FEATURES
• Metal film resistor with high power rating
• Stable metal film on high quality ceramic
• Good thermal distribution
• Force fitted steel caps, tin plated on nickel barrier
• Reliable solderable terminations to facilitate surface mounting.
• Further values and tolerances on request
• Coating: light green
• Marking: see appropriate catalog or web page
• Zero ohm resistor has one black band only
1) Power rating depends on the maximum temperature at
the solder point, the component placement density and
the substrate material.
2) Rated voltage: PxR
