Part Number: TLV431A
Other Parts Discussed in Thread: TEST

Hi ,

My customer is using TLV431AIDBZR , so we supplied them in the month of Sept-16 @2500 Nos.

They took part in production and  It is observed that  IC (TLV431A1 shunt regulator IC)  pins having solderability problem. 

Observations: -  1) Components leads have the blackish coating.

                                2) During re flow soldering no wettability exhibits. So difficult for Re flow soldering.
