Vishay VCS1625ZUsing Z-Foil technology, Vishay Intertechnology’s VCS1625Z SMT current sensing chip resistor demonstrates an absolute TCR of ±0.05 ppm/°C from 0°C to 60°C and ±0.20 ppm/°C from -55°C to 125°C with a 25°C ref. The device exhibits power coefficient ("?R due to self heating") of ±5 ppm at rated power, a tolerance of ±0.20%, and load-life stability of ±0.020% at 70°C for 2,000 hours at rated power. The resistor offers a 0.500 W power rating at 70°C, current noise of <-40 dB, thermal EMF of 0.05 µV/°C, a non-inductive (<0.08 µH), non-capacitive design, and a 4-Kelvin connection. The component presents a rise time of 1 ns without ringing, ESD withstanding exceeding 25 kV, resistance range from 0.300 O to 10 O, and optimization for EEE-INST-002 and MIL-PRF 55342 screening. Applications include precision current sensing, switching and linear power supplies, weigh scales, feedback circuits, precision voltage dividers, power management systems, amplifiers, electron beam applications, satellites and aerospace systems, and commercial and military avionics. Pricing starts at $4.20.
