Vishay Foil Resistors

Bulk Metal^®Technology High Precision, Current Sensing, Power

Surface Mount, Metal Strip Resistor with Resistance Value from 1 m

Rated Power up to 3 W and TCR to 0 ± 15 ppm/°C Maximum

FEATURES

Ω,

• Temperature coefficient of resistance:

± 15 ppm/°C max. (- 55 °C to + 125 °C, + 25 °C

ref.); ± 10 ppm/°C max. (- 55 °C to + 125 °C,

+ 25 °C ref.) is available on request (see table 1)

• Power rating: 1 W to 3 W

• Resistance tolerance: ± 0.1 %

• Resistance range: 1 mΩ to 200 mΩ ⁽¹⁾

No minimum order quantity and any value at any

tolerance available within resistance range.

• Vishay Foil resistors are not restricted to standard values,

specific “as required” values can be supplied at no extra

cost or delivery (e.g. 2.3456 mΩ vs. 2 mΩ)

• Load life stability to ± 0.2 % (70 °C, 2000 h at rated power)

• Short time overload: ± 0.1 % typical

Vishay Foil Resistors’ application engineering department is

available to advise and make recommendations.

For non-standard technical requirements and special

applications, please contact foil@vishaypg.com.

• Thermal EMF: 3 µV/°C (DC offset error, significant for low

values)

• Maximum current: up to 54 A

• Proprietary processing techniques produce low TCR, tight

tolerance and improve stability

• Low inductance < 5 nH

• Solderable terminations

• Excellent frequency response to 50 MHz

• Matched sets are available on request

Zin

∞

Four terminal (Kelvin) design: allows for precise and

accurate measurements.
