ERJ-M1WSF20MU 20 Milliohm Metal Element Current Sense Resistor In 2512

ERJ-M1WSF20MU is a surface-mount current sense resistor specified at 20mΩ with ±1% tolerance and 1W power rating. Construction is a metal element type, with a temperature coefficient of ±100ppm/°C. Operating temperature range is -55°C to 170°C. Package is 2512 (6332 metric) with a 6.40mm x 3.20mm outline and 1.10mm maximum seated height. The device uses 2 terminations and is categorized for current sense applications where low resistance and defined tempco are selection drivers. ERJ-M1WSF20MU is marked obsolete, which can matter for lifecycle control and documentation alignment in sustained builds. Selection typically centers on resistance value, tolerance, tempco, package geometry, and power handling. Request A Quote For ERJ-M1WSF20MU.
