  • Characteristics of cores of different shapes

    Characteristics of cores of different shapes

    Common core shapes include can, RM, E, E-type, PQ, EP, ring, etc. Different core shapes have different characteristics:   1. Can The skeleton and winding are almost completely wrapped by the core, so the EMI shielding effect is very good; the can design makes it more expensive than the cor...

  • Causes of high frequency transformer temperature rise and how to solve it

    Causes of high frequency transformer temperature rise and how to solve it

    When the temperature of each part of the high-frequency transformer exceeds its allowable range for a long time, the insulation of the high-frequency transformer will be easily damaged, which can easily cause high-frequency transformer failure or accident. So what are the reasons for the high-fre...
