Metal-oxide disk varistors come in compact packages

November 14, 2019 By Aimee Kalnoskas

Compact S14TDK has announced the EPCOS Compact S14 AdvanceD-MP series of metal oxide disk varistors that feature smaller dimensions with the same excellent performance as comparable S14 AdvanceD-MP types. The disk diameters of the new B72214P2 varistors range from 13 mm to 14 mm, a reduction of approximately 3 mm. Like their current S14 counterparts, these components offer a maximum surge current capability of 6 kA at 8/20 µs according to IEC 62368-1. Like their current S14 counterparts, these components offer a maximum surge current capability of 6 kA at 8/20 µs according to IEC 62368-1.

The Compact S14 series covers a wide operating voltage range from 130 to 460 VRMS. The multiple pulse varistors are designed to be used in power supplies as the primary protection against low-level repetitive surge currents. Their optimized design results in an improved derating performance over time. All types have UL, CSA, VDE and IEC approval.

Applications include switch-mode power supplies, drivers for LED lighting, home appliances and smart meters.
