Part Number: TPS54040A For this part, the leads of the parts were found as discoloration, seems like oxidation as attached photo.
We saw that lead finish is copper, is that normal? And is that still good to use?
Thanks,
Brian

Hi,
Currently, we're using the TPS54040A on a downhole device and supplies around 100mA. With this current rating, can TPS54040A function without failure after 3-6 months of continuous operation?
Also, are…
