The WSL-2010 0.015 1% R86 is a power metal strip resistor manufactured by Vishay. This component is specifically designed for current sensing in high-power applications where precision and stability are crucial. The resistor has a very low resistance of 0.015 ohms (15 milliohms) and a tight tolerance of 1%.

Applications:

• Current sensing in high-current power supplies.
• Battery management systems.
• Motor control circuits.
• Inverters and converters.
• Automotive electronics.

Features:

• Power Metal Strip construction.
• Low resistance value: 0.015 ohms (15 mΩ).
• Tight tolerance: 1%.
• High power rating (consult datasheet for specific value).
• Low Temperature Coefficient of Resistance (TCR).
• 2010 surface mount package.
• RoHS compliant.

Benefits:

• High-accuracy current measurements.
• Minimal impact on the circuit's performance due to its very low resistance.

Additional Details:

The 'R86' suffix likely indicates a specific manufacturing or internal control code. The 2010 package defines the physical dimensions as 0.20 inches long by 0.10 inches wide. The specific power rating depends on the datasheet. Thermal management techniques might be necessary for high power dissipation. It is important to refer to the official Vishay datasheet for detailed specifications, including derating curves and TCR values.
