This Excel spreadsheet uses conditional formatting to highlight the resistor pairs in a design that can create a particular ratio. The target ratio is entered in cell C3, and the tolerance is entered ...

The CSS/CSSH current-sensing resistors offer values down to 0.25 milliohms in a standard surface-mounted chip package. This resistor series is rated for full-power operation at up to 100°C, and has an ...

A hard drive crash, and some other happenings that aren’t entirely clear to us, led [Devbisme] to put in a parts order. As he wanted to make the most of his shipping costs, he decided to fill out the ...

I have often wondered whether the practice of using a ratio of two resistors to determine a particular output is a fundamental property of electronics or a concerted effort by designers. In either ...

Download this article in PDF format. Determining the resistor values and assuring performance of the circuit associated with a photocoupler (also called an optocoupler or optoisolator) is simple in ...

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 ...
