VCS1610Z (Kelvin Connection) Vishay Foil Resistors High Precision Foil Surface Mount Current Sensing Chip Resistors with TCR of ± 0.2 ppm/°C, Load Life Stability of ± 0.015 %, ESD Immunity up to 25 kV and Fast Thermal Stabilization FEATURES INTRODUCTION The Z-foil technology provides a significant reduction of the resistive component’s sensitivity to ambient temperature variations (TCR) and applied power changes (PCR). Designers can now guarantee a high degree of stability and accuracy in fixed-resistor applications using solutions based on Vishay‘s Foil Resistors revolutionary Z-foil technology. Model VCS1610Z is a surface mount chip resistor designed with 4 pads for Kelvin connection. Utilizing Vishay’s Bulk Metal® Z-foil as the resistance element, it provides performance capabilities far greater than other resistor technologies can supply in a product of comparable size. ± 0.2 ppm/°C typical TCR (- 55 °C to + 125 °C,+ 25 °C ref.) removes errors due to temperature gradients. This small device dissipates heat almost entirely through the pads so surface mount users are encouraged to be generous with the board’s pads and traces.

Four-terminal connections or Kelvin connections are required in these low ohmic value resistors to measure a precise voltage drop across the resistive element. The 4-terminal configuration eliminates the IR-drop error voltage that would be present in the voltage sense leads if a standard two-terminal resistor were used. In current sense resistors the contact resistance and the terminations resistance may be greater than that of the resistive element itself so lead connection errors can be significant if only two terminal connections are used. Why is the VCS1610Z vital in avoiding Thermal EMF (parasitic effect)? When two dissimilar metals are heated, a parasitic voltage is generated and creates a DC-offset error. This voltage is proportional to a temperature difference between either end of the pair of conductors. This phenomenon is called a Thermal Electro-motive Force (Thermal EMF), or thermocouple effect. Thermal EMF is an important consideration in low ohmic current sensing resistors used mostly in DC circuits. The VCS1610Z is the ideal solution to minimize the effect of thermal EMF through the use of appropriate materials between the resistive layer and the terminations. Should I be concerned about the impact of ESD on my resistor? Electrostatic Discharge (ESD) is known to produce catastrophic failures in thin-film and thick-film (cermet) resistors at only 3000 V. On the other hand, the Bulk Metal® Foil resistor withstands ESD events up to 25 kV because its thicker resistance element and greater metallic mass afford much higher energy-handling capability than either the much thinner thin-film resistor or the sparse, non-homogeneous metallic content of the thick film resistor. Should I be concerned about stability? In order to select the resistor technology most appropriate to the application, a designer must take into account all normal and extraordinary stresses the resistor will experience in the application. In addition, the designer must consider the cost and reliability impact involved when it becomes necessary to add costly additional compensating circuitry when inadequate resistors are selected. The stability of Bulk Metal® Foil resistors, together with the advantages already mentioned, as well as the other basic advantages apparent in their specifications will not only provide unequalled performance in the circuit but will eliminate all the costs associated with extra compensation circuitry. With VCS1610Z, only a minimal shift in resistance value will occur during its entire lifetime. Most of this shift takes place during the first few hundred hours of operation, and virtually no change is noted thereafter.  