With surface-mount components quickly becoming the norm, even for homebrew hardware, the resistor color-code can sometimes feel a bit old-hat. However, anybody who has ever tried to identify a random ...

What kinds of applications utilize precision resistor trimming? Obvious applications include setting operational-amplifier gain and offset and voltage regulator output (Fig. 1a and 1b). But there are ...

One of the standard methods used to measure load current is to insert a low-value resistor in the load line and sense the voltage across it, Figure 1, followed by an analog or digital implementation ...

It’s not easy being a current-sense resistor: so much is expected of this basic function of determining current flow by simple measurement of voltage across a known resistance, then applying Ohm’s Law ...

How and why sub-milliohm chips warrant consideration as a separate class of component. Strategies for smart component selection, layout design, inspection and soldering process control. While ...
