"STARPAS" is a shielding material for magnetic fields and electromagnetic waves made from magnetic metal (permalloy). Thicker materials can create areas that do not contribute to shielding as the frequency increases. Therefore, by making the material thinner and eliminating those areas, it can be effectively utilized even in alternating current, contributing to the miniaturization and lightweighting of shielding devices. It is suitable for shielding materials such as CMOS image sensors, power and control ICs, and flexible cables. Please use it as a noise countermeasure sheet in magnetic field immunity tests such as ISO 11452-8, MIL-STD-461 RS101, and IEC61000. 【Features】 ■ Made from magnetic metal (permalloy) ■ Suppresses eddy currents in alternating current and maintains high permeability at high frequencies ■ Diverse material properties ■ Applicability to shielding ■ Processable *For more details, please refer to the PDF document or feel free to contact us.
