EPCOS introduced its LS41 and LS42 Series of compact varistors with high surge current capability for surge voltage protection in industrial and consumer electronics. The surge current capability of the LS41 is increased by 25 percent, and it is now 50 kA at a pulse form of 8/20 µs. These types are designed for rated voltages of 130V AC to 460V AC. The surge current capability of the LS42 is increased by 62 percent to 65 kA. This series is designed for rated voltages between 250V AC and 460V AC. Both series carry approvals to UL 1449 and CSA 22.2.
