New 6 W WSLF2512 Power Metal Strip® Resistor Saves Space While Increasing Accuracy and Efficiency
The News:
Vishay Intertechnology announces a new surface-mount Power Metal Strip current sense resistor that combines a high power rating up to 6 W, TCR down to ± 70 ppm/°, and extremely low resistance values down to 0.0003 Ω in the 2512 case size.
• Power density of 192 W/in^2 allows designers to save board space in high-power circuits by utilizing the smallest resistor possible
• Low TCR provides stable and accurate current measurement across a wide temperature range
• Low resistance values minimize power losses and improve end product efficiency
• Advanced construction incorporates a solid metal nickel-chrome, manganese-copper, or manganese-copper-tin alloy resistive element with low TCR (< 20 ppm/°C)
• Proprietary processing technique produces extremely low resistance values
Product Benefits:
• High power rating up to 6 W
• 2512 case size
• TCR down to ± 70 ppm/°
• Low resistance values down to 0.0003 Ω
• Tolerances down to ± 1.0 %
• Low thermal EMF (< 3 μV/°C)
• Very low inductance (< 2 nH)
• Temperature range from -65 °C to +170 °C
• RoHS-compliant, halogen-free, and Vishay Green
Market Applications:
• Current sensing, voltage division, and pulse applications
• Power management for automotive electronic controls such as engine, transmission, anti-lock brakes, audio, and climate controls
• Inverter controls for down-hole test and measurement equipment and HVAC systems
• VRMs for servers
The Key Specifications:
• Power rating at 70 °C: 4 W to 6 W
• Resistance range: 0.0003 Ω to 0.003 Ω
• Tolerances: ± 1.0 % and ± 5.0 %
• TCR: 70 ppm (0.002 Ω and 0.003 Ω), 170 ppm (0.001 Ω), and 200 ppm (0.0003 Ω and 0.0005 Ω)
• Temperature range: -65 °C to +170 °C
Availability:
Samples of the WSLF2512 are available now. Production quantities will be available in November 2016, with a lead time of six to eight weeks for larger orders.
