Overview
TheKEMETOrganicCapacitor(KO-CAP)isasolid
electrolyticcapacitorwithaconductivepolymercathode
capableofdeliveringverylowESRandimproved
capacitanceretentionathighfrequencies.KO-CAP
combinesthelowESRofmultilayerceramic,thehigh
capacitanceofaluminumelectrolyticandthevolumetric
eciencyoftantalumintoasinglesurfacemountpackage.
Unlikeliquidelectrolyte-basedcapacitors,KO-CAP
hasaverylongoperationallifeandhighripplecurrent
capabilities.
TheT591/T598HighHumidity/HighTemperature

Density Level A: For low-density product applications. Recommended for wave solder applications and provides a wider process window for reow
solder processes.
Density Level B: For products with a moderate level of component density. Provides a robust solder attachment condition for reow solder processes.
Density Level C: For high component desity product applications. Before adapting the minimum land pattern variations the user should perform
qualication testing based on the conditions outlined in IPC standard 7351 (IPC–7351).
1 Height of these chips may create problems in wave soldering.
2 Land pattern geometry is too small for silkscreen outline.

1. The embossment hole location shall be measured from the sprocket hole controlling the location of the embossment. Dimensions of embossment
location and hole location shall be applied independent of each other.
2. The tape, with or without components, shall pass around R without damage (see Figure 4).
3. If S1 < 1.0 mm, there may not be enough area for cover tape to be properly applied (see EIA Standard 481–D, paragraph 4.3, section b).
4. B1 dimension is a reference dimension for tape feeder clearance only.
5. The cavity de ned by A0, B0 and K0 shall surround the component with suffi cient clearance that:
(a) the component does not protrude above the top surface of the carrier tape.
(b) the component can be removed from the cavity in a vertical direction without mechanical restriction, after the top cover tape has been removed.
(c) rotation of the component is limited to 20° maximum for 8 and 12 mm tapes and 10° maximum for 16 mm tapes (see Figure 2).
(d) lateral movement of the component is restricted to 0.5 mm maximum for 8 mm and 12 mm wide tape and to 1.0 mm maximum for 16 mm tape (see
Figure 3).
(e) see Addendum in EIA Standard 481–D for standards relating to more precise taping requirements.
