New WSK1216 Power Metal Strip® Resistor Delivers High Power Density of 260 W/in^2 and Increased Measurement Accuracy
The News:
Vishay Intertechnology announces a new surface-mount Power Metal Strip current sense resistor that provides a high power rating of 3 W in the compact 1216 case size. The Vishay Dale WSK1216 features a Kelvin 4-terminal connection for increased measurement accuracy, while its extremely low resistance of 0.001 Ω minimizes power losses to improve end product efficiency.
• Power density of 260 W/in^2 allows designers to save board space in high-power circuits by utilizing the smallest resistor possible
• 4-terminal connection is less affected by temperature than typical 2-terminal devices, reducing system errors
• Advanced construction incorporates a solid metal manganese-copper alloy resistive element with low TCR (< 20 ppm/°C)
• Proprietary processing technique produces extremely low resistance values
Product Benefits:
• High power rating of 3 W
• Compact 1216 case size
• Kelvin 4-terminal connection
• Low resistance of 0.001 Ω (0.0005 Ω coming Q1 2017)
• Stable resistance tolerances down to 1 %
• Low thermal EMF (< 3 μV/°C)
• Very low inductance down to 0.5 nH
• Temperature range from -65 °C to +170 °C
• Maximum solder temperature up to 350 °C for 30 s
• 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, intelligent parking brakes, audio, and climate controls
• Inverter controls for down-hole test and measurement equipment and HVAC systems
The Key Specifications:
• Power rating: 3.0 W
• Resistance: 0.001 Ω (0.0005 Ω coming Q1 2017)
• Tolerance: ± 1.0 %
• Temperature range: -65 °C to +170 °C
Availability:
Samples and production quantities of the WSK1216 are available now, with a lead time of six to eight weeks for larger orders.
