High Voltage Chip Resistor from Stackpole Supports AI and EV charging
Emerging applications such as AI power infrastructure and EV charging electronics are pushing operating voltages well beyond the limits of legacy designs. While conventional chip resistors are typically constrained to a few hundred volts, today’s power architectures routinely demand continuous operation at 400 V, 800 V, and higher — placing new requirements on component selection, reliability, and layout efficiency.

Stackpole says its RVCA Series is a thick-film, high-voltage chip resistor family purpose-built to meet these elevated demands. Designed to simplify high-voltage circuit implementation, RVCA provides engineers with a reliable, compact solution that reduces the need for series stacking while improving long-term stability. The series is automotive grade, AEC-Q200 qualified, and anti-sulfur compliant per EIA-977, ensuring robust performance in harsh, high-stress environments common to EV, industrial, and power electronics applications.

The RVCA Series supports voltage ratings up to 3 kV in the 2512 case size, with 0805 and larger packages offering minimum ratings of 400 V. This wide voltage capability allows engineers to achieve higher voltage margins with fewer components, simplifying designs and improving system reliability. An exceptionally broad resistance range from 30 kΩ to 100 MΩ further enables efficient implementation of voltage dividers, sensing networks, bleed circuits, and high-impedance nodes across high-voltage platforms.

The company says RVCA resistors are validated through rigorous industry-standard reliability testing, including load life, biased humidity, short-time overload, and temperature cycling. The result is a high-confidence solution that combines elevated voltage capability, design flexibility, and proven reliability—making the RVCA Series a strong choice for next-generation high-voltage designs.
