RIVERSIDE, Calif., November 20, 2017 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today released two new series of thick film chip resistors that offer enhanced power ratings up to 2 W at 70 °C. The Bourns® Models CRMxxxxA and CRSxxxxA are sulfur-resistant and AEC-Q200 compliant making them well-suited 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.
Offering broad suitability for a diverse range of applications, the new 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 makes it an ideal solution for current sensing. In addition, the Model CRSxxxxA delivers superior pulse load capabilities for enhanced protection of today’s smaller, more sensitive electronic designs.
Available now, the Bourns® Model CRMxxxA and CRSxxxxA series are RoHS compliant* and halogen free**. As a pricing reference, Model CRM0603AF (1-10 million ohms) is priced at $0.003/pc in 5,000-piece quantities. Model CRM2512AF (1-10 million ohms) is priced at $0.073/pc in 5,000-piece quantities. Model CRS0603A-F is priced at $0.016/pc in 5,000-piece quantities. Model CRS2512A-F is priced at $0.147/pc in 4,000-piece quantities.
