DESCRIPTION
The DS9098P iButton Retainer is a low-cost, surface-mount device to secure an F5 iButton on a printed
circuit board. It consists of three metal pieces (two for GROUND, one for DATA) molded into a body of
black, heat-stabilized, 30% glass fiber reinforced Nylon 46.
When inserting an iButton into the DS9098P, closely align axis of the iButton and the retainer. The
retainer then latches the flange of the iButton. At removal, limit deflection of retainer latches to just free
the iButton edge from retained state. Avoid applying excess force to latches.
The DS9098P is only available on tape & reel. The tape specifications match those of 68-lead PLCC
devices except for the deeper pockets and tape-feed sprockets on either side of the 44 mm tape. Align-
ment pedestals keep the part oriented on tape with the latches adjacent to the sprockets.
