The SMD resistor calculator is an online tool for finding the resistance of surface-mount device (SMD) resistors from their markings.
How to Use Our SMD Resistor Calculator?
The operation of our SMD resistor value calculator remains straightforward. Just follow these steps:
- Look at your SMD resistor: to determine whether it uses a 3-digit, 4-digit, or EIA-96 (2 numbers + 1 letter) marking system.
- Enter the Marking: Input the code using the keypad. The resistance value is calculated automatically as you type.
- Clear the Input: Use the "DEL" key to backspace or the "Clear" button to start over.
- surface mount resistor calculator: SMD (Surface Mount Device) resistor is also called a surface mount resistor because it is mounted on the surface of a printed circuit board (PCB) and The reference resistor has a code on it and its value is based on each code. it is a type of electronic component designed to be mounted directly onto the surface of a PCB.
SMD Resistor Calculator Example
- 101 SMD resistor value 101 SMD resistor code a 3-digit code commonly used for standard SMD resistors (±5% tolerance).
The first two digits = significant figures → 10
The third digit = multiplier number of zeros to add→ 1 zero
10 × 0 = 100 Ω
Answer 100 Ω
- “01C” SMD Resistor Code: The “01C” SMD resistor code follows the EIA-96 SMD resistor chart for 1% tolerance SMD resistors.
First two characters (“01”) → refer to a value from the EIA-96 table chart.
01 = 100 (base value)
Letter (“C”) → is the multiplier code.
From the EIA-96 multiplier chart:
C = ×100
final answer = 10K
- 102 smd resistor value :
The SMD resistor code 102
The first two digits = 10
The third digit = number of zeros to add = 2 zeros
10 × 100 =
1000 Ω
Value = 1 kΩ {kilo-Ohms}
- 432 smd resistor value 3-Digit SMD Code:
Code: 432
First two digits = 43
Third digit = multiplier = 10² = 100
43×100=4300Ω=4.3kΩ43 × 100 = 4300 Ω = 4.3 kΩ43×100=4300Ω = 4.3kΩ
432 smd resistor value= 432 → 4.3 kΩ (±5%)
- 100 smd resistor value SMD Code:3-Digit:
Code: 100
First two digits = 10
Third digit = multiplier = 1
10 × 10^0 = 10 × 1 = 10 Ω
100 smd resistor value= 10 → 10Ω (±5%)
- 1000 smd resistor value
When you look at an SMD resistor and it's just marked "1000" and that's it, here's the lowdown - I'll break it down for you in a way a real-tech would explain:
- Example: "1000" on that SMD resistor
- 1st: Take that first bit and grab the first three digits - so that's 100.
- 2nd: And that last digit? It's like - how many zeros to tack on? In this case, its 0
- 3nd: So your resistor stays a nice simple 100 ohms.
Just think of it like the code "1000" is just saying "100 - no extra zeros, thanks."
So if you plop it in a circuit and check it with a multimeter - you'll get a reading of roughly 100 ohms.
- Final Answer: 100 Ω (ohms) resistor
Quick Tip:
If you saw a resistor with the code 1001 - that would mean "100 with 1 zero after it" which is 1000 Ω = 1 kΩ.
