t520 series ? ko cap ? kemet organic capacitor low esr tantalum chip capacitor with polymer electrode kemet introduces the new t520 series kemet organic - ko - capacitor. the ko cap is a tantalum capac - itor, with ta anode and ta 2 o 5 dielectric. however, a conductive, organic, polymer replaces the mno 2 as the cath - ode plate of the capacitor. the polymer is 100 times more conductive than the mno 2 . this results in very low esr (up to 50% less than equivalent standard ta types) and improved cap retention at high frequency. the ko cap also exhibitis a benign failure mode, which eliminates the ignition failures that can occur in standard tantalum types. removal of the mno 2 eliminates the source of oxygen that can fuel the ignition if the capacitor fails short in a cir - cuit that allows high fault current. the new t520 series captures the best features of multilayer ceramic caps (low esr and high frequency cap retention), aluminum electrolytics (benign failure mode), and proven solid tantalum technology (volumetric effi - ciency, surface mount capability, and no wearout mechanism). the ko cap can reduce component counts, elimi - nate through-hole assembly by replacing cumbersome leaded aluminum capacitors, and offer a more cost effec - tive solution to high-cost high-cap ceramic capacitors. these benefits allow the designer to save both board space and money. case size kemet eia/iecq l w h k 0.20 f 0.1 s 0.3 x(ref) t(ref) a(min) g(ref) e(ref) d 7343 7.3 0.3 4.3 0.3 2.8 0.3 1.5 2.4 1.3 0.10 0.10 0.13 3.8 3.5 3.5 v 7343l 7.3 0.3 4.3 0.3 1.9 0.1 1.1 2.4 1.3 0.05 0.13 3.8 3.5 3.5 dimensions - millimeters new product release t520 ratings & part number reference cap esr m w w ripple current ma rms f case kemet dc leakage df % 120 hz 100khz 25o 100 khz max (20%) size part number a +25oc max + 25oc max max 25oc 85oc 105oc 4 volt rating at +85oc (3.3 volt rating at 105oc) 220 v/7343l t520v227m004as 88.0 10% 45 1657 1491 663 6.3 volt rating at 85oc (5 volt rating at 105oc) 150 d/7343 t520d157m006as 94.5 10% 55 1651 1486 660 150 v/7343l t520v157m006as 94.5 10% 45 1657 1491 662 220 d/7343 t520d227m006as 138.6 10% 50 1732 1559 693 330 d/7343 t520d337m006as 207.9 10% 45 1826 1643 730 10 volt rating at +85oc (8 volt rating at 105oc) 100 d/7343 t520d107m010as 100.0 10% 80 1369 1232 548 150 d/7343 t520d157m010as 150.0 10% 55 1651 1486 660 outline drawings f3233 1/00
