[Cornell Dubilier / Illinois Capacitor](https://www.digikey.com/en/supplier-centers/cornell-dubilier-electronics) uses the suffix SD for a packging suffix on some of their capacitors. A good example to show this is part number [105TTA050MSD](https://www.digikey.com/en/products/detail/cornell-dubilier-illinois-capacitor/105TTA050MSD/5964378) The SD suffix indicated “Standard” reeling per the [special order options linked](https://www.cde.com/resources/catalogs/Order-Options/Axial_Lytic_TapeReel.pdf) on the [datasheet](https://www.cde.com/resources/catalogs/TTA.pdf). Also note the additional optional packaging suffix, C1, C2, and C3 from the special order link. > **Relevant Parts** > > | | | | > | --- | --- | --- | > | DK Part # | Mfr Part # | Description | > | 1572-1249-2-ND,1572-1249-1-ND | 476TTA016MSD | CAP ALUM 47UF 20% 16V AXIAL | > | 1572-1035-2-ND,1572-1035-1-ND | 106TTA035MSD | CAP ALUM 10UF 20% 35V AXIAL | > | 1572-1246-2-ND,1572-1246-1-ND | 105TTA050MSD | CAP ALUM 1UF 20% 50V AXIAL | > | 1572-1247-2-ND,1572-1247-1-ND | 106TTA050MSD | CAP ALUM 10UF 20% 50V AXIAL | > | 1572-1248-2-ND,1572-1248-1-ND | 226TTA035MSD | CAP ALUM 22UF 20% 35V AXIAL | Resource: [Special Order Taping Specs](https://www.cde.com/resources/catalogs/Order-Options/Axial_Lytic_TapeReel.pdf) Datasheet: [TTA.pdf (cde.com)](https://www.cde.com/resources/catalogs/TTA.pdf)
