Stackpole Introduces 0508 Reverse Geometry 1 W Current Sense Chip Resistor

Stackpole’s CSS0508 is a one-watt current sense chip resistor that combines high power in a small package, low resistance values, and low TCR in a robust all-metal technology. In addition, the 0508 long side termination allows the part to run cooler under full rated power than similar size chips because the larger terminations are far more thermally efficient.

Stackpole Adds 1216 and 4026 Sizes of High Current Four Terminal Shunt Resistors

Low resistance values are important for high efficiency current sensing in that lower values mean less wasted power on the current sensing measurement itself. But sensing low resistance values becomes challenging because of lead resistance. Using a four terminal shunt resistor eliminates the detrimental effects of lead resistance on the current sensing measurement operation.

Thermal Noise, Current Noise & Corrosion on Resistors

Posted by Tomáš Zedníček

Noise manifests itself as a spontaneously fluctuating voltage whose instantaneous amplitude is randomly distributed. The instantaneous value is both unpredictable and of minor interest except in certain critical applications. Instead, one measures a time-averaged value. It consists of the root of the mean-square value of voltage transmitted in a particular frequency pass band.

Construction and Types of Wirewound Resistors

Posted by Tomáš Zedníček
On March 6, 2020

As the name indicates wire-wound resistors consist of a resistive wire wound on a bobbin and supplied with a protective coating. Since the resistance wire never can serve as a termination wire because of solderability requirements, it has to be connected to the terminal leads or the like, usually by welding or brazing. The higher the resistance value the thinner the wire that has to be used and thus the greater the risk of open circuits due to deficient weldings, damage from corrosion or from mechanical handling. Below a diameter, Φ, of 0.1 mm (4 mils) the failure rate grows rapidly.
