WSHM2818 Power Metal Strip® Resistor
Vishay Dale's WSHM2818 Power Metal Strip offers robust AECQ200 qualified automotive grade performance
Vishay Dale's Power Metal Strip WSHM2818 is an all-metal welded construction that offers robust AECQ200 qualified automotive grade performance. The resistance element consists of a low TCR alloy (< 20 ppm/°C) that is much thicker than the resistance element of a thick film or foil technology that provides superior pulse and overload performance. Additionally, the construction of the WSHM2818 wraps the large copper terminals directly under the resistance element to maximize heat transfer efficiency from the element to the board so that it can maximize the power density of the design as well as reduce the effects of PCR (TCR effects due to applied power).
Features and Benefits
- Low resistance value, down to 0.001 ohm
- High power rating (up to 7 W)
- Tight tolerance available, down to 0.5%
- High pulse capability
- Low TCR, down to 75 ppm
- Low inductance, < 5 nH
- AECQ200 qualified
- Low thermal resistance minimizes effects caused by PCR
Applications
- Battery management
- Automotive electronic controls; oil pump, electronic power steering, air conditioning
- Brushless DC motor control
- Automotive and industrial inverter power supplies
