Offering a resistance range from 0.25Ω to 500Ω, the VCS232Z Z-Foil power current sensing resistor specifies a TCR of ±0.05 ppm/°C from 0°C to +60°C and ±0.2 ppm/°C from -55°C to +125°C, at a +25°C reference. Tolerance is ±0.02% and load life stability is ±0.005% (50 ppm) at +25°C for 2,000 hours at rated power. For high-power applications, the VCS232Z offers a power rating of 2W (free air) at +25°C. Available with lead-free or tin/lead alloy terminations, pricing starts at $9.32 each. VISHAY INTERTECHNOLOGY, INC., Malvern, PA. (619) 336-0860.
