电阻精度与常用阻值.doc

电阻精度与常用阻值日期：2005-4-23来源：侃单片机 作者：sirliu字体：大 中 小 国家标准规定了电阻的阻值按其精度分为两大系列，分别为E-24系列和E-96系列，E-24系列精度为5%，E-96系列为1%， 在这两种系列之外的电阻为非标电阻，较难采购。下面列出了常用的5和1精度电阻的标称值，供大家设计时参考。 精度为5的碳膜电阻，以欧姆为单位的标称值： 1.05.6331608203.9K20K100K510K2.7M 1.16.2361809104.3K22K110K560K3M 1.26.8392001K4.7K24K120K620K3.3M 1.37.5432201.1K5.1K27K130K680K3.6M 1.58.2472401.2K5.6K30K150K750K3.9M 1.69.1512701.3K6.2K33K160K820K4.3M 1.810563001.5K6.6K36K180K910K4.7M 2.011623301.6K7.5K39K200K1M5.1M 2.212683601.8K8.2K43K220K1.1M5.6M 2.413753902K9.1K47K240K1.2M6.2M 2.715824302.2K10K51K270K1.3M6.8M 3.016914702.4K11K56K300K1.5M7.5M 3.3181005102.7K12K62K330K1.6M8.2M 3.6201105603K13K68K360K1.8M9.1M 3.9221206203.2K15K75K390K2M10M 4.3241306803.3K16K82K430K2.2M15M 4.7271507503.6K18K91K470K2.4M22M 5.130 精度为1的金属膜电阻，以欧姆为单位的标称值： 10331003321K3.32K10.5K34K107K357K 10.233.21023401.02K3.4K10.7K34.8K110K360K 10.5341053481.05K3.48K11K35.7K113K365K 10.734.81073501.07K3.57K11.3K36K115K374K 1135.71103571.1K3.6K11.5K36.5K118K383K 11.3361133601.13K3.65K11.8K37.4K120K390K 11.536.51153651.15K3.74K12K38.3K121K392K 11.837.41183741.18K3.83K12.1K39K124K402K 1238.31203831.2K3.9K12.4K39.2K127K412K 12.1391213901.21K3.92K12.7K40.2K130K422K 12.439.21243921.24K4.02K13K41.2K133K430K 12.740.21274021.27K4.12K13.3K42.2K137K432K 1341.21304121.3K4.22K13.7K43K140K442K 13.342.21334221.33K4.32K14K43.2K143K453K 13.7431374301.37K4.42K14.3K44.2K147K464K 1443.21404321.4K4.53K14.7K45.3K150K470K 14.344.21434421.43K4.64K15K46.4K154K475K 14.745.31474531.47K4.7K15.4K47K158K487K 1546.41504641.5K4.75K15.8K47.5K160K499K 15.4471544701.54K4.87K16K48.7K162K511K 15.847.51584751.58K4.99K16.2K49.9K165K523K 1648.71604871.6K5.1K16.5K51K169K536K 16.249.91624991.62K5.11K16.9K51.1K174K549K 16.5511655101.65K5.23K17.4K52.3K178K560K 16.951.11695111.69K5.36K17.8K53.6K180K562K 17.452.31745231.74K5.49K18K54.9K182K576K 17.853.61785361.78K5.6K18.2K56K187K590K 1854.91805491.8K5.62K18.7K56.2K191K604K 18.2561825601.82K5.76K19.1K57.6K196K619K 18.756.21875621.87K5.9K19.6K59K200K620K 19.157.61915651.91K6.04K20K60.4K205K634K 19.6591965781.96K6.19K20.5K61.9K210K649K 2060.42005902K6.2K21K62K215K665K 20.561.92056042.05K6.34K21.5K63.4K220K680K 21622106192.1K6.49K22K64.9K221K681K 21.563.42156202.15K6.65K22.1K66.5K226K698K 2264.92206342.2K6.8K22.6K68K232K715K 22.166.52216492.21K6.81K23.2K68.1K237K732K 22.6682266652.26K6.98K23.7K69.8K240K750K 23.268.12326802.32K7.15K24K71.5K243K768K 23.769.82376812.377.32K24.3K73.2K249K787K 2471.52406982.4K7.5K24.9K75K255K806K 24.373.22437152.43K7.68K25.5K76.8K261K820K 24.7752497322.49K7.87K26.1K78.7K267K825K 24.975.52557502.55K8.06K26.7K80.6K270K845K 25.576.82617682.61K8.2K27K82K274K866K 26.178.72677872.67K8.25K27.4K82.5K280K887K 26.780.62708062.7K8.45K28K84.5K287K909K 27822748202.74K8.66K28.7K86.6K294K910K 27.482.52808252.8K8.8K29.4K88.7K300K931K 2884.52878452.87K8.87K30K90.9K301K953K 28.786.62948662.94K9.09K30.1K91K309K976K 29.488.73008873.0K9.1K30.9K93.1K316K1.0M 3090.93019093.01K9.31K31.6K95.3K324K1.5M 30.1913099103.09K9.53K32.4K97.6K330K2.2M 30.993.13169313.16K9.76K33K100K332K 31.695.33249533.24K10K33.2K102K340K 32.497.63309763.3K10.2K33.6K105K348K 电阻阻值标称E24E48E96E192E48E96E192E48E96E192E48E96E192E48E96E1921.01001001001621621622612612614224224226816816811.11011642644276901.2102 1021651652672674324326986981.3104167 271 437 7061.51051051051691691692742742744424424427157157151.6106 172 277 448 7231.8107 107 174 174 280 280 453 453 732 7322.0109 176 284 459 7412.2110 110 110 178178 178287 287 287 464 464 464 750 750 7502.4111 180 291 470 7592.7113 113 182 182 294 294 475 475 768 7683.0114 184 298 481 7773.3115 115 115 187 187 187 301 301 301 487 487 487 787 787 7873.6117 189 305 493 7963.9118 118 191 191 309 309 499 499 806 8064.3120 193 312 505 8164.7121 121121196 196196316 316316511 511511825 825 8255.1123 198 320 517 8355.6124 124 200 200 324 324 523 523 845 8456.2126 203 328 5308566.8127 127127205 205205332 332332536 536 536 866 866 8667.5129 208 336 542 8768.2130 130 210 210 340 340 549 549 887 8879.1132 213 344 556 898133 133133215 215215348 348348562 562562909 909 909135 218 352 569 920137 137 221 221 357 357 576 576 931 931138 223 361 583 942140 140140226 226 226 365365365590590590953 953953142229370597965143 143 232 232 374 374 604 604 976
