The simple addition of a transistor and resistor to the open-circuit drive overcomes this dilemma by limiting current through the drive transistor. Transistor Q2 provides the open-collector drive ...

In the upcoming Open Circuits from No Starch Press, authors Windell Oskay, co-founder of Evil Mad Scientist Laboratories, ... In a spread about thick film resistor arrays, ...

Bourns’ CRK1225 automotive-grade current sense resistor offers a higher power rating and wider resistance range.

In production, this may be replaced with a zero Ohm resistor. The open circuit protection circuit shown utilizes R9, causing it to serve an additional function, in conjunction with Zener diode D2. In ...

At DC, the bottom circuit will look like a 1 kΩ resistor along with whatever resistance the inductor’s wire presents ... We can imagine the inputs of the op amp are open circuits.
