Inductor Coil Calculator

Inductor Coil Calculator is a utility tool designed for engineers, technicians, and electronics hobbyists working with inductors and coils.

Key features:

• Inductor Color Codes: Calculate values for 4-band and 5-band color-coded inductors.

• SMD Code Decoder: Decode SMD inductor codes including EIA-96 and numeric formats.

• Coil Inductance: Calculate air-core inductance for single-layer, multi-layer, and flat spiral coil configurations.

• Steel Coil Calculator: Calculate steel coil weight and unwind parameters (lineal feet, layers, feet per layer).

• History Log: Save and view your previous calculations for reference.

• Inductance Unit Converter: Convert values instantly between nH, µH, mH, and H.

• E-Series Finder: Find the closest standard value in E12, E24, and E96 series with percentage deviation.
