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