How do you read a 4 digit SMD resistor?
How do you read a 4 digit SMD resistor?
The first two numbers will indicate the significant digits, and the third will be the multiplier. ‘R’ is used to indicate the position of a decimal point. Similar to the three digit EIA, the four digit format uses the beginning values to indicate the significant digits while the last digit is the multiplier.
What is the value of the resistor marked 2R2?
2.2Ohm
3-Digit Series Resistors
| Code | Value |
|---|---|
| 2R0 | 2Ohm |
| 2R2 | 2.2Ohm |
| 2R4 | 2.4Ohm |
| 2R7 | 2.7Ohm |
What does 4R7 resistor mean?
4.7 ohms
Lower values use “R” as a decimal point. For example 4R7 = 4.7 ohms, 34R8 = 34.8 ohms.
How do you read a SMD resistor?
Reading a SMD resistor code
- the first two numbers indicates the significant digits for the resistance, e.g. “22” indicates 22 ohms.
- the third number will be a multiplier that must be multiplier by the first two numbers, or will indicate how many zeros should be added to the first two numbers.
What does 4R7 mean?
4R7 means 4.7 Ohms. 47K means 47 Kilo Ohms = 47 kΩ = 47000 Ohms. 4K7 means 4.7 Kilo Ohms = 4.7 kΩ = 4700 Ohms.
What does the W stand for in resistors?
Yes, the “W” is for Watts. The Wattage rating represents the total power (in Watts) that the resistor can safely handle without overheating and destroying itself. You can determine the needed “W” rating by calculating the total current flow through the circuit, at a given voltage.
What does J mean on a resistor?
Tolerance is indicated as. F = +- 1% G = +- 2% J = +- 5%
How do you decode the resistance of a SMD resistor?
Standard-tolerance SMD resistors use a 3-digit code to mark the resistance value on the part. The first two numbers will indicate the significant digits, and the third will be the multiplier. ‘R’ is used to indicate the position of a decimal point.
What is G in resistor?
1M. Tolerance is indicated as. F = +- 1% G = +- 2% J = +- 5%
What is the Colour code for 3K resistance?
3K Ohm Resistor Color Code: Orange, Black, Red, Golden. Resistance: 3K Ohm, Power Rating: 0.25 Watt, Approximate Maximum Current: 9.13mA .
What does 3m3 mean on a resistor?
The last digit indicates the number of zeroes in the resistor value, while the preceding two or three numbers define the value itself. Letter R is used to indicate a decimal point. Thus a 3R3 surface-mount resistor has a value of 3.3 Ohms, while 330 would indicate 33 Ohms, and 332 indicates 3,300 Ohms.
What does 8K2 resistor mean?
For example, 8K2 indicates a resistor value of 8.2 kΩ. Additional zeros imply tighter tolerance, for example 15M0 . When the value can be expressed without the need for a prefix, an “R” is used instead of the decimal separator. For example, 1R2 indicates 1.2 Ω, and 18R indicates 18 Ω.
