FEATURES

• 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 %

• 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 m

Ω vs. 2 mΩ)

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

• Short time overload: ± 0.1 % typical

• 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

• Screening in accordance with EEE-INST002 available

(per MIL-PRF-55342 and MIL-PRF-49465; see 303144

and 303145 datasheets)

• Terminal finishes available: lead (Pb)-free, tin/lead alloy

• Prototype quantities available in just 5 working days

or sooner. For more information, please contact

• For better performance please contact Application

Engineering

• Compliant to RoHS directive 2002/95/EC
