Marking

The component is laser marked with “3920”, alloy type, ohmic value (using R to indicate decimal posiꢀon in ohms) and tolerance.

Solvent Resistance

The component is resistant to all normal industrial cleaning solvents suitable for printed circuits.

Construcꢀon

The component is formed from a conꢀnuous band of E-beam welded precision resisꢀve strip. Various alloys are used based on the

resistance value.
