Dongguan Songshen Plastic Electronics Co., Ltd. was established in 2001. For many years, it has been dedicated to chip resistors, chip capacitors, wirewound resistors, plug-in electrolytic capacitors, plug-in carbon film resistors, plug-in gold film resistors, power inductors, chip inductors, Production and sales of chip tantalum capacitor electronic components and representation of synthetic carbon film resistors:
This is an electric power tool used to sand the surfaces of different materials. Belt sanders are equipped with a continuous rotary sanding belt and they can have various rotational speeds. They are known for their parallel chatter marks. They are designed for large surface work on paintwork, filers, and plastics, wood, metal and also stone.
1. Straight standard method
2, text symbol method
3. Digital law:
4. Color-code method: Mark the nominal resistance and allowable deviation on the surface of the resistor with different colored bands or points. Most of the foreign resistors use the color standard method.
Black-0, Brown-1, Red-2, Orange-3, Yellow-4, Green-5, Blue-6, Purple-7, Gray-8, White-9, Gold-±5%, Silver-±10 %, colorless - ± 20%
When the resistance is four-ring, the last ring must be gold or silver, the first two digits are significant digits, the third digit is the power square, and the fourth digit is the deviation.
When the resistance is five rings, the distance between the last ring and the front four rings is larger. The first three digits are significant digits, the fourth digit is the power square, and the fifth digit is the deviation.
Carbon film resistors are generally color coded.
