Technical Specifications
Attribute
Details
Resistance Range
0.5m to 500m
Operating Temperature
Up to 170C
Features
Low thermal EMF version, High power version, Inverse version
Application
Current sensing for power electronics
Marking
Ohmic value (e.g., "R002"=2m, "R010"=10m). Specific markings for LRMAM1206 ("01"=1m), LRMAM0805 ("2"=2m, "010"=10m)
Thermal Performance & Mounting
Temperature rise dependent on mounting conditions. Reference conditions assume 20m copper with thermal vias. Self-heating in current tracks should be negligible or accounted for by derating. Designed for PCB mounting; probed measurements may read higher values.
Reference Pad Dimensions (mm)
2.8 x 1.7 (0612), 0.4 x 1.83 (0805), 0.4 x 2.8 (1206), 1.2 x 4.5 (2010), 1.5 x 5.8 (2512), 5.4 x 3.4 (1225)
Probe Location Tolerances
0.02mm
Processing
Suitable for wave and IR reflow soldering. Recommended reflow profile for Pb-free SAC305 alloy: Pre-heat: 60s-120s at 150C-180C; Soldering: 20s-40s at 230C; Peak: 5s at 255C-260C
