Current sense resistor series spans 0201 to 1225 packages with power ratings up to 3 W

June 4, 2025 By Redding Traiger

Sense resistors are commonly used in applications such as low-power electronics, consumer devices, lighting systems, and security or detection equipment for power monitoring and control. These applications often do not require ultra-low resistance values, tight precision tolerances, or low temperature coefficient of resistance (TCR).  Instead, they prioritize flexibility in form factor and affordability. Stackpole’s CSR […]

FAQ on pull-up/pull-down resistors: part 2

September 11, 2024 By Bill Schweber

Even this relatively simple circuit arrangement has subtleties that affect performance. Part 1 explored the role of pull-up and pull-down resistors to ensure that the binary (digital) circuit points are at an unambiguous 1 or 0 level. This part explores basic issues of sourcing, sinking current, and resistor sizing. Sourcing and sinking current Q: What […]
