High performance disk varistors cut in diameter
TDK has launched smaller versions of its metal oxide disk varistors for power supplies
The EPCOS Compact S14 AdvanceD-MP series are smaller with the same performance as comparable S14 AdvanceD-MP types.
The disk diameters of these 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 with a maximum surge current capability of 6 kA at 8/20 µs.
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. The optimized design of the varisotrs results in an improved derating performance over time. All types have UL, CSA, VDE and IEC approval.
The compact dimensions and outstanding electrical characteristics, the Compact S14 varistors help design engineers reduce the size of their products and are suitable for a wide range of applications. These include switch-mode power supplies, drivers for LED lighting, home appliances and smart meters.
The main applications for the varistors are as primary protection against low-level repetitive surge currents in switch-mode power supplies, drivers for LED lighting, home appliances and smart meters.
