CRA04S
Vishay
Thick Film Resistor Array
FEATURES
* Convex terminal array with square corners * * * * Wide ohmic ramge: 10R to 1M0 4 or 8 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)
The CRA04S thick film resistor array is constructed on a high grade ceramic body with convex terminations. A small package enables the design of high density circuits. The single component reduces board space, component counts, and assembly costs.

Notes (1) Rated voltage: P x R (2) The power dissipation 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 rate dissipation applies only if the permitted film temperature of 155 C is not exceeded.
