Basic knowledge and model purchase of SMD adjustable resistors

There are many specifications and models of adjustable resistors. In general, the resistance error of SMD adjustable resistors is divided into various precisions such as ± 20%, ± 10%, ± 5%, ± 1%, etc. The most used is ± 5% and ±1% accuracy, ±5% accuracy. The 103 printed on the patch adjustable resistor, the first 2 digits 10 represent effective digits, the third digit 3 represents the magnification, which is 10 to the 3rd power, so the resistance value of 103 should be 1000 ohms, which is 10k, the accuracy Is 5%. 1502 printed on the patch adjustable resistor: the first three digits 150 represent effective digits, the fourth digit 2 represents the magnification, which is 10 to the 2nd power, so the resistance value of the 1502 patch adjustable resistor should be 15000 ohms, That is 15k, and its accuracy is 1%. There is a type with the letter R. This kind of resistance means that its resistance value has a decimal. The position of the letter R is the position of the decimal point, such as R047, which means 0.047 ohm.

　　 In order to avoid some heat damage during the installation and welding of the SMD adjustable resistor, more attention should be paid to the time of its welding resistance. Usually, the welding time is best kept within 3S to complete the operation. Otherwise, if the soldering is not stable after the time has passed, you need to wait for the resistance of the terminals to dissipate before you can perform the re-soldering of the second operation. Due to the small size of the SMD resistors, the storage of the resistors generally cannot directly leave the resistors in the air for a long time, otherwise it will easily cause oxidation of the resistors, so that the post-positioning reduces its solderability. On the other hand, SMD adjustable resistors should also pay attention to the storage environment, and should not be placed in places with excessive humidity to avoid causing the resistor to become damp and fail.
