Our application engineering department is available to advise and to make recommendations. For non-standard technical requirements and special applications, please contact us. FIGURE 1 - Z203 ON A PC BOARD A (1) Connection Distant from Solder Point PCB A A-A Note (1) The leads on the Z203 connect to the Bulk Metal® Foil resistive element at the top of the package using solder-free, all welded construction. This high-reliability enhancement protects the terminations from initial board-assembly and subsequent board flexation stresses. The welded construction completely eliminates the possibility of latent failures due to solder reflow and solder-starved internal connections.

This is, place metrology-grade resistors right into the equipment as on-board reference standards. Vishay’s Z203 unit offers an immediate answer to many resistor applications currently believed unsolvable, and opens entirely new areas of design where the use of resistors had not been considered. Applications include:  Secondary standards  Feedback devices for operational amplifiers  Precision voltage dividers  Meter multipliers  Precision bridge resistors  Decade voltage dividers The performance of Vishay’s Z203 resistor cannot be equaled by any conventional resistor technologies, or by bulky units now used as standards. As shown by the specifications on table 2 and 3, there is no compromise between precision and speed (as in wirewound units) or between speed and the combination of excellent precision, stability and TCR (as with conventional deposited films). FIGURE 3 - TRIMMING TO VALUES (conceptual illustration) The Z203 is the result of a unique concept in resistor manufacturing. A proprietary new generation of the Bulk Metal® Z-Foil element with known and controllable properties is applied to a special ceramic substrate. A resistive pattern is then photoetched by an ultra-fine technique developed by Vishay. The device’s etched planar construction results in the extremely low and reproducible reactance needed for high-frequency and pulse applications. Z203 is uniquely enhanced by post manufacturing operations (PMO) exercised after the manufacturing cycle has been completed. Some of these exercises are a standard part of the manufacturing cycle and are only repeated during the PMO cycle to gain added stability or confidence in the product. The foil resistor load-life curve shows an increase in resistance from the first load application, but flattens out to no further change after the first few hundred hours of loading. This knee in the load-life curve is reduced significantly by a special accelerated load-life operation performed by Vishay, resulting in a flat response immediately after installation. Other resistive devices show a continuous change when subjected to these same stresses and are driven out of tolerance. The optional PMO for this product includes the combination of thermal shock, power shot and special burn-in.

This calls for more than just selecting a standard device and applying it to a circuit. The standard device may turn out to be all that is needed but an analysis of the projected service conditions should be made and it may well dictate a routine of stabilization known as post manufacturing operations or PMO. The PMO operations that will be discussed are only applicable to Bulk Metal Foil resistors. They stabilize Bulk Metal Foil resistors while they may be harmful to other types. Short time overload, accelerated load life, and temperature cycling are the three PMO methods that do the most to remove the anomalies down the road. Vishay Bulk Metal Foil resistors are inherently stable as manufactured. These PMO methods are only of value on Bulk Metal Foil resistors and they improve the performance by amounts that are small but significant when compared to the very tight tolerances. Users are encouraged to contact Vishay Foil applications engineering for assistance in choosing the PMO operations that are right for their application. www.foilresistors.com 4 For any questions, contact: foil@vishaypg.com Document Number: 63186 Revision: 29-Mar-10 Z203 (Z1-Foil) Vishay Foil Resistors TABLE 4 - GLOBAL PART NUMBER INFORMATION (1) NEW GLOBAL PART NUMBER: Y1445250R000V9L (preferred part number format) DENOTES PRECISION VALUE CHARACTERISTICS Y R= K = k 0 = standard 9 = lead (Pb)-free 1 to 999 = custom Y 1 4 4 5 2 5 0 R 0 0 0 V 9 PRODUCT CODE RESISTANCE TOLERANCE PACKAGING 1445 = Z203 1446 = Z203L (2) V = ± 0.005 % T = ± 0.01 % Q = ± 0.02 % A = ± 0.05 % B = ± 0.1 % C = ± 0.25 % D = ± 0.5 % F = ± 1.0 % L = bulk L FOR EXAMPLE: ABOVE GLOBAL ORDER Y1445 250R000 V 9 L: TYPE: Z203 VALUE: 250.0  ABSOLUTE TOLERANCE: ± 0.005 % TERMINATION: lead (Pb)-free PACKAGING: bulk HISTORICAL PART NUMBER: Z203T 250R00 V B (will continue to be used) Z203 MODEL Z203 Z203L (2) T 250R00 V B TERMINATION OHMIC VALUE ABS.
