Yageo Corporation launched two smaller sizes of anti-surge chip resistors: 0402, 0603. By this extension, SR series covers sizes from 0402 to 2512, with ±5%, ±10%, and ±20% tolerances. The resistance range is from 1 Ω to 100 KΩ at an operating temperature range of –55 °C to +155 °C. In the sometime, Yageo also provides high power anti-surge chip resistor, sizes from 0402 to 1206 with 0.125 W to 0.5 W.
Nowadays, electronic devices are becoming smaller and thinner, and the need for surge protection is becoming essential to electronic circuit design. To this end Yageo had developed the SR series anti-surge chip resistors to meet the market demand.
For resistors, an electrical surge is a common cause of failure in circuits. Yageo has optimized the manufacturing process and structure design to enhance power dissipation and anti-surge protection capabilities.
Featuring with excellent anti surge characteristics, the SR series protects electronic devices against short time overload. For example the SR2512 is able to withstand a power surge up to 10,000 W under 10 µs duration.
The SR series features a higher power rating and excellent anti-surge protection characteristics. The typical applications are: power supplies, industrial, alternative energy, lighting, automotive and telecommunications.
