WSK1216L5000FEA Current Sense Resistor | 0.5mΩ/5W | ±1% | 4-Terminal | 1216 Package | Vishay Automotive Grade

The WSK1216L5000FEA is an automotive-grade Power Metal Strip® current sense resistor from Vishay Dale, part of the WSK series. This device features a 4-terminal (Kelvin) design that separates the current path from the sensing point, effectively eliminating contact resistance effects on measurement accuracy and reducing errors caused by copper's temperature coefficient . It features a 1216 package (3.81mm × 3.10mm × 1.9mm), with an ultra-low resistance of 0.5mΩ, power rating of 5W, tolerance of ±1%, temperature coefficient of ±150 ppm/°C, and an operating temperature range of -65°C to +170°C . Its all-welded metal element construction ensures extremely low inductance (0.5nH to 5nH) and low thermal EMF (<3µV/°C), along with anti-sulfur, moisture-resistant, and pulse-withstanding characteristics . The product is AEC-Q200 qualified, making it ideal for automotive electronics, battery management systems, power management, and industrial controls requiring reliable current sensing .
