Reg.one batch shipment of EL3053S(TA)-V EVERLIGHT, from the X-ray, we did find the internal structure is different between different date code.
Actually we can see 3 different structures (even from the same Lot), as below.
with 3 round bond wires
with 3 square bond wires
with 4 square bond wires
Is above three different structures all normal?
Thank you.
If you purchased the product from DigiKey and encountered such problems after receiving the goods, you can contact the salesperson who handled your purchase for further handling.
You may provide related pictures. As you said it is the internal structure. It is hard to tell. If you can point out the differences between the product and the parameters in the datasheet, such as dimensions, electrical performance, etc. It will be better.
