SELLER SELLS NEW PARTS!!! I purchased a 2nd time.Beware other sellers on Ali sell the same but they are not new, salvaged from equipment and you dont know how long they will work for because of thermal stress over time,. If they work well at all
Good seller.Sent new items, other sellers send used from salvage equipment. Tested parameters C3855, hFE 144, uf 587mv. 1491 hFE 184, uf 561mv. Will buy again from this seller
