精密电阻阻值表2012-02-13 13:12:39|分类：硬件基础|举报|字号订阅精密贴片电阻是用代码来计算的，如01C就是10K。下面是代码，就像查字典一样。又例如：10欧的电阻用代码01X表示，仔细看下表你就会明白的。一点没有数字标注的直观方便，下面就是阻值表，以备自己查验：标准阻值表 E-960603F(+1%) Standard Resistance Table标准阻值表1E-96阻值代码阻值代码阻值代码阻值代码阻值代码阻值代码1001X10001A1.00K01B10.0K01C100K01D1M01E10.202X10202A1.02K02B10.2K02C102K02D10.503X10503A1.05K03B10.5K03C105K03D10.704X10704A1.07K04B10.7K04C107K04D1105X11005A1.10K05B11.0K05C110K05D11.306X11306A1.13K06B11.3K06C113K06D11.507X11507A1.15K07B11.5K07C115K07D11.808X11808A1.18K08B11.8K08C118K08D12.109X12109A1.21K09B12.1K09C121K09D12.410X12410A1.24K10B12.4K10C124K10D12.711X12711A1.27K11B12.7K11C127K11D1312X13012A1.30K12B13.0K12C130K12D13.313X13313A1.33K13B13.3K13C133K13D13.714X13714A1.37K14B13.7K14C137K14D1415X14015A1.40K15B14.0K15C140K15D14.316X14316A1.43K16B14.3K16C143K16D14.717X14717A1.47K17B14.7K17C147K17D1518X15018A1.50K18B15.0K18C150K18D15.419X15419A1.54K19B15.4K19C154K19D15.820X15820A1.58K20B15.8K20C158K20D16.221X16221A1.62K21B16.2K21C162K21D16.522X16522A1.65K22B16.5K22C165K22D16.923X16923A1.69K23B16.9K23C169K23D17.424X17424A1.74K24B17.4K24C174K24D17.825X17825A1.78K25B17.8K25C178K25D18.226X18226A1.82K26B18.2K26C182K26D18.727X18727A1.87K27B18.7K27C187K27D19.128X19128A1.91K28B19.1K28C191K28D19.629X19629A1.96K29B19.6K29C196K29D2030X20030A2.00K30B20.0K30C200K30D20.531X20531A2.05K31B20.5K31C205K31D2132X21032A2.10K32B21.0K32C210K32D21.533X21533A2.15K33B21.5K33C215K33D22.134X22134A2.21K34B22.1K34C221K34D22.635X22635A2.26K35B22.6K35C226K35D23.236X23236A2.32K36B23.2K36C232K36D23.737X23737A2.37K37B23.7K37C237K37D24.338X24338A2.43K38B24.3K38C243K38D24.939X24939A2.49K39B24.9K39C249K39D25.540X25540A2.55K40B25.5K40C255K40D26.141X26141A2.61K41B26.1K41C261K41D26.742X26742A2.67K42B26.7K42C267K42D27.443X27443A2.74K43B27.4K43C274K43D2844X28044A2.80K44B28.0K44C280K44D28.745X28745A2.87K45B28.7K45C287K45D29.446X29446A2.94K46B29.4K46C294K46D30.147X30147A3.01K47B30.1K47C301K47D30.948X30948A3.09K48B30.9K48C309K48D标准阻值表2E-96阻值代码阻值代码阻值代码阻值代码阻值代码31.649X31649A3.16K49B31.6K49C316K49D32.450X32450A3.24K50B32.4K50C324K50D33.251X33251A3.32K51B33.2K51C332K51D3452X34052A3.40K52B34.0K52C340K52D34.853X34853A3.48K53B34.8K53C348K53D35.754X35754A3.57K54B35.7K54C357K54D36.555X36555A3.65K55B36.5K55C365K55D37.456X37456A3.74K56B37.4K56C374K56D38.357X38357A3.83K57B38.3K57C383K57D39.258X39258A3.92K58B39.2K58C392K58D40.259X40259A4.02K59B40.2K59C402K59D41.260X41260A4.12K60B41.2K60C412K60D42.261X42261A4.22K61B42.2K61C422K61D43.262X43262A4.32K62B43.2K62C432K62D44.263X44263A4.42K63B44.2K63C442K63D45.364X45364A4.53K64B45.3K64C453K64D46.465X46465A4.64K65B46.4K65C464K65D47.566X47566A4.75K66B47.5K66C475K66D48.767X48767A4.87K67B48.7K67C487K67D49.968X49968A4.99K68B49.9K68C499K68D51.169X51169A5.11K69B51.1K69C511K69D51.370X52370A5.23K70B52.3K70C523K70D53.671X53671A5.36K71B53.6K71C536K71D54.972X54972A5.49K72B54.9K72C549K72D56.273X56273A5.62K73B56.2K73C562K73D57.674X57674A5.76K74B57.6K74C576K74D5975X59075A5.90K75B59.0K75C590K75D60.476X60476A6.04K76B60.4K76C604K76D61.977X61977A6.19K77B61.9K77C619K77D63.478X63478A6.34K78B63.4K78C634K78D64.979X64979A6.49K79B64.9K79C649K79D66.580X66580A6.65K80B66.5K80C665K80D68.181X68181A6.81K81B68.1K81C681K81D69.882X69882A6.98K82B69.8K82C698K82D71.583X71583A7.15K83B71.5K83C715K83D73.284X73284A7.32K84B73.2K84C732K84D7585X75085A7.50K85B75.0K85C750K85D76.886X76886A7.68K86B76.8K86C768K86D78.787X78787A7.87K87B78.7K87C787K87D80.688X80688A8.06K88B80.6K88C806K88D82.589X82589A8.25K89B82.5K89C825K89D84.590X84590A8.45K90B84.5K90C845K90D86.691X86691A8.66K91B86.6K91C866K91D88.792X88792A8.87K92B88.7K92C887K92D90.993X90893A9.09K93B90.9K93C909K93D93.194X93194A9.31K94B93.1K94C931K94D95.395X95395A9.53K95B95.3K95C953K95D97.696X97696A9.76K96B97.6K96C976K96DPS:贴片电阻阻值标注方法1E-24标注方法9 ? l2 A5 H+ q1 a4 YE-24标注法有两位有效数字，精度在2%（-G），5%（-J），10%（-K）（1） 常用电阻标注XXY XX代表底数，Y代表指数例如470 = 47: f# q7 Q, BO0 e0 mMF r103 = 10k224 = 220k（2） 小于10欧姆的电阻的标注) V) I* ?.
