Marking

The component is laser marked with “3920”, alloy type, ohmic value 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.

Processing

LRMAP3920 series resistors are suitable for IR reﬂow soldering. The recommended reﬂow proﬁle for Pb-free soldering, for example using SAC387 alloy (Sn

95.5%, Ag 3.8%, Cu 0.7%), is as follows:

Pre-heat: 30s to 45s at 180°C

Soldering: 20s to 40s at 250°C

Peak: 260°C

Packaging

LRMAP3920 resistors are packed in 16mm plasꢀc tape, 3000 pieces per reel.
