Bourns AEC-Q200 High Power Thick Film Resistors

Bourns CRM-A and CRS-A Sulfur-Resistant, AEC-Q200-Compliant Thick Film Chip Resistors are designed to operate in harsh environments exposed to higher levels of sulfur contamination. Bourns CRM-A and CRS-A  resistors are high-power resistors available in six different footprints from a small, 0603 (1608 Metric) package up to a 2512 (6431 Metric) package. The CRM-A series has a wide resistance range from 0.05Ωs and a high power rating, making it ideal for current sensing. The CRS-A devices have superior pulse load capability. The resistors are made using a thick film element which is printed onto a ceramic substrate and tested in accordance with ASTM B809-9 method. The components have a wide resistance range. The Bourns resistors are suitable for use in applications such as automotive (driver assistant, information, entertainment, and lighting applications), industrial, automation, power supplies, and communication base stations.
