Thick film chip resistors

Bourns, Inc.’s (Riverside, CA) two new series of thick film chip resistors offer enhanced power ratings up to 2 W at 70°C (158°F). The Bourns Models CRMxxxxA and CRSxxxxA are sulfur-resistant and AEC-Q200 compliant, making them suitable for automotive driver assistant, information, entertainment and lighting applications, as well as commercial, automation, industrial, power supply and stepper-motor drive designs. Available in six different footprints, Bourns’ latest resistor series are designed to operate in harsh environments where there are elevated levels of sulfur contamination. In addition, the resistors have been tested in accordance with ASTM B809-9 methods. Made using a thick-film element printed onto a ceramic substrate, Bourns says the resistors offer additional product lifespan benefits compared to standard film resistors when exposed to a sulfurous gas environment.
