In the same way as wire ended components, precision resistors (1% or better) may be marked with a four digit code.\u000bThe first two (or 3) digits are the first two (or 3) digits of the resistance in ohms, and the third(or 4th) is the number of zeros to follow - the 'multiplier'.\u000bResistances of less than 10 ohms have a 'R' to indicate the position of the decimal point.\nSome examples will meake this clearer:\nThree Digit Examples\nFour Digit Examples\n330 is 33 ohms - not 330 ohms\n1000 is 100 ohms - not 1000 ohms\n221 is 220 ohms\n4992 is 49 900 ohms, or 49.9 kohm\n683 is 68 000 ohms, or 68 kohm\n16234 is 162 000 ohms, or 162 kohm\n105 is 1 000 000 ohms, or 1 Mohm\n0R56 or R56 is 0.56 ohms\n8R2 is 8.2 ohms\nBut just to make life more interesting, a new coding system has appeared on 1% types. This is known as the EIA-96 marking method. It consists of a three-character code. The first two digits signify the 3 significant digits of the resistor value, using the lookup table below. The third character - a letter - signifies the multiplier.\ncode\nvalue\ncode\nvalue\ncode\nvalue\ncode\nvalue\ncode\nvalue\ncode\nvalue\n01\n100\n17\n147\n33\n215\n49\n316\n65\n464\n81\n681\n02\n102\n18\n150\n34\n221\n50\n324\n66\n475\n82\n698\n03\n105\n19\n154\n35\n226\n51\n332\n67\n487\n83\n715\n04\n107\n20\n158\n36\n232\n52\n340\n68\n499\n84\n732\n05\n110\n21\n162\n37\n237\n53\n348\n69\n511\n85\n750\n06\n113\n22\n165\n38\n243\n54\n357\n70\n523\n86\n768\n07\n115\n23\n169\n39\n249\n55\n365\n71\n536\n87\n787\n08\n118\n24\n174\n40\n255\n56\n374\n72\n549\n88\n806\n09\n121\n25\n178\n41\n261\n57\n383\n73\n562\n89\n825\n10\n124\n26\n182\n42\n267\n58\n392\n74\n576\n90\n845\n11\n127\n27\n187\n43\n274\n59\n402\n75\n590\n91\n866\n12\n130\n28\n191\n44\n280\n60\n412\n76\n604\n92\n887\n13\n133\n29\n196\n45\n287\n61\n422\n77\n619\n93\n909\n14\n137\n30\n200\n46\n294\n62\n432\n78\n634\n94\n931\n15\n140\n31\n205\n47\n301\n63\n442\n79\n649\n95\n953\n16\n143\n32\n210\n48\n309\n64\n453\n80\n665\n96\n976\nThe multiplier letters are as follows:\nletter\nmult\nletter\nmult\nF\n100000\nB\n10\nE\n10000\nA\n1\nD\n1000\nX or S\n0.1\nC\n100\nY or R\n0.01\n22A is a 165 ohm resistor, 68C is a 49900 ohm (49.9 k) and 43E a 2740000 (2.74 M).
