Potentiometers, or variable resistors, are a standard component that we take for granted. If it says “10k log” on a volume pot, than we fit and forget. But if like [Ben Holmes] you are modelling ...

The newer a piece of farm equipment, the more likely some aspect of it needs to be calibrated, and sometimes re-calibrated, for it to work correctly. In case. you’ve ever wondered, here’s what ...

In many system applications, it becomes necessary to adjust a switched-mode power supply (SMPS) output voltage within narrow limits in order to remove tolerances and drops in the power path, verify ...

A circuit used to control the level of a video signal should have a 3-dB cutoff frequency of greater than 5 MHz for a television application or 100 MHz for a monitor application. CMOS-based digital ...

Designed for operation in harsh environments where long life and reliability are critical, the 6209 Series of aerospace quality potentiometers features materials and epoxies that can operate ...

I have a Volcano 7 variable speed fan on my Duron 1.2Ghz machine. The fan speed is controlled by a temp. sensor between a 'low' and 'high' speed. The problem is, the crossover point for the two speeds ...
