## How to Read Chip Resistor ?

With the continuous development of new technologies, more and more products need to use resistors, making the types of resistors more and more. The main ones are: chip resistors, thin film and thick film resistors, metal film resistors, carbon film resistors, Winding resistance, etc. Chip resistors in the circuit have the advantages of small size, light weight, stable electrical performance, high reliability, low assembly cost, high mechanical strength, high-frequency characteristics, etc.; due to these characteristics, we can see chip resistors in many circuits The use of, usually has a string of numbers on its surface, which represents some resistance performance of the chip resistor.

So how to read the numbers of chip resistance? The more resistance, the more difficult it is to distinguish its resistance, accuracy, power, material, etc. The following editor will introduce you all:

Resistance conversion relationship Ω=Ωk=kΩ=1,000ΩM=MΩ=1,000,000Ω Thecode on the micro-chip resistor is generally marked with 3 digits or 4 digits...

Resistance conversion relationship

Ω = Ω

k = kΩ = 1,000 Ω

M = MΩ = 1,000,000 Ω

Resistance conversion

The identification of the resistance value of the chip resistor is actually very simple. The resistance value of the chip resistor is printed on the surface. When reading the resistance value of the chip resistor, you can directly look at the number on the surface of the resistor; the chip resistance is composed of three numbers, which means the resistance error is ±5 %. The first two digits are significant digits, and the third digit indicates the multiplying rate by zero. The basic unit is Ω. For example, 102, 1 and 0 are significant digits and just write them down directly, 2 means multiplying by zero, that is, the power of 10 (simply put, the third digit is what is the power of 10)

To

We can easily understand the chip resistance identification method through the following examples:

10×1000=10000Ω=10KΩ

103=10×1000=10000Ω=10KΩ

223=22×1000=22000Ω=22KΩ

122=12×1000=1200Ω=1.2KΩ

301=30×10=300Ω

850=85×(zero power of 10=1)=85Ω

1R0=1.0Ω

2. The chip resistor is composed of four numbers, indicating that the error of the resistance is ±1%. The first three digits are significant digits, and the fourth digit represents the multiplication by zero (that is, the number is how many times it represents the power of 10). For example, 1502, 150 are valid digits, just write them down, 2 means 10 squares.

So the resistance of 1502 is 150×10 squared = 150×100=15000Ω=15KΩ

3. To read the resistance value of the chip resistor composed of numbers and letters, we only need to change R to a decimal point.

10R6=10.6R=10.6Ω R12=0.12R=0.12Ω
