Ferrite inductor WL0625

ferrite corewire-woundhigh-frequency

Overview
The WL0625 ferrite core inductor delivers stable inductance with low core losses in a compact package suitable for modern electronic designs. It supports continuous operation across a wide temperature range and is optimized for high-frequency switching and EMI suppression. Typical uses include switching power supplies, DC–DC converters and noise filters.

Construction and materials
Wound with insulated enameled copper wire on a ferrite magnetic core to increase inductance and minimize eddy current losses. The ferrite material’s low electrical conductivity reduces heat generation at high frequencies and improves electromagnetic interference (EMI) performance.

Shapes and customization

• Available shapes: toroidal, rod-type, drum core and other custom shapes
• Customizable parameters: inductance value, rated current, mechanical dimensions, tolerance, mounting style (radial / SMD)

Applications

• Switching power supplies and DC–DC converters (energy storage during switching)
• EMI filters and noise suppression circuits
• Consumer electronics (TVs, laptops, mobile devices)
• Industrial equipment and motor control systems
• Automotive electronics (engine control, lighting modules)
• Communication equipment (routers, RF modules, network devices)
• Solar inverters and battery chargers requiring efficient power conversion
