ULRG12512R010FLFSLT Datasheet, PDF (1/6 Pages) IRC - a TT electronics Company. – Metal Element Current Sense Resistor

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 0.5 mΩ to 20 mΩ
• Power ratings from 1W to 3W in 1206, 2010 and 2512 chip size
• Designed for current sense circuits in power electronic systems
• Higher wattage devices feature PCB clearance gap to maximize thermal
performance
