Resistors
Metal Element Current Sense Resistor
ULR Series
Robust metal strip able to withstand high
temperature and high current.
Low TCR and Inductance
Resistance Range from 0.1mΩ to 10mΩ
Includes anti-sulphur types
AEC-Q200
Higher wattage devices feature PCB clearance gap to
maximize thermal performance
All parts are Pb-free and comply with EU Directive 2011/65/EU amended by (EU) 2015/863 (RoHS3)

conservative design model. The ULR is a solid metal
03.14
alloy construction that can withstand significantly greater
operating temperatures than the conservative model
permits. The protective coating will operate up to
260°C and the alloy can withstand in excess of 350°C.
Therefore, the system thermal design will be a more
signifi cant design parameter due to the heat limitations of
the solder joint.
