The element is comprised of an anode<br \/>\nfoil, paper separators saturated with electrolyte and a cathode<br \/>\nfoil. The foils are high-purity aluminum and are etched to increase<br \/>\nthe surface area in contact with the electrolyte.<\/p>\n<p>While it may appear that the capacitance is between the two<br \/>\nfoils, actually the capacitance is between the anode foil and the<br \/>\nelectrolyte. The positive plate is the anode foil; the dielectric<br \/>\nis the insulating aluminum oxide on the anode foil; the true<br \/>\nnegative plate is the conductive, liquid electrolyte, and the<br \/>\ncathode foil merely connects to the electrolyte.<\/p>\n<p>This construction delivers colossal capacitance because etching<br \/>\nthe foils can increase surface area more than 100 times and the<br \/>\naluminum-oxide dielectric is less than a micrometer thick. Thus the<br \/>\nresulting capacitor has very large plate area and the plates are<br \/>\nawfully close together.<\/p>\n<p>These capacitors routinely offer capacitance values from 0.1 \u00b5F<br \/>\nto 3 F and voltage ratings from 5 V to 500 V. They are polar<br \/>\ndevices, having distinct positive and negative terminals, and are<br \/>\noffered in an enormous variety of styles which include molded and<br \/>\ncan-style SMT devices, axial- and radial-leaded can styles, snap-in<br \/>\nterminals styles and large-can, screw-terminal styles.<br \/>\nRepresentative capacitance-voltage combinations include:<\/p>\n<p>a) 330 \u00b5F at 100 V, 1000 \u00b5F at 50 V and 6800 \u00b5F at 10 V for SMT<br \/>\ndevices;<\/p>\n<p>b) 100 \u00b5F at 450 V, 6,800 \u00b5F at 50 V and 10,000 \u00b5F at 10 V for<br \/>\nminiature-can styles;<\/p>\n<p>c) 1200 \u00b5F at 450 V and 39,000 \u00b5F at 50 V for snap-in can<br \/>\nstyles;<\/p>\n<p>d) 9000 \u00b5F at 450 V and 390,000 \u00b5F at 50 V for large-can<br \/>\nscrew-terminal styles.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Aluminum-Electrolytic Capacitor Application Guideline<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/ecia\/\"><b>ECIA<\/b><\/a><\/td>\n<td>2014<\/td>\n<td>38<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":556925,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2649],"product_tag":[],"class_list":{"0":"post-556917","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-ecia","8":"first","9":"instock","10":"sold-individually","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/556917","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/556925"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=556917"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=556917"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=556917"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
