DESCRIPTION
The DS9098P iButton retainer is a low-cost, surface-mount device to secure an F5 iButton on a PCB. It
consists of three metal pieces (two for ground, one for data) molded into a body of black, heat-stabilized,
glass fiber reinforced liquid crystal polymer. 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 and 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 44mm tape. Alignment
pedestals keep the part oriented on tape with the latches adjacent to the sprockets.
