The role of resistors in South America

The role of resistors in South America
South America’s unique geography means it has a wide diversity of wildlife unique to the continent. The llama, anaconder, anteater, agoiti and chinchilla are just some of the 40% of the world’s plant and animal species native to South America. Here, Stewart Wittering, Marketing Director for South America at resistor manufacturer, Cressall Resistors, explains how the South American geography and climate affects the resistor market.

Alternistor triacs simplify thermal management

Alternistor triacs simplify thermal management
Littelfuse has introduced two series of High Temperature Alternistor Triacs, the latest additions to the company’s thyristors portfolio. With a maximum junction temperature of 150°C, the 16A QJxx16xHx Series and 25A QJxx25xHx Series are designed for use as AC switches, helping circuit designers address overheating challenges in AC power control applications. Their high peak, single cycle AC current pulse ratings allow them to tolerate higher in-rush currents in heater or motor control applications.
