LCM0207SI

Vishay Draloric

FEATURES

• Fusible resistor for constant voltage designed for

overload protection

• Specially spiralled to provide the fusible function

• Flame retardant coating

• Used in battery chargers, TV-sets, cordless phones,

PC/CPU-cooler

• Pure tin termination on nickel barrier, plated on press fit

steel caps

• Compatible with lead (Pb)-free and lead containing

soldering processes

• Lead (Pb)-free and RoHS compliant

Note

1. Permissible dissipation depends on the maximum temperature at

the solder point, the component placement density and the

substrate material.

• Marking: According to IEC 60062; see also datasheet “surface

mount resistor marking” (document number: 20020)
