　　许多刚进行电路设计的人员会在设计电路中将电阻任意取值，这会导致该电阻无法购买到，实际上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
