What is the marking code for SMD components?
They use instead a marking code typically composed of a combination of 2 or 3 letters or digits. When repairing an unknown electronic board, it becomes so difficult to know what is the exact type of a given component. This database allows to quickly find the part number of a SMD component when you have only the marking code.
Why don’t SMD cases have the full part numbers?
Due to the small size of most SMD components, manufacturers are not able to write the full part number on the case. They use instead a marking code typically composed of a combination of 2 or 3 letters or digits.
How do I identify an SMD device?
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.
What are SMD resistors and how are they coded?
SMD Resistors are usually coded with a numerical equivalent of the familiar three band colour code. In the same way as wire ended components, precision resistors (1% or better) may be marked with a four digit code.
How many SMD-codes are there for active semiconductor components?
• 235.000 SMD-codes for active semiconductor components: • Diodes, Transistors, Thyristors, Integrated Circuit s • Case pin assignment • Pinout • Marking style • Schematic diagram • Additional SMD info • Case drawings • Manufacturers 2012 EDITION Eugeniu Turuta Martin Christian Turuta
How to solve SMD-code compliance with different manufacturers?
Compliance with the name and type of cases from different manufacturers is solved by applying in the column “Case” an equivalent type name for equivalent cases. In addition to SMD-code, uper case may be put padding alpha-numeric information (usually by another font or size of characters, also may be by other arrangement).
How many SMD marking codes are there for bipolar transistors?
Our database currently has 3343 SMD marking codes of bipolar transistors (BJT), field effect transistors (FET, MOSFET, JFET), diodes, Zener diodes, Schottky diodes, varicap diodes, voltage supervisors (reset circuits), temperature sensors, current sensors, transient voltage suppressors (TVS) and others.
