Chip Resistor purchase
Five optional parameter chip resistors
Surface mount technology (SMT) has been widespread, the proportion using SMT assembly of electronic products has exceeded 90%. From the beginning of the 1980s should the SMT technology. With the development of small SMT production equipment, SMT further expand the range of applications in aviation, aerospace, instrumentation, machine tools and other fields also using SMT production of various small quantities of electronic products or components.
In recent years, in addition to electronic product development to develop new products using SMD devices, the maintenance staff began assembling a large number of maintenance SMT technology electronic products.
This article describes the application of the largest chip resistors, capacitors and inductors main parameters and specifications, in order to developers, maintenance personnel to purchase these SMD components help.
SMD resistor current models are not uniform, set by the manufacturers themselves, and model particularly long (by the dozen letters and numbers). At the time of purchase if they can make chip resistors various parameters and specifications correctly, it will be able to easily buy (or order) to the desired resistance of.
There are five kinds of chip resistors parameters, namely size, resistance, tolerance, temperature coefficient and packaging.
1. Dimension series chip resistors series generally have seven kinds of size, with two sizes of code to represent. One size codes are EIA (Electronic Industries Association) code consists of four digits, the first two and the last two represent the length and width of the resistance, in inches. Another is the metric code also by the four digits, which in millimeters. The resistance of different sizes, which are different power ratings. Table 1 lists the seven resistance code size and power rating.
2. Resistance series nominal resistance is determined by the series. The series is divided by the resistor tolerances (the tolerances smaller the resistance, the more divided), the most commonly used is the E-24 (tolerance resistance value is ± 5%), as shown in Table 2 .
With three digits to represent the resistance of the chip resistor surface, wherein the first, second place is effective, zero the number of the third digit after the connection. When there is a decimal point with the "R" to represent, and accounting for a significant digits. Nominal resistance code representation as shown in Table 3.
3. Tolerance SMD resistor (carbon film resistors) tolerance has four, namely F grade, ± l%; G grade, ± 2%; J grade, ± 5%; K grade, ± 10%.
4. Temperature coefficient Temperature Coefficient chip resistors are two, namely w level, ± 200ppm / ℃; X grade, ± lOOppm / ℃. Only tolerance for the F-class resistance only use x level, other stages tolerance level of resistance is usually w.
5. Packaging There are two kinds of bulk and strip package.
SMD resistor operating temperature range of -55 - + 125 ℃, the maximum working voltage and size-related: Minimum 0201, 0402 and 0603 to 50V, 0805 for the 150V, other sizes of 200V.
The most widely used chip resistors Size Code
Currently the most widely used chip resistors size of the code is 0805 and 1206. And the gradual development trend towards 0603, 0402 and 0201 in two packages commonly used in products with a higher degree of integration, which also raised the level of technology for SMT high demand. The most common tolerance to J class.
