2 posts / 0 new

Hi, 

 

Does anyone know if there a FIT or MTBF data available for the LNK454 or any of the LinkSwitch-PL series.

I am working a quick design for a military lighting app. driving a 2.15 watt load.

 

 

Thanks in advance for any help,

Tony

 

The failure rate for the LinkSwitch-PL family of products is 11.068 FITs (MTBF = 90,346,000 hours). This failure rate was estimated by de-rating the high temperature reliability test data to an application use junction temperatureof 55C using an activation energy of 0.7eV and was calculated with a 60% confidence level.
