Surface Mount Device Identification

A case tantalum bottom and side 2.

Surface mount device identification.

Under devices select surface headphones then select device details. 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. Open the surface audio app select settings next to surface headphones then select about. Enter package marking and press search.

Select the start button then type system information. The surface mount resistor code systems provide are mainly used to enable service repair and fault finding. During manufacture the resistors are held either in tapes that are reeled or in hoppers used for the surface mount machines. To look up a coded device click on the first character of the device code in the table on the left.

The surface mount device code book r p blackwell gm4pmk. Smd devices are by their very nature too small to carry conventional semiconductor type numbers. D case tantalum capacitor top and side 3. Surface mount technology smt is a method in which the electrical components are mounted directly onto the surface of a printed circuit board pcb.

Instead a somewhat arbitrary coding system has grown up where the device package carries a simple two or three character id code. To identify a particular smd device first identify the package style and note the id code printed on the device. Identification pictures for surface mount devices smd all images and text are copyright vk3em luke enriquez c 2000. Find system model under the item column.

Surface mount technology or smt is the name of the method used for producing an smd. You ll find the serial number there. On an ios device or android device. If you are unsure of a character enter.

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. Electrolytic capacitor side view 4. 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. The model info for your surface will appear in the value column next to system model.

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. This search engine designed to help identify the part from this code. Unfortunately each device code is not necessarily unique.
