Zero-Ohm-Resistor: OMM0204-MS1 Rmax = 10mΩ I
max = 2A
1) Power rating depends on the maximum temperature at the
solder point, the component placement density and the
substrate material
2) Rated voltage:
3) Values below 10 ¾ on request
4) Low inductive trim for high frequency application
• Further values and tolerances on request
• Coating:
Light green for TC= 100ppm/K, 50ppm/K and zero ohm resistor
Pink TC = 25ppm/K
Violet TC = 15ppm/K
Beige HF version
• Marking : see appropriate catalog or web page
• Zero ohm resistor has a black band only
