| VSMD1505 Vishay Foil Resistors SURFACE MOUNT Bulk Metal(R) Foil Technology Miniature, Ultimate Tracking Surface Mount Divider FEATURES Product may not be to scale * * * * * * * * This extremely small surface mount voltage divider made of Bulk Metal(R) Foil technology offers the ultimate in tracking and ultimate in ratio stability. Additionally Bulk Metal(R) Foil has an extremely low absolute temperature coefficient of resistance so the temperature differential caused by power unbalances associated with large ratios will not adversely affect the tracking specification. The absence of noise generation by the resistor make it the ultimate component. Ratio Tracking: to 0.1ppm/C Ratio Match Tolerance: to 0.005% Absolute Tolerance: to 0.01% Nominal TCR: + 0.6ppm/C (0 to 25C) - 0.6ppm/C (25 to 60C) Resistance Value Ratios 1:1 to 1:20 Non Inductive Planar Design Current Noise: < - 40dB Load Life (Ratio Stability): < 0.01% TABLE 1 - RESISTANCE VALUES/ RATIO CHARACTERISTICS RATIOS R1/R2 10K/10K 5K/10K 2.5K/10K 2.0K/10K 1.0K/9K AVAILABLE RATIO TRACKING 0.1ppm/C 0.1ppm/C 0.3ppm/C 0.3ppm/C 0.5ppm/C 0.5ppm/C 0.5ppm/C BEST RATIO MATCH TOLERANCE 0.005% 0.005% 0.01% 0.01% 0.02% 0.02% 0.02% FIGURE 1 - VISHAY VSMD1505 NOMINAL TCR (0C TO +60C) Temperature (C) +100 0 +25 +60 1:1 1:2 1:4 1:5 1:9 1:10 1:20 Nominal Resistance/ Temperature (RT) Curve Maximum Spread 2.5 ppm/C (3) Standard Spread 1.5 ppm/C R 0 R (ppm) 1.0K/10K 500/10K +0.6 ppm/C Nominal Chord Slope (TCR) -100 -0.6 ppm/C Nominal Chord Slope (TCR) TABLE 2 - TYPICAL PERFORMANCE SPECIFICATIONS TEST MIL-PRF-55342G CHARACTERISTIC E R LIMITS 0.10% 0.10% 0.10% 0.10% 0.20% 0.20% -- VSM MAXIMUM R LIMITS* 0.02% 0.02% 0.02% 0.05% 0.05% 0.10% 0.01% 0C / +25C / +60C are the test points with +25C as the reference temperature FIGURE 2 - DELTA RATIO VERSUS TEMPERATURE 10 8 Thermal Shock Low Temperature Operation Short Time Overload Delta Ratio (ppm) 6 4 2 0 -2 -4 -6 - 55 - 35 - 15 5 1K/10Kohms (typical) High Temperature Exposure Resistance to Bonding Moisture Resistance 10K/10Kohms (typical) Load Life (Ratio Stability) *R's plus additional 0.0005 ohm for measurement error.
