• Super tight tolerance: 0.01 % to 0.2ꢀ %
• Exceptional overall stability: class 0.02
• Wide resistance range: 22 Ω to 1 MΩ
• Lead (Pb)-free solder contacts
• 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 2002/9ꢀ/EC (issue 2004)
DESCRIPTION
UXA 0204, UXB 0207 and UXE 0414 high precision leaded
thin film resistors combine the proven reliability of the
professional products with an exceptional level of precision
and stability. Therefore they are perfectly suited for
applications in the fields of precision test and measuring
equipment and particularly for the design of calibration
references and standards.
APPLICATIONS
• Precision test and measuring equipment
• Design of calibration references and standards
