High-frequency transformer coil

New-type designed transformers are primarily used as high-frequency switching power transformers in high-frequency switch-mode power supplies; they are also employed in high-frequency inverter power supplies and high-frequency welding machines as high-frequency inverter transformers. Depending on the operating frequency, they can be further classified into several categories: 10 kHz–50 kHz, 50 kHz–100 kHz, 100 kHz–500 kHz, 500 kHz–1 MHz, and above 1 MHz.

Filter inductor for power-factor-boosting circuits

The newly designed filter inductor is suitable for energy-storage and filtering applications in switch-mode power supplies due to its high magnetic flux density (Bₛ value) and low-loss characteristics. Compared with iron-powder cores and ferrite cores of the same volume and permeability, it offers higher energy-storage capability, making it more widely used in AC chokes, output inductors, rotary transformers, pulse transformers, and power-factor-correction circuits.

High-Quality Electronic Components – CMC Coils

The new common-mode choke features a ferrite core and a dual-wire winding, delivering outstanding common-mode noise suppression while providing relatively low suppression of differential-mode noise signals. It remains stable under high-speed signaling conditions and exhibits low impedance at operating frequencies, high impedance at interference frequencies, and a compact footprint.
