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)

12NC INFORMATION
Components may be ordered by using either a simple cleartext ordering code, see “Type Description and OrderingCode” or Vishay BCcomponents’ unique 12NC.Numeric Ordering Code (12NC)
The resistors have a 12-digit Part Number starting with2312.
The subsequent 4digits indicate the resistor type,specification and packaging; see the 12NC Part Numbertable.
The remaining 4digits indicate the resistance value:–The first 3digits indicate the resistance value.
–The last digit indicates the resistance decade inaccordance with the 12NC Indicating ResistanceDecade table.
