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

Numeric Ordering Code (12NC)  
• The resistors have a 12-digit Part Number starting with  
2312.  
• The subsequent 4 digits indicate the resistor type,  
specification and packaging; see the 12NC Part Number  
table.  
• The remaining 4 digits indicate the resistance value:  
– The first 3 digits indicate the resistance value.  
– The last digit indicates the resistance decade in  
accordance with the 12NC Indicating Resistance  
Decade table.  
12NC Example  
The Part Number of a UXA 0204 resistor, value 47 kΩ and  
TCR 10 with 0.1 % tolerance, supplied on bandolier in a  
box of 1000 units is: 2312 662 34703.

DESCRIPTION  
ASSEMBLY  
Production is strictly controlled and follows an extensive set  
The resistors are suitable for processing on automatic  
insertion equipment and cutting and bending machines.  
Excellent solderability is proven, even after extended  
storage. They are suitable for automatic soldering using  
wave or dipping. The encapsulation is resistant to all  
cleaning solvents commonly used in the electronics industry,  
including alcohols, esters and aqueous solutions. The  
suitability of conformal coatings, if applied, shall be qualified  
by appropriate means to ensure the long-term stability of the  
whole system.  
of instructions established for reproducibility.  
A
homogeneous film of metal alloy is deposited on a high grade  
ceramic body (8ꢀ % Al2O3) and conditioned to achieve the  
desired temperature coefficient. Nickel plated steel  
termination caps are firmly pressed on the metallized rods.  
Special laser devices are used repeatedly to achieve the  
target value by slowly and smoothly cutting a helical groove  
in the resistive layer without damaging the ceramics. A  
further conditioning is applied in order to stabilise the  
trimming result. Connecting wires of electrolytic copper  
plated with pure tin are welded to the termination caps. The  
resistors are covered by protective coating designed for  
electrical, mechanical and climatic protection.The  
terminations receive a final pure tin on nickel plating. Script  
marking designates the resistance value plus coded TCR  
and tolerance.  
APPROVALS  
Where applicable, the resistors are tested in accordance with  
CECC 40101-806 which refers to EN 60115-1 and  
EN 140100.  
Vishay BEYSCHLAG has achieved "Approval of  
Manufacturer" in accordance with EN 100114-1  
The result of the determined production is verified by an  
accelerated ageing (burn-in) and extensive testing  
procedure performed on 100 % of the individual resistors.  
Only accepted products are stuck directly on the adhesive  
tapes in accordance with IEC 60286-1.

TESTS AND REQUIREMENTS  
Essentially all tests are carried out in accordance with the  
following specifications:  
IEC 60068-1, ꢀ.3. Climatic category LCT/UCT/ꢀ6 (rated  
temperature range: Lower Category Temperature, Upper  
Category Temperature; damp heat, long term, ꢀ6 days) is  
valid.  
EN 140000/IEC 6011ꢀ-1, Generic specification (includes  
tests)  
Unless otherwise specified the following values apply:  
Temperature: 1ꢀ °C to 3ꢀ °C  
EN 140100/IEC 6011ꢀ-2, Sectional specification (includes  
schedule for qualification approval)  
CECC 40101-806, Detail specification (includes schedule for  
conformance inspection)  
Relative humidity: 4ꢀ % to 7ꢀ %  
Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar).  
Most of the components are approved in accordance with the  
European CECC-system, where applicable. The Test  
Procedures and Requirements table contains only the most  
important tests. For the full test schedule refer to the  
documents listed above. The testing also covers most of the  
requirements specified by EIA/IS-703 and JIS-C-ꢀ202.  
For testing the components are mounted on a test board in  
accordance with IEC 6011ꢀ-1, 4.31 unless otherwise  
specified.  
In the Test Procedures and Requirements table only the  
tests and requirements are listed with reference to the
