The British standard BS 1852〔(BS 1852:1975, IEC 60062:1974 )〕 and its replacement, BS EN 60062,〔(BS EN 60062:1994 )〕〔(BS EN 60062:2005 )〕 comprises a colour code for fixed resistors; letter and digit code for resistance (R for ohms, K for kilohms and M for megohms) and capacitance values. ==Codes== Letter code for resistance and capacitance tolerances and a date code for capacitors and resistors: coding: :BB - 1/8 WATTS, :CB - 1/4 ″ , :EB - 1/2 ″ , :GB - 1/1 ″ , :5 - ±5% tolerance, :2 - ±20% ″, :1 - ±10% ″, Steps to find out the resistance or capacitance values: # 1st 2 letters gives the power dissipation capacity. # next 3 digits gives the resistance value. ## 1st 2 digits are the significant values ## 3rd digit is the multiplier. # final digit gives the tolerance. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「BS 1852」の詳細全文を読む スポンサード リンク
