INTRODUCTION
VCS232Z is the industry’s first device to provide high rated
power, excellent load life stability, and low TCR - all in one
resistor.
The Z-Foil Technology provides a significant reduction of the
resistive component’s sensitivity to ambient temperature
variations (TCR) and applied power changes (PCR).
• Power Rating at + 25 °C: 2 Watts
• Tolerance: to 0.02 %
• Load Life Stability: to 0.005 %, 25 °C for 2000 hours at
rated power
• Maximum Current: 3 Amps
The latest developments in Foil resistors technology have
reduced the temperature coefficient of Resistance (TCR):
0.05 ppm/°C Absolute TCR removes error due to
temperature gradients.
By taking advantage of the overall stability and reliability of
Vishay’s Bulk Metal® Z-Foil resistors, designers can
significantly reduce circuit errors and greatly improve overall
circuit performances.
• Resistance Range: 0.25 Ω to 500 Ω
• Electrostatic Discharge (ESD) above 25 000 Volts
• Short Time Overload ≤ 0.005 %
• Non Inductive, Non Capacitive Design
• Rise Time: 1 ns without ringing
• Current Noise < - 40 dB
Model VCS232Z is a 4 lead kelvin connected device.
• Thermal EMF: 0.05 µV/°C
Our Application Engineering Department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please
contact us.
• Voltage Coefficient < 0.1 ppm/V
• Non Inductive: 0.08 µH
• Non Hot Spot Design
• Terminal Finishes available: Lead (Pb)-free
