Susumu — World’s Smallest Low Noise Current Sensing Resistor


In high frequency electronics, unwanted noise added by the components themselves can become a significant issue. In order to address this, Susumu offers longer side terminal low resistance chip current sensing resistors.

Their equivalent series inductance is so small that the signal integrity is preserved without adding extra noise. Susumu’s current sensors are also known to be the best in market in heat distribution and heat dissipation.
