Current-Sensing Resistors

Littelfuse's resistors provide control and overcurrent protection in an SMD form factor

Image of Littelfuse's Current-Sensing ResistorsLittelfuse's current-sensing resistors provide a cost-effective solution for measuring current in a circuit.

The measured current offers control and overcurrent protection.

Increasingly, applications require current sensing for monitoring and controls.

Features
  • Cost-effective
  • The same part works in AC and DC applications
  • No additional equipment is required
  • High precision and stability
  • Low temperature coefficient of resistance
  • SMD form factor
