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 ...

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 ...

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 ...

What analog designer hasn't had to derive a nonstandard resistor value by using series/parallel combinations of standard resistor values? In efforts to avoid a production trimpot tweak, we can use 0.1 ...

When using a spreadsheet to calculate circuit values, determining “standard” component values to be used in subsequent calculations can produce more accurate results. This approach will also result in ...

IntroductionIn a circuit that lights up an LED, it is standard to connect a resistor in series with the LED. So, if the power supply voltage is 10 V and the resistor is 1 kΩ, how many mA of current ...

I once worked with an engineer that often checked his resistors with a multimeter before use. I just assumed that he was just being careful (certainly more careful than I…). Then one day, he asked me ...

Resistors are electrical components that oppose the flow of either direct or alternating current. They can be used to protect, operate, or control circuits. In combination with other components, ...
