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. 1 of 2 DS9098P REVISION HISTORY REVISION DATE DESCRIPTION PAGES CHANGED Added coplanarity specification of contact tabs to the data sheet (only affects graphic) 022008 Minor formatting adjustments (only affects graphic) 1 Changed “30% glass fiber reinforced Nylon 46” to “glass fiber reinforced liquid crystal polymer” 8/09 Added lead(Pb)-free status to the Ordering Information PART information 1 2/12 Changed the third bullet in the Features from “tin-lead plating” to “100% matte tin plating” for lead(Pb)-free compliance 1 2 of 2 Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product.
