High Precision Leaded Resistors
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.
FEATURES
Superior thin film technology
Exceptional low TCR: ± 02 ppm/K to ± 10 ppm/K
Super tight tolerance: ± 0.01 % to ± 0.25 %
Exceptional overall stability: class 0.02
Wide resistance range: 22
Ω
to 1 M
Ω
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 2002/95/EC (issue 2004)
APPLICATIONS
Precision test and measuring equipment
Design of calibration references and standards
