Description

The WSL2512-0.007-1%-B43 is a power metal strip resistor from Vishay Dale. This resistor is designed for high-power current sensing applications, offering extremely low resistance and excellent long-term stability. The 'WSL' series is known for its ability to handle high currents and provide accurate current measurements in demanding environments.

Applications:

  • Current Sensing in Power Supplies
  • Automotive Applications (e.g., Battery Management Systems, Electric Vehicle Charging)
  • Motor Control Systems
  • Industrial Control and Automation
  • High Current Load Resistors

Features:

  • Very Low Resistance Value (0.007 Ohms)
  • High Power Rating (Consult Datasheet for Specific Value)
  • Low Temperature Coefficient of Resistance (TCR)
  • 1% Tolerance
  • All-Welded Construction
  • 2512 Package Size

Benefits:

  • Precise Current Measurement: The extremely low resistance and tight tolerance enable accurate current sensing.
  • Reliable Performance: The all-welded construction provides excellent long-term stability and resistance to environmental stresses.
  • Efficient Power Handling: The high power rating allows the resistor to handle significant current loads with minimal power dissipation.
  • Compact Design: The 2512 package offers a good balance between power handling and size.
  • Stable Performance: The low TCR ensures minimal resistance change over a wide temperature range.

Additional Details:

The WSL2512-0.007-1%-B43 resistor is designed for surface mount applications and requires proper soldering techniques to ensure reliable connections and optimal thermal performance. The device's all-welded construction enhances its robustness and ability to withstand harsh environmental conditions. The low temperature coefficient of resistance (TCR) ensures minimal resistance drift over a wide operating temperature range, which is critical for accurate current sensing. The 1% tolerance ensures the resistance value is within a tight range, improving the accuracy of current measurements. Careful attention should be paid to the PCB layout to maximize heat dissipation and ensure the resistor operates within its specified temperature limits. Consult the datasheet for detailed specifications, including the exact power rating, TCR value, and recommended soldering profile. The material composition and lead-free construction contribute to environmental compliance. It is crucial to consider the derating curve provided in the datasheet, as the power rating is dependent on the ambient temperature and PCB layout. The resistor's small size and high power capability make it an ideal choice for space-constrained applications requiring accurate current sensing.
