ABOUT CSM (Low Ohm Value 1 mΩ to 200 mΩ)

New high-precision Bulk Metal® surface-mount Power Metal Strip® resistor of 1 mΩ to 200 mΩ that features an improved load-life stability of ± 0.2 % at + 70 °C for 2000 h at rated power, an absolute TCR of ± 15 ppm/°C maximum from - 55 °C to + 125 °C, + 25 °C ref., and a tolerance of ± 0.1 %.
Typical current sensing resistors offer a load-life stability of ≥ 1 % through a 2000 h workload. The improved resistance stability of the CSM Series makes it ideal for tightened-stability voltage division and precision current sensing applications in switching linear power supplies, power amplifiers, measurement instrumentation, bridge networks, and medical and test equipment. In addition, the CSM Series complies with EEE-INST-002 (MIL-PRF 55342 and MIL-PRF 49465) for military and space applications.

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 foil@vishaypg.com
• For better performance please contact Application Engineering
• Compliant to RoHS directive 2002/95/EC
