Product News July 22, 2014

Nichicon has added to the LD (ULD) series of extra long-life aluminum electrolytic capacitors with a guaranteed endurance of 20,000 hours at 105°C (160 to 450V, Φ6.311L to Φ1831.5L), which are primarily used in LED lighting and power source adaptors. The new product is rated from 10 to 100V and guaranteed for 10,000 hours at 105°C (Φ511L to Φ811.5L). The series was developed to offer longer life, so by adding these 10 to 100V products to the series we have achieved longer life from low to high voltages.

These products will be exhibited at Power Systems Exhibition 2014 held at Tokyo Big Sight from July 23 to 25 (Wednesday to Friday).

Overview, 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 with low prices; 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, the new rating addition to the LD Series doubles the overall lifespan of the earlier compact HV Series. (At Φ511L, HV Series: 105°C 5,000 hours, LD Series: 105°C 10,000 hours).

The LD series has truly the optimal aluminum electrolytic capacitor lineup for a variety of power sources, especially LED lighting.
