One of the questions that hobbyists ask over and over is how to select the value of a current limiting resistor for an LED. Usually the seat of the pants response is: “Subtract 2 V from the supply ...

VCC has designed a series of LED sockets that feature a built-in current limiting resistor to provide optimal LED performance. VCC has designed a series of LED sockets that feature a built-in current ...

There are so many applications for power resistors that they cannot be easily tabulated. Discussed here are a few practical, useful applications that you will find interesting. First an image with ...

Question: Could I easily and precisely limit a current to my load? Answer: Yes, there are current limiting ICs available. In some power management applications, precise current limiting is required.

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...

This resistor with bands of red, violet, yellow, and gold has a value of 270,000 ohms (270kΩ) with a tolerance of ±5%. \( \begin{eqnarray*}\text{R}_\text{t ...

This file type includes high resolution graphics and schematics. LED-based lighting is replacing incandescent and gas-discharge lamps in many situations. As practical lighting sources, and considering ...
