly installed at AC input of switching power supplies to suppress common‑mode EMI noise. Widely used in adapters, industrial power supplies, chargers, energy‑storage and household appliances.
Q: What is its main function?
A: The core function is filtering and anti-interference. It is usually installed at the power input end, which can prevent the noise generated by the equipment from being transmitted back to the power grid, and also prevent external interference from affecting the equipment. Because it is a closed ring structure, the magnetic leakage is very small, and its filtering effect is better than that of ordinary inductors.
Q: How to choose the appropriate model?
A:When selecting, mainly consider two parameters: inductance and rated current. The product in the picture has many specifications to choose from, such as 220uH, 3A, or 10MH, 20MH, 30MH, as well as the high-power version of 6mH, 5A. When choosing, it should be based on your working frequency and the maximum current that needs to be passed.

Q:How to determine its size?
A:The size is usually marked as: outer diameter x inner diameter x height, for example, 9x5x3 or 10x6x5 mm (mm). If space is limited, it needs to be selected according to the reserved position on the PCB board. Small transformers or devices with high current usually use a 4-pin package, which is convenient for fixing on the circuit board.
