Vishay Beyschlag
High Precision Leaded Resistors
FEATURES
Superior thin film technology
DESCRIPTION
UXA 0204, UXB 0207 and UXE 0414 high precision leadedthin film resistors combine the proven reliability of theprofessional products with an exceptional level of precisionand stability. Therefore they are perfectly suited forapplications in the fields of precision test and measuringequipment and particularly for the design of calibrationreferences and standards.
Exceptional low TCR: ± 02 ppm/K to ± 10 ppm/KSuper tight tolerance: ± 0.01 % to ± 0.25 %Exceptional overall stability: class 0.02Wide resistance range: 22 Ω to 1 MΩLead (Pb)-free solder contacts
Pure tin plating provides compatibility with lead (Pb)-freeand lead containing soldering processes
Compatible with “Restriction of the use of HazardousSubstances” (RoHS) directive 2002/95/EC (issue 2004)
