Ferrite cores are ceramic compounds made from iron oxide and other metal oxides, sintered to form high-permeability magnetic materials. They exhibit low eddy current losses at high frequencies, making them ideal for electromagnetic interference (EMI) suppression, energy storage, and signal transmission in modern electronics. Their unique combination of high resistivity and magnetic properties enables efficient operation in power conversion systems, telecommunications, and automotive electronics.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| EE/EI Cores | High inductance, easy assembly | Switch-mode power supplies (SMPS) |
| RM Cores | Compact design, low leakage inductance | DC-DC converters |
| PQ Cores | High power handling, uniform magnetic path | Automotive battery chargers |
| EP Cores | 360 winding space, mechanical stability | LED drivers |
| Toroidal Cores | Low electromagnetic radiation, high efficiency | RF filters, current sensors |
Typical ferrite cores consist of:
| Parameter | Description | Importance |
|---|---|---|
| Initial Permeability ( i) | Relative magnetic permeability at 10kHz | Determines inductance capability |
| Saturation Flux Density (Bs) | Maximum magnetic flux before saturation | Limits power handling capacity |
| Resistivity ( ) | Volume resistivity ( cm) | Controls eddy current losses |
| Curie Temperature (Tc) | Temperature threshold for magnetic loss | Defines operational temperature limits |
| Dimensional Tolerance | Geometric precision ( 0.05-0.2mm) | Affects winding compatibility |
| Manufacturer | Representative Product | Key Features |
|---|---|---|
