When there is a voltage difference between adjacent windings, the plate effect will form parasitic capacitance. Especially in high-frequency switching, repeated charging and discharging will aggravate energy loss.
The capacitor pen coil, hidden inside the pen tip, is the core component for electromagnetic induction or resonant communication, directly determining touch accuracy, response speed, and lifespan.
With the increasing trend towards thinner, smarter, and more energy-efficient modern electronic devices, the high-frequency transformer—a core component of power systems—is playing an increasingly crucial role.
Common mode inductors, through their unique structural design and impedance matching mechanism, effectively suppress current imbalance in three-phase systems.
From a process design perspective, the presence of distributed capacitance places stringent requirements on the high-frequency transformer winding process.
At high frequencies, core losses and winding copper losses can cause a significant temperature rise in the inductor. The permeability of the core material decreases with increasing temperature, which in turn reduces inductance and suppression capability.
