VFB1012D (Z-Foil)
Vishay Foil Resistors
Ultra High Precision Z-Foil BGA Surface Mount Voltage Divider
with 0.1 ppm/°C TCR Tracking, 0.01 % Tolerance Match and
Power Coefficient Tracking of 5 ppm at Rated Power
FEATURES
• Temperature Coefficient of Resistance (TCR):
Absolute:
Pb-free
Available
0.05 ppm/°C typical (0 °C to + 60 °C)
0.2 ppm/°C typical (- 55 °C to + 125 °C,
+ 25 °C Ref.)
RoHS*
COMPLIANT
Tracking: 0.1 ppm/°C typical
• Power Coefficient Tracking “ΔR due to self heating”: 5 ppm
at Rated Power
Any value and any ratio available within resistance range
• Power Rating: Entire Package: 0.2 W at 70 °C, Divided
between the two Resistors proportionally to their Value
INTRODUCTION
• Resistance Tolerance Match: 0.01 %
• Ratio Stability: 0.005 % (0.2 W at 70 °C, 2000 hours)
• Large Variety of Resistance Ratios: 1K to 10K
• Electrostatic Discharge (ESD) above 25 000 Volts
• Short Time Overload ≤ 0.005 %
Bulk Metal® Z-Foil Technology out-performs all other resistor
technologies available today for applications that require
ultra-high precision and ultra-high stability. 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).
• Non Inductive, Non Capacitive Design
• Rise Time: 1 ns without ringing
• Current Noise: < - 40 dB
• Voltage Coefficient: < 0.1 ppm/V
• Non Inductive: < 0.08 µH
Model VFB1012D offers low TCR (both absolute and
tracking), low PCR (both absolute and tracking), excellent
load life stability, tight tolerance, excellent ratio stability, and
low current noise, all in one package. 0.05 ppm/°C absolute
TCR removes errors due to temperature gradients.
• Non Hot Spot Design
• Terminal (solder ball) available: Lead (Pb)-free
Tin/Lead Alloy
• Maximum Working Voltage for each Element: 32 Volts
• For better performances please contact us
The VFB1012D Ball Grid Array (BGA) surface mount divider
provides tight tolerance matching and TCR tracking between
2 resistors simultaneously etched on one piece of foil on a
common substrate. The electrical specifications of this
integrated construction offers improved performances and
better real estate utilization over discrete resistors and
matched pairs.
APPLICATIONS
