1. Overview

KitsInductor Kits are modular assemblies containing inductors with varying specifications, designed for rapid prototyping, educational purposes, and industrial applications. Inductors are passive electronic components that store energy in magnetic fields and resist current changes. They are critical in power management, signal filtering, and electromagnetic interference (EMI) suppression. Modern electronics rely on inductors for efficient voltage regulation in devices ranging from smartphones to industrial machinery.
