The 13FR040E is a 3-watt, axial leaded wire element resistor from the 10 Series, specifically designed for current sensing applications. It provides a fixed resistance of 0.040 Ω with a standard tolerance of ±1% and features low inductance. This RoHS-compliant component is encapsulated in a silicone molding compound and operates across a wide temperature range of -55°C to 275°C. With a low thermal EMF of less than ±2µV/°C and a dielectric withstanding voltage of 1000 VRMS, it is ideal for circuits requiring precise and stable current measurement.
