FEATURES
* Fusible resistor for constant current designed for overload protection * High positive temperature coefficient * Flame retardant coating * Defined switch-off behaviour * Pure tin termination on nickel barrier, plated on fress fit steel caps * Compatible with lead (Pb)-free and lead containing soldering processes * Lead (Pb)-free and RoHS compliant
STANDARD ELECTRICAL SPECIFICATIONS
MODEL NMM0207SI NMM0207SI POWER RATING1) P70 W 0.35 0.35 TEMPERATURE COEFFICIENT ppm/K + 4500 ( 500) + 4500 ( 500) TOLERANCE % 5, 10, 20 10, 20 RESISTANCE RANGE 1R0 - 47R R10 - R91 E-SERIES 12 - 24 12
Note 1. Permissible dissipation depends on the maximum temperature at the solder point, the component placement density and the substrate material.
* Marking: additional 5th band black; According to IEC 60062; see also datasheet "surface mount resistor marking" (document number: 20020)
