With a 4k1 collector resistor and 16mA drive into the led, the chosen (read ‘cheapest on ebay’) 6N135 is supposed to beat 1.5μs for both turn on and turn off, with typical figures of 90ns and 800ns.

A breakthrough in neuromorphic computing could lower the energy consumption of chips and accelerate progress toward artificial general intelligence (AGI). Researchers from the USC Viterbi School of En ...

Electricity powers everything from your phone to your refrigerator—but have you ever wondered how it’s controlled inside a ...

This video breaks down how resistors work and why they’re one of the most essential components in every electronic device.

Abstract: Diffusion-driven instabilities with pattern formation may occur in a network of identical, regularly-spaced, and resistively-coupled cells if and only if the uncoupled cell is poised on a ...

Bourns’ Riedon precision wirewound resistors offer a wide range of resistance values in multiple packages for demanding ...
