Because of rising raw material costs, Taiwanese chip resistor manufacturers have begun increasing prices, with the wave spreading from major passive component makers such as Yageo and Walsin to smaller players like Ta-Yi Technology and Ever Ohms. After issuing a price increase notice to customers, Ever Ohms said that long-term competition in the Chinese market had kept chip resistor prices under pressure. However, recent surges in the costs of silver, palladium, ruthenium, tin, and copper have forced several Taiwanese and Chinese passive component suppliers to raise prices.
