Keadic 25 Pcs Toroid Magnetic Core Inductor Copper Wire Wind Wound Assortment Kit, Inductance Coil Perfect for Transformers DIY Circuit Board（ 22UH-5A 47UH-3.8A 220UH-1.96A 330UH-1.96A 100UH-2.8A ）

◆ Product Feature: 1. Widely used in power switch, power cable or signal cable, noise suppression filter, power cable and signal cable ESD filter. The toroid Core inductor has less working frequency impedance, high magnetic permeability, less magnetic-leakage loss. 2.The main function of an inductor is to obstruct changes in current. When the circuit is turned on, if there is no current passing through the inductor, it will attempt to obstruct the flow of current; When the circuit is disconnected, if there is current passing through the inductor, it will attempt to maintain the current constant. 🛠️ Ideal Applications Power supply filtering (SMPS, linear regulators) Audio equipment (preamps, amplifiers, crossovers) Motor control circuits RF filtering & signal conditioning DIY Arduino/Raspberry Pi projects needing stable inductance 📦 What You Get 5 x 22UH-5A Toroidal Inductors 5 x 47UH-3.8A Toroidal Inductors 5 x 220UH-1.96A Toroidal Inductors 5 x 330UH-1.96A Toroidal Inductors 5 x 100UH-2.8A Toroidal Inductors 💡 Why Choose Our Toroidal Inductors?

• 👍【 Precision Engineering】Toroidal design minimizes EMI (electromagnetic interference) for cleaner signal transmission – ideal for audio amplifiers, LED drivers, and switching power supplies.
• 👍【5 Various Kinds Toroid Magnetic Core Inductor】This set has 5 different types of inductors, which are characterized by passing direct current and resisting alternating current. The higher the frequency, the greater the coil impedance. Inductors typically work together with capacitors in circuits to form LC filters, LC oscillators, and so on.
• 👍【 Compact & Universal】All inductors share a 0.55” (14mm) height and 0.02” (0.6mm) lead diameter, fitting standard PCB layouts and breadboards.In addition,high-purity copper windings ensure low resistance, efficient heat dissipation, and long-term reliability.
• 👍【Inductance Coil Function】The inductance coil has multiple functions, which can store electric energy, adjust current changes in the circuit, and ensure current stability. In addition, the inductance coil can protect the circuit from external interference, participate in electric energy conversion, transmit signals, play a key role in transformers, motors and other equipment.
• 👍【Wide Application】These toroidal inductors are widely used in power switch, power cable or signal cable, noise suppression filter, power cable, signal cable ESD filter, power lines, signal lines, miniature TVs, adapters, DC-DC step-up / step-down power modules, various electronic products, etc.
