Ralec alloy resistors were founded by Ralec Technology in 1994. Ralec is committed to becoming a professional manufacturer of chip resistors, resistors, and metal plate current sensors. Ralec has three production bases in Kaohsiung, Taiwan, Kunshan, China, and Malaysia. After merging into Qilixin Group in 2017, a new production base was built in Yuanling, Hunan, China in 2018. In addition to focusing on high-quality product manufacturing, we also strengthened research and development of precision products with higher precision and smaller volume. In response to market demand and development trends, we also increased investment in the development of metal plate current detection resistors to provide global customers with highly reliable and innovative products. Our goal is to become a leading professional manufacturer of chip resistors with advanced technology.
