What is the formula for SMD Inductor Code (101 = 100µH)?

Core formula: Code ABc = AB × 10^c µH (101 → 10×10¹ = 100µH). The tool returns results instantly using this formula and the selected parameters.

Key points

SMD Inductor Code (101 = 100µH): Two-way conversion between three-digit inductor codes and inductance in µH, including the R decimal notation. Formula: Code ABc = AB × 10^c µH (101 → 10×10¹ = 100µH). Enter parameters on the DD-CAT IDE online tool page to get results instantly, with a calculation-model diagram that updates with the inputs. Inductor codes are in µH (not pF); power inductors often use four digits or an EIA part number — check the datasheet.
