Nichicon has developed the LD series of extra long-life aluminum electrolytic capacitors with a guaranteed endurance of 20,000 hours at 105℃ These capacitors are primarily for use in LED lighting. The LD series lineup will be on display at the CEATEC JAPAN 2013 exhibition, held at Makuhari Messe, October 1-5 (Tues-Sat).

Background of Development

The use of LED lighting has gained widespread popularity in recent years due to its energy conserving properties. LED lighting has two primary advantages: its ability to conserve energy and its ability to maintain a long lifespan. Therefore, the components used in LED lighting must also be capable of holding up under long periods of use. Compared with other types of capacitors, aluminum electrolytic capacitors are relatively compact and have high capacitance; however, they tend to have a more limited lifespan which can negatively affect the life of LED equipment. Due to this demand for longer-lasting aluminum electrolytic capacitors, Nichicon developed the LD series of extra long-life aluminum electrolytic capacitors.

Main Features

By optimizing assembly and product design, Nichicon has achieved similar specifications to their previous long-life CY series but doubled its overall lifespan. ( φ10 × 16L: 10,000 hours/105℃ for the CY; 20,000 hours/105 ℃ for the LD) The LD series truly is the optimal aluminum electrolytic capacitor lineup for a variety of power sources, especially LED lighting.
