Bourns Announces New Sulfur-Resistant Fixed Resistor Series

RIVERSIDE, Calif., June 24, 2019 - Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced a new sulfur-resistant AEC-Q200 compliant thick film resistor family. The Bourns® Model CRxxxxA-AS chip resistor series is offered in eight different footprints from small 0201 (0603 metric) to 2512 (6432 metric) with rated power from 0.05 to 1 watt. The new surface-mount chip resistors also feature a wide resistance range from 1 ohm to 20 megohms making them ideal for a variety of general-purpose applications.

Bourns designed these resistors to operate in certain harsh environments with higher levels of sulfur contamination. They are manufactured using a thick film element printed onto a ceramic substrate, and tested in accordance with ASTM B809-95 methods, which tests for the porosity of metallic coatings exposed to humid sulfur vapor.

Available now, the Model CRxxxxA-AS chip resistor series complements the other circuit conditioning components from Bourns that include power inductors and rectifier diodes. Bourns' expanded line of sulfur-resistant fixed resistors are RoHS* compliant and halogen free**. For additional product information, please see the datasheet on the Bourns website: www.bourns.com/docs/product-datasheets/crxxxxa-as.pdf.

*RoHS Directive 2015/863, Mar 31, 2015 and Annex.
