Electrical characteristics

Limits as printed in the datasheet (page.json metadata.characteristics carries them as data).

Parameter Symbol Min Typ Max Unit Conditions Page
Short-time overload resistance change -0.5 0.5 % Run at 5 times rated power for 5 s at room temperature; printed as ±(0.5%+0.0005Ω), the 0.0005 Ω absolute term is added to this limit 2
Soldering heat resistance change -0.5 0.5 % Printed as ±(0.5%+0.0005Ω), the 0.0005 Ω absolute term is added to this limit; test conditions not printed 2
Thermal shock resistance change -0.5 0.5 % Printed as ±(0.5%+0.0005Ω), the 0.0005 Ω absolute term is added to this limit; test conditions not printed 2
Load life resistance change -1 1 % Printed as ±(1%+0.0005Ω), the 0.0005 Ω absolute term is added to this limit; test conditions not printed 2
Standard operating temperature -55 170 °C Standard operating temperature range 1
Resistance tolerance (F code = ±1%) -1 1 % Tolerance code F in part number 2
Nominal resistance (decoded from part number) R 5 mΩ Decoded from 500N in part number (500 × 10^-5 Ω); matches the 5mΩ example in the ordering procedure 2
Rated power (wattage code 2W) 2 W Decoded from wattage code 2W in part number 2

CAD (KiCad official)

  • Symbol: LR122WF800NT4E
  • Footprint: Resistor_SMD:R_2512_6332Metric
  • 3D model: 2512 (KiCad packages3D, STEP)
  • 3D model files: lr122wf800nt4e-etched.step / lr122wf800nt4e-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lr122wf800nt4e.step / lr122wf800nt4e.glb are the bare package body.
