Identification methods
SMT components have a small size, light weight, high mounting density, high shock resistance. Anti-jamming ability, high frequency characteristics and other advantages, widely used in computers, cell phones, electronic dictionaries, medical electronics, camcorders, electronic meters and VCD machines. According to its shape can be divided into rectangular, cylindrical and shaped three categories. According to the types of resistors, capacitors, inductors, transistors and small integrated circuits. Chip components and general components of the nominal method is different.
The following mainly talk about the chip resistor resistance value nominal method:
The chip resistor resistance value and general resistors, the same in the resistor body labeling. ***There are three types of resistors, but they are not exactly the same as the general resistors.
Digital Soliton Nominal Method
(General rectangular chip resistor using this nominal method)
Digital Soliton Nominal Method is a three-digit number on the resistor body to indicate its resistance value. The first and second digits are valid numbers, and the third digit is the number of "0" added to the valid number. This one will not appear in the letter.
For example: "472′' means "4700 Ω"; "151" means "150 Ω ". If it is a decimal. Then use "R" for "decimal point". And occupy a valid number, the remaining two are valid numbers.
For example: "2R4″ means "2.4Ω"; "R15" means "0.15Ω".
Color Ring Nominal Method
(Generally, cylindrical fixed resistors use this nominal method)
Chip resistors, like general resistors, mostly use four rings (sometimes three) to indicate their resistance value. The first and second rings are valid numbers, and the third ring is the multiplier (color ring code as in Table 1). For example: "brown, green and black" that "15Ω"; "blue, gray, orange and silver" that "68kΩ" error ± 10%.
