Malvern, Pa.Vishay Intertechnology Inc. has introduced the VCS1625Z ultra-high-precision Z-Foil surface-mount current sensing chip resistor that provides an industrial-grade absolute TCR of ±0.05ppm/°C from 0°C to +60°C and ±0.2ppm/°C from -55°C to +125°C, +25°C ref., a power coefficient of ±5ppm 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, according to Vishay.
The VCS1625Z resistor is built on Vishay's Z- Foil technology, which provides a significant reduction of the resistive component's sensitivity to ambient temperature variations (TCR) and applied power changes (PCR).
Typical applications include precision current sensing, switching and linear power supplies, weigh scales, feedback circuits, precision voltage dividers, power management systems, and amplifiers in test and measurement instrumentation; laboratory, medical, and weapons systems; electron beam applications; satellites and aerospace systems; and commercial and military avionics.
Pricing: For U.S. delivery starts at $4.20.
Availability: Samples and production quantities of the VCS1625Z are available now, with lead times of 72 hours for samples, and three weeks for standard orders.
