• TDK Corporation’s Open Mode chip varistor protects against transient surge voltages and can handle excessive bending stress
• The component is ideal for battery connected automotive applications

TDK Corporation has introduced a new range of Open Mode chip varistors that offer reliable protection against transient surge voltages. Even under excessive bending stress, short-circuits are prevented, which is particularly important for unswitched battery terminals. This makes the component ideal for electronic automotive assemblies that are directly connected to the battery. 

The new three types of the B725*0G1140S862 series surge protection components have:

• Operating voltage of 14 VRMS or a maximum direct voltage of 16 VDC
• Surge current capability of 120 A, 200 A and 400 A, with each 8/20 µs
• Wide temperature range operability of -55 degrees Celsius to +150 degrees Celsius.
