Additional Details

The WSL2512R1000FED features a solid metal nickel-chrome or manganese-copper alloy resistive element with low TCR (Temperature Coefficient of Resistance). This ensures minimal resistance change over a wide temperature range. The resistor is available with a tolerance of 1% or 5%. The Power Metal Strip® construction enhances its ability to withstand high surge currents. The operating temperature range is -65°C to +170°C. This surface-mount resistor is ideal for automated assembly processes and is RoHS compliant. The resistor's small size and high power rating make it suitable for applications where board space is limited. The low inductance helps maintain signal integrity in high-frequency circuits.

The resistor's welded construction contributes to its overall robustness and reliability. The Vishay WSL series is known for its superior performance in current sensing applications compared to standard chip resistors. The WSL2512R1000FED provides a cost-effective solution for precise current measurement and control in a variety of electronic systems.
