Wurth Elektronik WE-MAPI SMT Series Power Inductor, 4.7μH Inductance, 6.4A Maximum DC Current - 74438357047

This power inductor is a shielded surface-mount component designed to manage energy storage and filtering in high-current electronic circuits. It uses a manganese‑zinc core to provide inductance while operating across a wide temperature range from -40°C to 125°C, and is supplied in tape and reel for automated placement. The component meets multiple industry standards for use in demanding environments.

Features and Benefits:

• 4.7 μH inductance reduces ripple in power rails
• 6.4A current rating supports high-current designs
• 24MHz SRF allows operation up to the self‑resonant frequency
• 44mΩ low DCR minimises conduction losses
• Shielded construction reduces EMI for Compact layouts

Applications

• Suitable for buck converter input and output filtering
• Ideal for automotive power management modules
• Used with high-current DC‑DC converters on boards
• Can be used for EMI suppression in Compact assemblies

What encapsulation or packaging is used for automated assembly?

It is delivered in tape and reel suitable for pick‑and‑place systems.

Which material forms the magnetic core and what does it provide?

The core is manganese‑zinc and it provides the necessary permeability for stable inductance.

What is the permissible operating temperature range for reliable use?

The allowable temperature window spans from -40°C up to 125°C.

How does the inductor address electromagnetic interference concerns?

The component features a shielded construction that contains flux and reduces radiated emissions.
