Resistor SMD code calculator for 4 different code types is a lightweight, free alternative for our engineers and enthusiasts. A full version with no Ads.

Resistor SMD code calculator will code and decode 4 code types:

Standard 3 digit code that can include:
- R to indicate a decimal point
- M to indicate a decimal point for milliohms (Current sensing SMDs)
- ""underline"" to indicate that the value is in milliohms (Current sensing SMDs)

Standard 4 digit code that can include “R” to indicate a decimal point.

EIA-96 1% code with a number in the range 01 to 96, followed by a letter

2, 5, and 10% code with a letter, followed by a numbers in the range 01 to 60

Supported letters in this calculator include the following codes: A, B, C, D, E, F, H, M, R, S, X, Y, Z and the underline.
