D.E.V.I.C.E. is an encyclopedia of terms used by manufacturers of test and measurement equipment. T&M Atlantic created this service to better explain the functionality of instruments it offers, and to highlight the latest developments in the world of measurement equipment. We are using such tools as animation to bring words and pictures to life and to create not just an understanding but also an appreciation for technology that goes into the design of every instrument.

SMD Inductor Code Calculator allows you to determine inductance of a SMD (surface mount device) inductor by the markings found on the device and to determine SMD inductor markings by inductance. It displays rated inductance and inductor tolerance.
This tool supports 2- and 3-digit codes. "R" is used to indicate the position of a decimal point for µH values. "N" is used to indicate the position of a decimal point for nH values. "D" is used to indicate ±0.3nH tolerance, "J" - ±5% tolerance, "K" - ±10% tolerance, "M" - ±20% tolerance.
