SMD resistors are commonly referred to as "chip fixed resistors" in terms of model specifications, packaging dimensions, and surface mount resistors

Also known as "Chip Fixed Resistors" or "Rectangular Chip Resistors", chip resistors were first invented by ROHM and introduced to the market. Surface mount resistors have uniform appearance dimensions, precision, and small temperature coefficient and resistance tolerance. They are characterized by moisture resistance, high temperature resistance, and high reliability. http://www.xiangrudz.com

The inch markings for surface mount resistor packaging are: 020104020603080512061210121220102512. The precision of its conventional series is 5% and 1%. The resistance range is from 0.1 ohms to 20M ohms. The standard resistance values are E24 and E96 series. The power includes 1/20W, 1/16W, 1/8W, 1/10W, 1/4W, 1/2W, and 1W.

There are 9 common packaging types for surface mount resistors, represented by two size codes. A type of surface mount resistor is a metric code, also represented by a 4-digit number, with units in millimeters. http://www.xiangrudz.com Another size code for surface mount resistors is the EIA (Electronic Industries Association) code, which is represented by four digits. The first two digits and the last two digits represent the length and width of the resistor, measured in inches. The 0603 package commonly used for surface mount resistors refers to the imperial code.
