    Hi KPK,

    Thanks for your question!

    Of the current orderable devices, none of them have the formed lead options.

    Please see some more convention information below:

    NOPB = Straight lead bulk pack

    If tape & reel = Formed lead only

    M = Magazine pack, formed lead

    LFT = National body dimensions (slightly larger) + eutectic die attach

    I hope this helps!

    Best Regards,

    Andrew Li

    hi Andrew,

    Does that means i can only find: LM431AIZ/LFT1, LM431ACZ/LFT3 or LM431ACZ/LFT4 in formed lead package? 

    LM431C do not have formed lead option, is that correct?

    Best Regards,
    Felix

    Hi Felix,

    That is correct. Since the LM431AIZ/LFT1, LM431ACZ/LFT3 and LM431ACZ/LFT4 are in tape & reel, they are formed lead package. Please keep in mind the LFT signals the National body dimensions.

    Any ordering option with tape & reel comes with formed lead only, and orderable part numbers ending in /NOPB (may come in bulk pack, tube, etc) will have straight leads.

    Unfortunately, LM431C does not have formed lead option available.

    Best Regards,

    Andrew Li
