CR-A Sulfur-Resistant Chip Resistors

Bourns CR-A Sulfur-Resistant Chip Resistors are available in eight different footprints from small 0201 (0603 metric) to 2512 (6432 metric). These AEC-Q200-compliant resistors offer rated power from 0.05W to 1W and feature a wide resistance range from 1Ω to 20MΩ. Bourns CR-A resistors are made using a thick-film element printed onto a ceramic substrate. These resistors are designed to operate in harsh environments exposed to high levels of sulfur contamination.
