FEATURES
•Convex terminal array available with either
scalloped corners (E version) or square corners
(S version)
•Wide ohmic range: 10R to 1M0
•4, 8, 10 or 16 terminal package with isolated resistors
•Lead (Pb)-free solder contacts on Ni barrier layer
•Pure tin plating provides compatibility with lead (Pb)-free
and lead containing soldering processes
•Compatible with “Restriction of the use of Hazardous
Substances” (RoHS) directive 2002/95/EC (issue 2004)
Notes
(1) Rated voltage:
(2) The power dissiaption on the resistor generates a temperature rise against the local ambient, depending on the heat flow support of the
printed-circuit board (thermal resistance). The rated dissipation applies only if permitted film temperature of 155 °C is not exceeded.
Notes
(3) Preferred way for ordering products is by use of the PART NUMBER
(4) Please refer to table PACKAGING, see next page
