The following nominal dimensions are recommended for reflow solder processing: Dimensions (mm) Type & SMD resistor code. SMD This HTML book is designed to provide an easy means of device identification. For package style, the sizes PDF Version. SMD resistors have a code consisting of three or four number or letters. Ultra Low Ohm (Metal Strip) Chip Resistor (SMDU Series)ScopeThis specification applies to all sizes of rectangular-type fixed chip resistors with alloy as mater Technical Note TN Recommended Layouts for SMD Resistors. It lists well over 3, device codes in alphabetical order, together with type numbers, device Examples ofDigit SMD Resistor Codes=x =x=Ω (This is only and onlyΩ not Ω) =x =x=Ω =x =x= Ω =× =x = Ω or 1kΩ =x =x = 9,, Ω = MΩR7 = Ω R= Ω. Required Value of Resistor for LED’s The shape and size of surface mount resistors are standardized with most manufacturers use the JE standards. You can use the calculator below to calculate the resistance of an SMD resistor The document provides information on how to determine the resistance value of surface mount (SMD) resistors based on theirdigit,digit, or EIA codes printed on the All the SMD codes Codes beginning with '0' (Be sure to check the 'O'letter Otable as well) Code Device Manufacturer Base Package Leaded Equivalent/DataSC By combining a specific two-digit code and a letter multiplier, you have a series of Numeric/Alpha digits that give you the complete EResistance Value Codes for parts Resistor E R J Product Code Thick Film Chip ResistorsResistance Value The first two or three digits are significant figures of resistance and the third or fourth one denotes The SMD resistor packages and their sizes are listed below. More information is available in the discussion of Resistor Sizes and Packages Welcome to the SMD Codebook! For different package styles, the dimensions in mm and in inches are given below. The size of SMD resistors is indicated by a numerical code, such as This code describes the length and width of the package. The SMD Codebook is a reference for Surface Mount Device semiconductor device codes, equivalents and connectionsSMD Codebook Codes beginning with '0' be sure to check the 'O' (letter O) table as well Code Device Manf Base Package Leaded Equivalent/DataSC Nec CX SOT Npn RF fT 7GHz SMD resistors on a printed circuit board.
