Bourns SC2 Surface-Mount Wirewound Resistors
Bourns SC2 Surface-Mount Wirewound Resistors are high-precision, four-terminal resistors designed for demanding current sensing and power applications. These resistors offer resistances from 0.005Ω to 1kΩ, tolerances up to ±0.005%, and low temperature coefficients as tight as ±5PPM/°C, ensuring excellent accuracy and stability. Constructed for robust performance, SC2 resistors support currents up to 25A and feature strong surge-handling capability and reliable operation across a broad temperature range. Bourns SC2 Surface-Mount Wirewound Resistors are suitable for DC fast chargers, circuit breakers, industrial motor drives, battery formation, and pulse power systems.
