vcs1625z

Vishay Intertechnology introduced the new VCS1625Z ultra-high-precision Z-Foil surface-mount current sensing chip resistor. The new device provides an industrial-grade absolute TCR of ±0.05 ppm/°C from 0 °C to +60 °C and ±0.2 ppm/°C from −55 °C to +125 °C, +25 °C ref., an excellent power coefficient (“ΔR due to self heating”) of ±5 ppm at rated power, and a tolerance of ±0.2 %. While typical current sensing resistors offer a load-life stability of ≥0.5 % through a 1000-hour workload, the VCS1625Z features an improved load-life stability of ±0.02 % at +70 °C for 2000 hours at rated power.
