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 ...

This paper dial makes selecting current limiting resistors a snap. [Giorgos Lazaridis] came up with the tool, which he describes in detail in the Worklog tab of his writeup. If you want one of your ...

If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is ...

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 ...

Higher-than-normal operating voltages give steppers better torque at high speeds — but watch that current! • The inductance in a stepper-motor phase winding limits how fast current rises when power is ...

Vishay Intertechnology, Inc. (NYSE: VSH) has introduced a new surface-mount Power Metal Strip® current sense resistor that ...

Offline power supplies that drive loads of 200W and more require inrush-current limiters. Unrestricted inrush currents can reach hundreds of amperes, which may damage the line rectifier, open the fuse ...

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.

Nexperia has introduced its first 5V load switch IC, which operates across 2.5 – 5.5V with 110mA to 2.5A current limiting. The 2 x 2mm NPS4053, as it will be know, is optimised use in portable devices ...

Rather than use a fixed-rail voltage source, it’s more efficient and flexible to utilize a current source so that performance remains consistent while supply rail and coil resistance change. Relays ...
