Bobbins (coil formers), mounts, and hardware are critical mechanical components in magnetic devices. Bobbins serve as structural supports for wound coils in transformers and inductors, while mounts/hardware ensure mechanical stability and electrical connectivity. These components enable precise winding alignment, thermal management, and electromagnetic interference (EMI) control, playing a vital role in power electronics, automotive systems, and industrial equipment.
| Type | Functional Features | Application Examples |
|---|---|---|
| Transformer Bobbins | Provide winding support with insulation barriers | Switch-mode power supplies (SMPS), AC/DC converters |
| Inductor Coil Formers | Enable precise winding geometry for inductance control | DC/DC converters, EMI filters |
| PCB Mounts | Secure components to printed circuit boards | Telecom equipment, automotive ECUs |
| Core Clamps | Mechanical fixation for ferrite/powder cores | High-frequency transformers, PFC circuits |
Typical bobbin structures include:
Mounts/hardware feature:
| Parameter | Importance |
|---|---|
| Temperature Resistance (130-200 C) | Determines thermal stability and lifespan |
| Dielectric Strength (>2kV) | Ensures safety isolation between windings |
| Dimensional Tolerance ( 0.05mm) | Impacts winding machine compatibility |
| Tensile Strength (>50MPa) | Prevents mechanical deformation under load |
| Surface Resistivity (10^12 ) | Prevents leakage current paths |
| Manufacturer | Representative Products |
|---|---|
| TDK-Lambda | Compact PCB-mount bobbin series for telecom |
| Sumec Corporation | High-temp composite coil formers |
| Eaton Electronics | Vibration-resistant inductor mounts |
| Fastron IC | Customizable toroidal core hardware kits |
Key considerations:
Case Study: Electric vehicle chargers use high-temperature bobbins (UL 1557 recognized) to withstand 150 C continuous operation.
Emerging developments include:
Market drivers: Electrification of transportation, 5G infrastructure deployment, and energy-efficient appliance standards.
