This document introduces the features and characteristics of Vishay Techno's CRHV series of high voltage chip resistors, including resistance range, resistance tolerance, temperature coefficient, voltage rating, short time overload characteristics, external dimensions, packaging materials, working temperature range, and service life.
The 4CRHV series are high‑voltage chip resistors designed for applications up to 3000 V. They offer outstanding stability (< 0.5 %), flow‑solderability, automatic placement capability, and a variety of termination styles and packaging options.
Key specifications include a resistance range of 2 MΩ‑50 GΩ, voltage rating of 1500‑3000 V, temperature coefficient of ± 100 ppm/°C, and an operating temperature range of –55 °C to +150 °C. The devices are built on a 96 % alumina substrate with proprietary cermet elements and are available in multiple termination styles (A, B, C) and packaging formats.
