New Current Sensing Thick Film Resistors – Increased Power Ratings

KOA’s UR73V-series automotive approved low ohm resistors are designed for current sense applications in demanding environments. The special facedown construction of the VD-version makes lower resistance values with a low T.C.R. possible.

The facedown construction means that the total T.C.R. is minimized due to the shorter current path in the electrodes and solder fillet. The low T.C.R of new UR73V-series and its wide operating temperature range of -55 °C to +155 °C make it ideal for applications such as automotive or high reliability DC-DC converters.

Features:

  • Resistance range: 10 mΩ ~ 100 mΩ (±1 % tolerance)
  • High power rating
  • Lower cost alternative to metal plate parts
  • Standard and face down type available
  • Improved high temperature reliability
  • Operating temperature range: -55 °C ~ +155 °C
  • AEC-Q200 qualified
  • Lab Kits are available

Application Examples:

  • Automotive, including 'under the hood' applications such as ECUs
  • Power supplies
  • DC-DC converters
  • Motor controls
  • Industrial automation
  • Meter
  • LED Lighting
