Bulk Metal^®Foil Technology Industrial Miniature Precision

Resistor with TCR of ꢀ ꢁꢁpm/C and Tolerance to ꢂ0ꢂꢃ ꢄ

FEATURES

• Temperature Coefficient of Resistance:

Pb-free

4 ppm/°C (0 °C to + 60 °C);

Available

8 ppm/°C (- 55 °C to + 125 °C, 25 °C Ref.)

RoHS*

COMPLIANT

• 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

• Any value available within resistance range (e.g. 1K234)

• Prototype samples available from 48 hours. For more

information, please contact foil@vishay.com

• For better performances, please see S-Series datasheet
