Filter inductor WL0625

RFmagneticferrite core

Overview
The WL0625 ferrite core inductor delivers stable inductance across a wide range with low core losses and compact dimensions suitable for PCB-mounted power and filtering circuits. It stores energy during switching events and suppresses conducted noise in high-frequency applications, supporting reliable operation across typical industrial temperature ranges.

Construction and materials

• Core material: ferrite magnetic material for high permeability and low core losses
• Conductor: enameled copper wire with polyester insulation
• Construction types: radial and SMD variants available
• Mounting: PCB through-hole (radial) and surface-mount (SMD)

Shapes and customization

• Available shapes: toroidal, rod-type, drum core and other geometries
• Customizable parameters: inductance value, tolerance, rated current, DC resistance (DCR), mechanical dimensions and current handling
• Manufacturer services: OEM production and tailored designs for specific inductance, size and current requirements

Applications

• Switching power supplies and DC–DC converters (energy storage during switching)
• EMI/RFI filters and noise suppression networks
• Consumer electronics: TVs, laptops, mobile devices
• Industrial equipment: motor drives, automation controllers, power modules
• Automotive electronics: engine control units, lighting drivers, power distribution
• Communication equipment: routers, radio modules, network devices
• Renewable energy and charging systems: solar inverters, battery chargers

Advantages
High magnetic permeability enables compact designs with substantial inductance; low eddy-current losses improve efficiency at high switching frequencies; stable electrical properties and low EMI in properly selected configurations.

Disadvantages
Ferrite cores are mechanically brittle and may be damaged by impact; lower saturation flux density than some metal alloy cores can limit high-current performance without careful design.
