Founded in 1977, Yageo Corporation is a premier global provider of passive component solutions. Through strategic acquisitions of industry leaders such as Pulse Electronics, BrightKing, and KEMET, the company has built a comprehensive product portfolio and established a commanding presence across the electronics industry, particularly in capacitors, resistors, and circuit protection technologies. Our extensive range of Yageo components is heavily focused on their advanced circuit protection solutions. We carry a comprehensive selection of transient voltage suppression (TVS) devices, featuring hundreds of TVS diodes and varistors engineered to safeguard sensitive electronics from destructive voltage transients. This core offering is complemented by a robust lineup of gas discharge tubes (GDTs) designed for reliable overvoltage protection in demanding environments. Beyond voltage suppression, we supply a variety of Yageo's specialized thermistor products, including resettable fuses, inrush current limiting (ICL) NTC thermistors, and precision temperature sensing components. Rounding out our selection are high-performance Yageo RF and single-band chip antennas, providing reliable, space-efficient connectivity for modern wireless applications.
