Bourns CRK Metal Strip Current Sense Resistors
Bourns CRK Metal Strip Current Sense Resistors feature a robust metal strip resistive element that provides a Temperature Coefficient of Resistance (TCR) as low as 50ppm/°C and a broad operating temperature range of up to 170°C. Bourns CRK is available in 0612 (1632 Metric) and 0815 (2038 Metric) sizes with a 1W power rating. The wide terminal shape of CRK Metal Strip Current Sense Resistors helps provide improved heat dissipation and higher reliability due to larger terminations and solder joint surfaces. The metal resistive element of these current sense resistors results in low inductance, low noise, and excellent reliability. CRK is available with low resistance values (down to 1mΩ) and is ideal for current sensing in consumer and telecommunication electronics and industrial automation applications.Features
