What is a chip precision resistor? What is the difference between chip precision resistors and chip resistors? The chip precision resistor is a chip resistor with an error of 1% or more, and the minimum error (accuracy) of the flat chip resistor can reach 0.01% temperature coefficient as low as ±5ppm/°C in the field of precision resistors. It can be considered relatively rare. What is a chip precision resistor? What is the difference between chip precision resistors and chip resistors?

Many people are puzzled by this. Can the chip resistors distinguish between 1% and 5% chip precision resistors without testing? Below we will analyze in detail where the difference between 1% and 5% is?
The 5% series chip resistors are represented by 3 digits: the first two digits of this representation represent the effective digits of the resistor value, and the third digit indicates the number of "0"s to be added after the significant digit. When the resistance is less than 10Ω In the code, R is used to indicate the position of the decimal point of the resistance value. This representation usually uses a resistance error of 5% in the resistor series. For example: 330 means 33Ω instead of 330Ω; 221 means 220Ω; 683 means 68000Ω or 68kΩ; 105 means 1 MΩ; 6R2 means 6.2 Ω.
The 1% series precision chip resistors are represented by 4 digits: the first 3 digits of this representation represent the effective digits of the resistor value, and the 4th digit indicates the number of 0s that should be added after the significant digit. When the resistance is less than 10Ω, the code still uses R to indicate the position of the decimal point of the resistance value. This method is commonly used in the series of precision resistors with a resistance error of 1%. For example: 0100 means 10Ω instead of 100Ω; 1000 means 100Ω instead of 1000Ω; 4992 represents 49900Ω, ie 49.9kΩ; 1473 represents 147000Ω or 147kΩ; 0R56 represents 0.56Ω.
In fact, it is found that the surface of the chip resistor is engraved with letters. If there are only three digits, then the error is 5%. If there are 4 digits, then the error is 1%. The chip precision resistor is so easy to distinguish. Http://news.chinawj.com.cn
