VSM0805
Vishay Foil Resistors
Bulk Metal® Foil Technology
Discrete Surface Mount Chip Resistors
FEATURES
• Nominal TCR: + 0.6ppm/°C (0 to 25°C)
- 0.6ppm/C° (+ 25°C to + 60°C)
+ 2.2ppm/°C (- 55°C to + 25°C)
- 1.8ppm/°C (+ 25°C to + 125°C)
Product may not
be to scale
• Absolute Tolerance: to ± 0.01%
• Resistance Range: 5.5Ω to 12K
• Load Life Stability: ± 0.025% (2000 hours @ 70°C)
• Shelf Life Stability: 0.005% Maximum ∆R
The VSM0805 represents the latest addition and smallest size • Voltage Coefficient: < 0.00001%/volt (< 0.1ppm/V)
to the Precision Bulk Metal® Foil (BMF) technology surface • Current Noise: < - 40dB
mount chip resistor series. The VSM0805 has a conventional
full wrap around termination.
The BMF technology offers designers the lowest and most
predictable absolute Temperature Coefficient Resistance
• Non Inductive: < 0.08µH
• Terminal Finishes Available:
Lead (Pb)-free (Sn 99.3% Cu 0.7%)
Tin/Lead Alloy (Sn 62% Pb 36% Ag 2%)
available. The TCR is a process capability not a selection
process and for the most part is independent of ohmic value
and lot related variations.
