POWER METAL STRIP® RESISTORS
WSL1020
Resistors - Wide Side Terminal Construction
Power Metal Strip® Resistors, Wide Terminal,
Low Value (0.003 Ω to 0.006 Ω), Surface-Mount
KEY BENEFITS
• Wide side terminal construction yields high power-to-footprint size ratio (2 W) in
1020 package
• Very low resistance values (0.003 Ω to 0.006 Ω)
APPLICATIONS
Automotive:
Industrial:
• Electronic controls (engine controls,
climate controls, anti-lock brakes, etc.)
• Brushless DC motor controls (electronic
power steering, electric – water pump / oil
pump / air-conditioning, etc.)
• Electric and hybrid controls (battery
management)
Computer:
• Oil / gas well drilling (down hole test /
measurement equipment)
• Air-conditioning / heat pump (inverter
control)
Consumer:
• Air-conditioning / heat pump (inverter
control)
