The automotive grade, AEC-Q200 compliant CWM-Q Series delivers the enhanced heat dissipation and mechanical stability required in automotive and industrial designs
RIVERSIDE, Calif., September 17, 2025 - Bourns, Inc., a leading manufacturer and supplier of electronic components for power, protection, and sensing solutions, today announced a new line of automotive grade, AEC-Q200 compliant wide terminal thick film resistors. The CWM-Q Series is engineered to support the high power density and robust performance required in many of today’s demanding applications. As automotive and industrial designers increasingly seek higher watt‑per‑area and solder‑joint reliability, Bourns designed its new thick film resistor line with wide terminals that deliver enhanced thermal dissipation and mechanical stability. This makes them particularly well-suited for automotive ECUs, LED lighting modules, power management systems and other heat-sensitive power applications that require high dependability.
The Bourns® CWM-Q Series is available in compact 0612 and 1225 package sizes with power ratings up to 2 W and resistance values ranging from 1 ohm (Ω) to 1 megaohm (MΩ), offering additional flexibility to accommodate various design needs. Constructed with RoHS-compliant* materials and designed for compatibility with standard reflow soldering processes, the CWM-Q Series features a wide operating temperature range from -55 °C to +155 °C. The series has also been tested for endurance under accelerated stress conditions, including thermal cycling, high temperature exposure, moisture resistance and mechanical shock.
The Bourns® CWM-Q Series is available now and is RoHS* compliant and halogen free**. For more detailed product information, please see: bourns.com/products/resistors/thick-film-chip-resistors.
*RoHS Directive 2015/863, Mar 31, 2015 and Annex.
**Bourns considers a product to be "halogen free" if (a) the Bromine (Br) content is 900 ppm or less; (b) the Chlorine (Cl) content is 900 ppm or less; and (c) the total Bromine (Br) and Chlorine (Cl) content is 1500 ppm or less.
