Thunder Precision Resistor Co., Ltd. has been looking for high quality metal foil materials to making ultra precision metal foil resistors as ultra precision metal foil resistor networks.
Metal foil resistors is one kind of solid body resistors that is of ultra high stability and reliability compared to traditional metal film resistors and is very expensive or say the most expensive resistors. Vishay is the largest manufacturer of metal foil resistors in the world and Thunder Precision Resistors will work hard to make the metal foil resistors with same quality as Vishay's to serve our customer better.
By the way, the stability of ultra precision metal film resistors and ultra precision resistor networks made by Thunder Precision Resistors is less than 50ppm/year that is almost the same as Vishay's metal foil resistors.
