VISHAY – New WSK1206…18 Power Metal Strip® Resistor Features Power to 0.5 W and Kelvin 4-Terminal Connection for Increased Measurement Accuracy and Reduced TCR
The News:
Vishay Intertechnology announces a new surface-mount Power Metal Strip current sense resistor in the compact 1206 case size that combines an extended power rating to 0.5 W with a Kelvin 4-terminal connection that reduces TCR and enables tight tolerances down to 0.1 % for increased measurement accuracy. To minimize excess power dissipation, the Vishay Dale WSK1206…18 High Power offers low resistance values down to 0.01 Ω.
- Offers twice the power of standard resistors in the 1206 footprint
- Saves board space and reduces costs by allowing designers to utilize fewer and smaller components
- Reduces system errors while eliminating the need for system calibration during manufacturing or in the field
- Further reduces costs and improves end product performance
- Advanced construction incorporates a solid metal nickel-chrome or manganese-copper resistive element with low TCR (< 20 ppm/°C)
- Proprietary processing technique produces extremely low resistance values
Product Benefits:
- Compact 1206 case size
- High 0.5 W power rating
- Kelvin 4-terminal connection
- TCR down to 35 ppm
- Tight tolerances down to 0.1 %
- Low resistance values down to 0.01 Ω
