Quality Inspection for Common Mode Choke Filter - SQ Series High Frequency SQ15 Flat Wire Vertical Common Mode Inductor – Sanhe Detail:

Flat wire benefits: high current, small size, low DC resistance, ideal EMI effect, extremely small distributed capacitance, high insulation strength, can extend the life of the power supply, good high-frequency skin effect, unit current density is higher than round copper wire, adopts Fully automatic machine winding, single-layer winding, no cross and no overlap, good heat dissipation effect, and the temperature is lower than the common mode inductance of the magnetic ring under the same circumstances. Closed magnetic circuit design, small magnetic leakage, good impedance balance, very small leakage inductance, good conduction and radiation effect, product consistency and stable performance, high production efficiency, fixed pin position, easy and convenient plug-in operation, reducing labor costs, and saving time , Good quality and high efficiency.
