Splet22. dec. 2024 · 1) Chip Resistors (R) Chip Resistors are the most common SMD parts that manufacturers use on SMT PCBs. Usually, the 3 numbers on the body of a chip resistor show its resistance value. the 1 st and 2 nd digits are significant digits, and the 3 rd digit indicates the multiple of 10, such as “105” indicates “1MΩ”, “672” is “6.7KΩ”. Transformers generally consist of two physically separated coils that are inductively coupled through the magnetic field, which is incident between the primary and secondary coils.
