About Marum Consulting, Marum Consulting specializes in high current curve tracers to characterize device behavior under electrical overstress (EOS) and Electrostatic Discharge (ESD) conditions. These curves show how devices behave under Human Body Model (HBM) and IEC 61000-4-2 system level ESD stress as well as IEC 61000-4-5 surge stress conditions. These instruments complement, and in many cases can replace, a much more expensive Transmission Line Pulser (TLP) test system.
