Nichicon has added a 50V-rated range to the CX series lineup of chip-type aluminum electrolytic capacitors for automotive use, which are guaranteed to 135℃ with -40℃ ESR.*1 Nichicon has also expanded the lineup by adding a larger φ12.5-18mm product. The lineup will be on display at the CEATEC JAPAN 2013 exhibition, held at Makuhari Messe, October 1-5 (Tue.-Sat.).

Background of Development

There has been a trend towards moving ECUs*2 and other automotive control units to the engine compartment in order to provide more space for the car´s passengers. There is also demand for more compactness and higher efficiency. The engine environment can be very stressful on components so they must be able to withstand high temperatures, have a long lifespan, and handle high ripple current. We developed the CX series to meet these demands.
Nichicon has expanded the lineup by adding a 50V product that offers the greater withstand voltage necessary to achieve higher capacity, as well as adding a larger φ12.5/18mm 1product.

Main Features

This product was developed using technology Nichicon has accumulated over half a century. Using a new separator and newly-developed low-evaporation electrolyte, we have optimized the parts and achieved a low-temp ESR category spec product with a high-upper-limit temperature range of 125-135 ℃.
CX series capacitors are also constructed to withstand the heavy vibration conditions found in engine compartments
