NICHICON has just developed the EJ Series of DC-filtering cylindrical film capacitors, mainly for use in the automotive, industrial equipment and environmental sectors.
The EJ Series will be on display at the CEATEC JAPAN 2014 exhibition to be held at Makuhari Messe October 7–11 (Tuesday–Saturday).
Overview, Background of Development
NICHICON developed this series to meet the market need for DC-filtering/smoothing capacitors which offer higher performance (smaller, capable of performing in low-temperature as well as hot and humid environments, etc.) in the growing automotive, industrial and environmental sectors.
Main Features
By developing an even thinner vapor-deposited film and improving the component storage efficiency, NICHICON has achieved a 40% reduction in size compared to its earlier EU Series product. In addition, the use of resin-molded case-less construction makes this capacitor capable of performing in both low-temperature (-40°C) and high-temperature/high-humidity (85°C, 85% RH, 1000h) environments.
Safety is also enhanced with the adoption of a safety mechanism in the vapor-deposited film, which also increases the lifespan of the product. Finally, this product is composed of environmentally friendly materials.
| 1. | Compact (40% smaller than NICHICON’s previous comparable product) |
|---|---|
| 2. | Performs in both low-temperature (-40°C) and high-temperature/high-humidity (85°C, 85% RH, 1000h) environments |
| 3. | Resin-mold type with safety mechanism |
| 4. | Maintenance-free (long life, high reliability) |
| 5. | Environmentally friendly (RoHS Directive compliant, oil-less) |
