As the increased demands for precision and stability, Microhm has expanded its thin-film chip resistors NAP Series into three sectors, Standard, High-Precision, and High-Power. The series benefits from an impervious internal passivation layer applied in addition to the normal protective coating. When constructing the NAP Chip Series, a Ni/Cr thin-film material is selectively deposited on an alumina substrate, together with Ni and Sn metallic contacts at each end layer plating. The NAP chips are heat treated to give the requir...

Precision shunts are very precise resistors placed on a circuit in order to measure the current flowing through that circuit. MMS8420 will handle a full-scale current of 600 amps with resistance 0.1m, power at 36 watts. The shunt does this by providing a very small voltage drop across its resistance proportional to the current flowing through the shunt. This can be clarified using Ohms Law, which states that the voltage will be equal to the current multiplied by the resistance (E=IR). Shunts are typically rated according to ...
