Bourns CRK2725 Current Sense Resistors
Bourns CRK2725 Current Sense Resistors are metal strip and wide-terminal current sense resistors designed for accurate current measurement in high-power electronic circuits. These resistors feature ultra-low resistance ranging from 0.2mΩ to 1mΩ, enabling precise current sensing with minimal power loss. The wide-terminal construction improves heat dissipation, while the low inductance (<5nH) and low thermal EMF (<40μV/°C) enhance measurement accuracy. The CRK2725 resistors offer a 5W power rating and operate over -55°C to +170°C temperature range, delivering reliable performance in demanding environments. Typical applications include current sensing, power supplies, stepper motor drives, and input amplifiers.
