Precision chip resistorWhat is it? Precision patch resistance refers to a type of resistor with a relatively small error, commonly referred to as a 1% error patch resistance. The minimum error (accuracy) can reach 0.01%, and the temperature coefficient can be as low as ± 5ppm/℃, which is rarely achieved in the industry. It can be applied to precision instruments, communication electronic products, and portable electronic products.

So many people will ask, can the chip resistance be distinguished by 5% and 1% if it is not tested?

Good question, then let's compare the difference between 5% and 1% chip resistors.

5% Serieschip resistorThree digit representation: the first two digits of this representation method represent the Significant figures of the resistance value, and the third digit represents the number of "0" to be added after the Significant figures. When the resistance is less than 10 Ω, R is used in the code to represent the position of the Decimal separator of the resistance value. This representation method is commonly used in resistance series with a resistance value error of 5%. For example, 330 represents 33 Ω instead of 330 Ω; 221 represents 220 Ω; 683 represents 68000 Ω, which is 68k Ω; 105 represents 1M Ω; 6R2 represents 6.2 Ω

The 1% series precision chip resistance is represented by four digits: the first three digits of this representation represent the Significant figures of the resistance value, and the fourth digit represents the number of 0 to be added after the Significant figures. When the resistance is less than 10 Ω, R is still used in the code to indicate the position of the Decimal separator of the resistance value, which is generally used in the precision resistance series with a resistance error of 1%. For example, 0100 represents 10 Ω instead of 100 Ω; 1000 represents 100 Ω instead of 1000 Ω; 4992 represents 49900 Ω, which is 49.9k Ω; 1473 represents 147000 Ω, which is 147k Ω; 0R56 represents 0.56 Ω.

The surface of the SMD resistor is engraved with letters. If there are only three digits, it is an error of 5%, and if there are four digits, it is an error of 1%.
