Surface Mount Device Identification

Instead a somewhat arbitrary coding system has grown up where the device package carries a simple two or three character id code.

Surface mount device identification.

Smd devices are by their very nature too small to carry conventional semiconductor type numbers. You ll find the serial number there. Modern surface mount electronic components are often too small to write the part number on so a 2 3 or 4 digit code is often used. Identification pictures for surface mount devices smd all images and text are copyright vk3em luke enriquez c 2000.

To look up a coded device click on the first character of the device code in the table on the left. The surface mount resistor code systems provide are mainly used to enable service repair and fault finding. Find system model under the item column. Electrolytic capacitor side view 4.

The surface mount device code book r p blackwell gm4pmk. Enter package marking and press search. A case tantalum bottom and side 2. D case tantalum capacitor top and side 3.

Under devices select surface headphones then select device details. Unfortunately each device code is not necessarily unique. Electrolytic capacitor bottom view 5. On an ios device or android device.

The model info for your surface will appear in the value column next to system model. This search engine designed to help identify the part from this code. During manufacture the resistors are held either in tapes that are reeled or in hoppers used for the surface mount machines. An electrical component mounted in this manner is referred to as a surface mount device smd in industry this approach has largely replaced the through hole technology construction method of fitting components in large part because smt allows.

The serial number is listed there. Surface mount technology or smt is the name of the method used for producing an smd. If you are unsure of a character enter. Surface mount technology smt is a method in which the electrical components are mounted directly onto the surface of a printed circuit board pcb.

A surface mount device or smd is an electronic device for which the components are mounted or placed directly onto the surface of the pcb. To identify a particular smd device first identify the package style and note the id code printed on the device. Now look up the code in the alphanumeric listing which forms the main part of this book by clicking on the first character shown in the left menu.
