Sulfur-resistant, AEC-Q200 high-power, thick film chip resistors

New Products |
From Bourns, these high-power resistors offer high pulse load capabilities and enhanced power ratings. The CRMxxxxA and CRSxxxxA are sulfur-resistant and AEC-Q200 compliant suiting them for automotive driver assistant, information, entertainment and lighting applications, as well as commercial, automation, industrial, power supply and stepper-motor drive designs.

Designed to operate in harsh environments where there are elevated levels of sulfur contamination, Bourns’ latest resistor series have been tested in accordance with ASTM B809-9 methods. Made using a thick film element printed onto a ceramic substrate, the resistors offer additional product lifespan benefits compared to standard film resistors when exposed to a sulfurous gas environment.

The chip resistors are available in six different footprints from small 0603 (1608 Metric) up to 2512 (6431 Metric). The Model CRMxxxxA provides a wide resistance range up to 1 megOhms and low resistance values from 0.05 Ohms. This models’ high power rating suits it for current sensing. In addition, the Model CRSxxxxA delivers superior pulse load capabilities for enhanced protection of today’s smaller, more sensitive electronic designs.
