Applications

The SMT current sensing precision resistor series from Isabellenhütte offers the designer higher power ratings and low internal temperature rises due to the larger pad termination sizes. The MANGANIN® alloy resistance element has a resistance range of 0.004Ω to 4.7Ω, TCR of <50 ppm/°C for values ≥0.010Ω and <100 ppm/°C for values <0.010Ω (between +20°C and +60°C) and offers excellent long term stability. The SMT model offers these capabilities in a 2817 chip size.

  • Current sensing precision resistor
  • 2-terminal surface-mount design in a 2817 chip size
  • Resistance range from 0.004Ω to 4.7Ω
  • Tolerances of ±0.5%, ±1%, ±2% and ±5%
  • TCR from <50±ppm/°C (≥0.010Ω) (+20°C to +60°C)
  • Power rating up to 7W (at +70°C)
  • Constant current up to 35A (0.004Ω)
  • Temperature range from -65°C to +170°C
  • Inductance of <3nH
  • Stability of <0.5% (TK=75°C) / <1% (TK=105°C)
    for values <1Ω (at rated power, deviation after 2000h)
  • Dielectric withstanding voltage of 200V AC/DC
  • AEC-Q200 qualified

 

Typical applications for the SMT current sensing precision resistor series include:

  • Current sensor for power hybrid applications
  • Control systems for the automotive market
  • Power modules
  • Frequency converters
  • Switch-mode power supplies
