4 / 9 page Document Number: 28726 For technical questions, contact: ff3cresistors@vishay.com www.vishay.com Revision: 21-Aug-07 87 UXA 0204, UXB 0207, UXE 0414 High Precision Leaded Resistors Vishay Beyschlag Notes: (1) Resistance values to be selected from the E192 series, for other values please contact the factory. (2) TCR 10 and TCR 05 are specified over the temperature range from - 20 °C to + 85 °C. (3) TCR 02 is specified over the temperature range from 0 °C to + 60 °C. DESCRIPTION Production is strictly controlled and follows an extensive set of instructions established for reproducibility. A homogeneous film of metal alloy is deposited on a high grade ceramic body (85 % 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. 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. ASSEMBLY 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. 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 PACKAGING MODEL REEL BOX BANDOLIER ON REEL CODE PIECES/BOX CODE UXA 1000 R1 100 1000 CU C1 UXB 1000 5000 R1 RP 100 1000 CU C1 UXE 2500 R2 100 1000 CU C1 TEMPERATURE COEFFICIENT AND RESISTANCE RANGE DESCRIPTION RESISTANCE VALUE (1) TCR TOLERANCE UXA 0204 UXB 0207 UXE 0414 ± 10 ppm/K (2) ± 0.25 % 22 Ω to 221 kΩ 10 Ω to 1 MΩ - ± 0.1 % 43 Ω to 221 kΩ 10 Ω to 1 MΩ 22 Ω to 511 kΩ ± 0.05 % 100 Ω to 180 kΩ 24 Ω to 301 kΩ 100 Ω to 301 kΩ ± 0.01 % 200 Ω to 150 kΩ 24 Ω to 301 kΩ - ± 05 ppm/K (2) ± 0.25 % 47 Ω to 150 kΩ 10 Ω to 1 MΩ - ± 0.1 % 47 Ω to 150 kΩ 10 Ω to 1 MΩ 47 Ω to 301 kΩ ± 0.05 % 100 Ω to 150 kΩ 24 Ω to 221 kΩ 100 Ω to 301 kΩ ± 0.01 % 200 Ω to 150 kΩ 24 Ω to 221 kΩ - ± 02 ppm/K (3) ± 0.25 % 100 Ω to 100 kΩ 100 Ω to 150 kΩ - ± 0.1 % 100 Ω to 100 kΩ 100 Ω to 150 kΩ - ± 0.05 % 150 Ω to 100 kΩ 150 Ω to 150 kΩ - ± 0.01 % 200 Ω to 100 kΩ 200 Ω to 150 kΩ - |
