One of the most important parameters influencing stability is the Temperature Coefficient of Resistance (TCR). Although the TCR of Bulk Metal(R) Foil is considered extremely low, this characteristic has been further refined over the years. The VSMP Series utilizes ultra high precision Z Foil. The Z Foil technology provides a significant reduction of the resistive element's sensitivity to ambient temperature variations (TCR) and to self heating when power is applied (Power Coefficient of Resistance, or PCR). Along with the inherently low PCR and TCR, Z Foil technology also provides remarkably improved load life stability, low noise and tight tolerances. Vishay Foil Resistors' (VFR) application engineering department is available to advise and make recommendations.

To increase the resistance in known increments, marked areas are cut, producing progressively smaller increases in resistance.

By using an electrolytic 0.01 F capacitor charged to 1200VDC, a single pulse was performed on 30 units of 1206, 10 k of Surface Mount Bulk Metal(R) Foil resistor and Pulse Test Thin Film resistor. The units were allowed time to cool down, after which the resistance measurements were taken and Test Description displayed in ppm deviation from the initial reading. Latent Damage - occurs when the ESD event causes moderate damage to the device, which is not noticeable, as the device appears to be functioning correctly. However, the load life of the device has been dramatically reduced, and further degradation caused by operating stresses may cause the device to fail during service. Latent damage is the source for greatest concern, since it is very difficult to detect by re-measurement or by visual inspection, because damage may have occurred under the external coating. All parts baked at +125C for 1 hr and allowed to cool at room temperature for 1 hr, prior to testing. By using an electrolytic 0.01F capacitor charged to 1000 VDC, a single pulse was Test Description performed on 20 units of 1206: 100, 1K and 10K of Surface Mount Vishay Foil Resistor and Test Results Thin Film Resistor. The unit was allowed time to cool down, after which the resistance By using an electrolytic measurement was taken and displayed in ppm deviation from the initial reading. 500 pF capacitor charged up to 4500 V, pulses were performed on 10 units of 1206, 10 k of three different Surface Mount Chip Resistors technologies, with an initial voltage spike of 2500 V (Figure 10). The units were allowed time to cool down, after which the resistance measurements were taken and displayed in ppm deviation from the initial readings. Readings were then taken in 500 V increments up to 4500 V.

This failure does not directly pertain to functionality; thus a parametric failure may be present while the device is still functional. Catastrophic Damage - occurs when the ESD event causes the device to immediately stop functioning. This may occur after one or a number of ESD events with diverse causes, such as human body discharge or the mere presence of an electrostatic field. www.vishayfoilresistors.com 4 R Thick Film Thin Film Bulk Metal Foil 2500 V -2.7% 97% <0.005% 3000 V -4.2% 366% <0.005% 3500 V -6.2% Open <0.005% 4000 V -7.4% Open <0.005% 4500 V -8.6% Open <0.005% For any questions, contact foil@vpgsensors.com 4128-EN Rev 04-Mar-2020 VSMP Series (0603, 0805, 1206, 1506, 2010, 2512) (Z Foil) Table 7--Global Part Number Information(1) NEW GLOBAL PART NUMBER: Y162612K7560T9R (preferred part number format) DENOTES PRECISION VALUE Y 1 6 CHARACTERISTICS R= K = k Y 2 6 1 2 PRODUCT CODE 0 = standard 9 = lead (Pb)-free 1 to 999 = custom K 7 5 6 0 T RESISTANCE TOLERANCE R PACKAGING R = tape and reel W = waffle pack T = 0.01% Q = 0.02% A = 0.05% B = 0.10% C = 0.25% D = 0.5% F = 1.0% 1636 = VSMP0603 1624 = VSMP0805 1625 = VSMP1206 1626 = VSMP1506 1627 = VSMP2010 1637 = VSMP2018(2) 1628 = VSMP2512 9 FOR EXAMPLE: ABOVE GLOBAL ORDER Y1626 12K7560 T 9 R: TYPE: VSMP1506 VALUES: 12.7560 k ABSOLUTE TOLERANCE: 0.01% TERMINATION: lead (Pb)-free PACKAGING: tape and reel HISTORICAL PART NUMBER: VSMP1506 12K756 TCR0.2 T S T (will continue to be used) VSMP1506 12K756 TCR0.2 T S T MODEL RESISTANCE VALUE TCR CHARACTERISTICS TOLERANCE TERMINATION PACKAGING T = 0.01% Q = 0.02% A = 0.05% B = 0.10% C = 0.25% D = 0.5% F = 1.0% S = lead (Pb)-free B = tin/lead T = tape and reel W = waffle pack VSMP0603 VSMP0805 VSMP1206 VSMP1506 VSMP2010 VSMP2018(2) VSMP2512 (1) (2) 12.756 k For non-standard requests, please contact application engineering.
