Expanding the S-Line of precision Bulk Metal Foil current sense resistors, the SHLR series current-sense resistors (SHLR 4-2321, SHLR 4-3825, and SHLR 4-3825H) are the industry's first such devices to combine low resistance down to 0.001Ω, TCR to ±2 ppm/K, and high power ratings up to 50W. Offering load stability to 0.1% for up to 2,000 hours, the resistors feature a wide range of power ratings: from 3W in free air to 50W when mounted on a heatsink Resistance values span from 0.001Ω to 0.005Ω with tight tolerances to ±0.1%. Other features include maximum currents to 150A, an inductance, thermal EMF of < 1 μV/K, thermal resistance down to 1.6 K/W, and an operating temperature range of -40°C to +130°C. Offered in anodized aluminum packages, the devices are RoHS-compliant and lead (Pb)-free.
