Total Solution for Better Magnetic Component

These products are used in solar photovoltaic power generation and eco-friendly vehicles to stabilize the noise, thermal shock, vibration, etc. Chang Sung's technology always ensures trust and safety.

Chang Sung's Inductors are produced using the inhouse developed raw powders and magnetic powder cores, which have a lower loss at a high frequency compared to the inductors using silicon steel cores and provide higher temperature stability than the inductors using ferrite cores. The inductors are used as essential components of power converters in air conditioning, solar and eco-friendly vehicle applications.
