Product Description

Open Air Sense Resistor, Metal Element, Low resistance and inductance, 1% tolerance

 

Open Air Metal Alloy Resistors are designed for sampling current with a very low resistance value from 0.005Ω to 0.1Ω and a very low inductive, offer a high current, flameproof alternative to conventional axial devices and flat chips for current-sense circuits where PC board space is at a premium. The open air resistor's footprint is reduced by extending the height of the device above the board, thus keeping the resistor element's "hot spot" safely off the PC board and providing for increased air circulation under it, which in turn provides increased heat dissipation and cooler operation.

 

Features:

  1. Low inductance.
  2. Radial leads, low resistance value 0.005Ω ~ 0.1Ω.
  3. High stability open-air style. Precision alloys resistive element.
  4. Pb-free and RoHS compliant.
  5. Standard tolerance ±1%, ±2%, ±5%
  6. Open air design and all welded construction

Applications:

 

  1. Inverter and Switching Power Supplies.
  2. CPU Drive Control, Power Tool Motor controls.
  3. Residual Battery Power Detection, Current Sensing.
  4. Automotive, Feedback System, Power Supply Shunt, Current Detective.
