VFC1206

Vishay Foil Resistors

High Precision Flip Chip,

Patents Pending (Industrialized Countries)

FEATURES

• Nominal TCR: 0.5ppm/°C (- 55°C to + 125°C)

• Resistance Range: 10Ω to 30K

• Tolerance: to ± 0.01%

Product may not

be to scale

• Load Life Stability: ± 0.01% maximum ∆R under full rated

power at + 70°C for 2000 hours

• Shelf Life Stability: 50ppm (0.005%) over several years

• Voltage Coefficient: < 0.00001%/volt (< 0.1ppm/V)

• Current Noise: < 0.010µV (rms)/volt of applied voltage

• Non Inductive: < 0.08µH

The VFC1206 is a surface mountable flip chip resistor that

TABLE 1 - RESISTANCE VALUE VS

TOLERANCE AND TCR

utilizes Ultra Precision Bulk Metal^®“Z” Foil. This product differs

from other Vishay Bulk Metal^®Foil surface mount devices in

as much as it is installed with the foil side facing the PCB

providing better power handling capabilities. The Foil

element is isolated from the PCB by a protective overcoating.

This overcoating plus the overall product design isolates the

resistor from handling and installation stresses.

The temperature coefficient of resistance (TCR) curve shown

below compares the new revolutionary “Z” Foil with its TCR of

< 0.5ppm/°C to the original Vishay “C” Foil. The Bulk Metal^®

Foil characteristics of excellent long term stability, low noise

and availability of tight tolerance are maintained in this Flip

Chip configuration. The VFC1206 is available in any value

within the specified resistance range. The flip chip configuration

is more economical for high volume, anolog applications where

high precision is required.
