RVCU series high-voltage chip resistors support voltage divider, sensing and measurement circuits requiring stable high-voltage performance. Features voltage coefficient of resistance values from 25ppm–50ppm, lower than conventional high-voltage chip resistors, for improved precision in voltage divider applications. Available in 1206, 2010 and 2512 package sizes with working voltages from 800V–3000V, tolerances to 0.5% and 100ppm TCR. Includes anti-sulfur construction per ASTM-B-905-5 and IEC-62368 compliance for values from 75kΩ–27MΩ. Intended for LED lighting, medical equipment, communications systems, test and measurement instruments and high-voltage control applications.

Tigees released its Free FPC/PCB Engineering Calculators toolkit for engineers developing flexible PCB and rigid-flex designs. The web-based resource includes tools for bend radius screening, controlled-impedance planning, trace width and current estimation, thermal review and signal-integrity evaluation. Supports early layout review, DFM preparation and stackup planning prior to fabrication. Includes calculators for static and dynamic bend radius estimation, copper strain screening and impedance analysis for flexible circuit applications.
