NUD4700 是一款电子分路,在一个 LED 进入开路状态时提供旁通电流。LED 在遇到瞬变和电涌情况时,本身就具有相当脆弱的特性。还有很多情况下必须保持 LED 照明的高度可靠性,如头灯、灯塔、桥梁、飞机、跑道等。此类情况下,增加低成本的 NUD4700 即可全面保证整个 LED 串不会在一个 LED 发生故障时全部熄灭。NUD4700 还适用于需要电路连续性的其他负载。此器件适用于 1W LED(标称 350mA @ 3V)。

Re-calculate Data
Data is based on the following assumptions.
Note: The temperature and confidence level may be adjusted to your requirements.
Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