FIGURE 2 - TRIMMING TO VALUES(Conceptual Illustration)* Current Path Before Trimming Current Path After Trimming Trimming Process Removes this Material from Shorting Strip Area Changing Current Path and Increasing Resistance NOTE: Foil shown in black, etched spaces in white * To acquire a precision resistance value, the Bulk Metal® Foil chip is trimmed by selectively removing built-in “shorting bars.” To increase the resistance in known increments, marked areas are cut, producing progressively smaller increases in resistance. This method eliminates the effect of “hot spot” and assures the long term stability of the Foil chips. www.vishayfoilresistors.com 2 For any questions, contact: foil@vishaypg.com Document Number: 63226 Revision: 6-Jul-12 VCS1610Z (Kelvin Connection) Vishay Foil Resistors 0.110 (2.794) FIGURE 3 - DIMENSIONS in inches (millimeters) 4 Mounting A Pads(1) L H I2 E1 E2 I1 B 0.060 (1.524) 0.020 (0.508) E2 I1 R W 0.200 (5.08) Bottom View Top View E1 I2 Electrical Schematic Solder Pad Layout Note (1) I and E mounting pads are interchangeable L  INCHES MILLIMETERS 0.160 ± 0.010 4.06 ± 0.25 H 0.100 ± 0.010 2.54 ± 0.25 W 0.040 maximum 1.02 maximum A 0.045 ± 0.005 1.14 ± 0.13 B 0.030 ± 0.010 0.76 ± 0.25 FIGURE 4 - TYPICAL RESISTANCE/TEMPERATURE CURVE + 500 + 400 + 300 + 200 + 100 ΔR 0 R (ppm) - 100 0.05 ppm/°C - 200 - 0.1 ppm/°C - 300 0.1 ppm/°C 0.14 ppm/°C - 400 - 0.16 ppm/°C 0.2 ppm/°C - 500 - 55 - 25 0 + 25 + 60 + 75 + 100 + 125 Ambient Temperature (°C) TABLE 2 - PERFORMANCE SPECIFICATIONS TEST Thermal Shock 5 x (- 65 °C to + 150 °C) MIL-PRF-55342 R LIMITS TYPICAL R LIMITS* ± 0.10 % ± 0.005 % (50 ppm) Low Temperature Operation, - 65 °C, 45 min at Pnom ± 0.10 % ± 0.005 % (50 ppm) Short Time Overload, 6.25 x Rated Power, 5 sec ± 0.10 % ± 0.005 % (50 ppm) High Temperature Exposure, + 150 °C, 100 h ± 0.10 % ± 0.01 % (100 ppm) Resistance to Soldering Heat, +245°C for 5 sec,+235°C for 30 sec ± 0.2 % ± 0.01 % (100 ppm) Moisture Resistance ± 0.2 % ± 0.01 % (100 ppm) Load Life Stability + 70 °C for 2000 h at Rated Power ± 0.5 % ± 0.015 % (150ppm) Note * Measurement error 0.001 R  Document Number: 63226 Revision: 6-Jul-12 For any questions, contact: foil@vishaypg.com www.vishayfoilresistors.com 3 VCS1610Z (Kelvin Connection) Vishay Foil Resistors FIGURE 5 - HIGH TEMPERATURE EXPOSURE High Temperature Exposure VCS1610Z, 1R; +150°C, 100 hrs ; n=10 300 250 200 150 100 50 R (ppm) 0 -50 0 1 2 3 4 5 6 7 8 9 10 1600 1800 2000 -100 -150 -200 -250 -300 Resistor Serial Number  FIGURE 6 - LOAD LIFE LOAD LIFE VCS1610Z, 1R ; 0.25W @ +70C, 2000 hrs ; n=15 300 250 200 150 100 50 R (ppm) 0 -50 0 200 400 600 800 1000 1200 1400 -100 -150 -200 -250 -300 Time (hrs)  www.vishayfoilresistors.com 4 For any questions, contact: foil@vishaypg.com Document Number: 63226 Revision: 6-Jul-12 VCS1610Z (Kelvin Connection) Vishay Foil Resistors FIGURE 7 - LOW TEMPERATURE OPERATION Low Temperature Operation VCS1610Z 0R2; -65°C, 45 min at 0.25W, n=10 300 250 200 150 100 R (ppm) 50 0 -50 0 1 2 3 4 5 6 7 8 9 10 9 10 -100 -150 -200 -250 -300 Resistor Serial Number  FIGURE 8 - SHORT TIME OVERLOAD Short Time Overload VCS1610Z 0R2; 6.25 x Rated Power, 5 sec ; n=10 300 250 200 150 100 50 R (ppm) 0 -50 0 1 2 3 4 5 6 7 8 -100 -150 -200 -250 -300 Resistor Serial Number www.vishayfoilresistors.com 5 For any questions, contact: foil@vishaypg.com Document Number: 63226 Revision: 6-Jul-12 VCS1610Z (Kelvin Connection) Vishay Foil Resistors TABLE 3 - GLOBAL PART NUMBER INFORMATION (1) NEW GLOBAL PART NUMBER: Y11190R40500D9W (preferred part number format) DENOTES PRECISION VALUE CHARACTERISTICS Y R= 0 = tin/lead plated 9 = tin plated 19 = gold plated 1 to 999 = custom Y 1 1 1 9 0 PRODUCT CODE R 4 0 5 RESISTANCE TOLERANCE D F G J K 1119 = VCS1610Z = ± 0.5 % = ± 1.0 % = ± 2.0 % = ± 5.0 % = ± 10.0 % 0 0 D 9 W PACKAGING W = waffle pack R = tape and reel FOR EXAMPLE: ABOVE GLOBAL ORDER Y1119 0R40500 D 9 W: TYPE: VCS1610Z VALUES: 0.405  ABSOLUTE TOLERANCE: ± 0.5 % TERMINATION: tin plated, lead-free (Pb-free) PACKAGING: waffle pack Note (1) For non-standard requests or additional values, please contact application engineering. www.vishayfoilresistors.com 6 For any questions, contact: foil@vishaypg.com Document Number: 63226 Revision: 6-Jul-12 Legal Disclaimer Notice Vishay Precision Group, Inc.
