Zero-Ohm-Resistor: OMM0204 Rmax = 10 mΩ I
max = 2 A
Note
1. Permissible dissipation depends on the maximum temperature
at the solder point, the component placement density and the
substrate material.
2. Rated voltage: .
• Further values and tolerances on request
• Coating:
Light green for TC = 100 ppm/K, 50 ppm/K and zero ohm resistor
Pink TC = 25 ppm/K
Violet TC = 15 ppm/K
• Marking: According to IEC 60062; see also data sheet “surface
mount resistor marking” (document number: 20020)
• Zero ohm resistor has a black band only
PxR
Note
3. Based on measurements on test board acc. to EN 140400.
