VISHAY WSLP0805 Current Sense Resistor, 0.005Ω ±1%, 1W, 0805

The VISHAY WSLP08055L000FEA18 is a low-value, surface-mount resistor from the high-performance Power Metal Strip® WSLP_18 Series. Designed for precision applications, it offers an outstanding power-to-footprint ratio, making it ideal for space-constrained, high-power designs.

Constructed with a solid metal nickel-chrome or manganese-copper alloy resistive element, it delivers extremely low resistance values with a low temperature coefficient (TCR). This proprietary processing ensures stable performance and high reliability. The resistor is inherently sulphur-resistant by construction, making it unaffected by high-sulphur environments, a critical feature for long-term stability in harsh conditions.

Key Performance Features

• Excellent Electrical Characteristics: Features very low inductance (0.5nH to 5nH) and an excellent frequency response up to 50MHz.
• Low Thermal EMF: Provides minimal thermal electromotive force, rated at less than 3μV/°C, essential for precision measurement circuits.
• Robust Power Handling: Rated for 1.0W of power at an ambient temperature of 70°C.
• Wide Operating Range: Functions reliably across an extensive temperature range from -65°C to +170°C.

This component is engineered for demanding roles in current sensing, voltage division, and pulse applications where accuracy, stability, and power density are paramount. Its compact 0805 (2012 metric) package houses advanced technology for superior performance in automotive, industrial, and telecommunications systems.
