VRM
Vishay Foil Resistors
Bulk Metal® Foil Technology Industrial Miniature Precision
Resistor with TCR of ꢀ ꢁꢁpm/C and Tolerance to ꢂ0ꢂꢃ ꢄ
FEATURES
• Temperature Coefficient of Resistance:
4 ppm/°C (0 °C to + 60 °C);
8 ppm/°C (- 55 °C to + 125 °C, 25 °C Ref.)
• Resistance Range: 5 Ω to 50 kΩ
• Tolerance: to 0.01 %
• Power Rating: 0.25 W at + 70 °C; 0.125 W at + 125 °C
Any value at any tolerance available with resistance range
• Load Life Stability: 0.05 % Maximum ΔR at + 70 °C at
Rated Power for 2000 hours
The VRM style is a miniaturized version of the now famous
S102C. It is made with a Bulk Metal® Foil element so it
retains all of the inherent performance of foil resistors. It does
not, however, have the value range, power rating, TCR or
lead spacing of the S102C. It is a size for size replacement
for certain wirewounds and finds application in situations
where size constraints dictate the use of this miniature
precision resistor.
• Non Inductive: < 0.08 µH
• Thermal EMF: < 0.1 µV/°C
• Long Term Stability: 0.0025 % (25 ppm) per year under
low power and room temperature conditions
• Voltage Coefficient: < 0.1 ppm/V
• Maximum Working Voltage: 250 V
• Terminal Finishes Available: Lead (Pb)-free
Tin/Lead Alloy
Our Application Engineering Department is available to
advise and to make recommendations. For non-standard
technical requirements and special applications, please
contact us.
• Any value available within resistance range (e.g. 1K234)
• Prototype samples available from 48 hours. For more
information, please contact foil@vishaypg.com
• For better performances, please see S-Series datasheet
