Wurth Elektronik WE-SL2 Series Wirewound Surface Mount Inductor, 4.7mH Inductance, 500mA Maximum DC Current - 744220
This wirewound surface-mount inductor provides high inductance for power-management circuits and filter networks. Designed for surface-mount assembly with a moulded, shielded dual-core ferrite construction, it operates across a wide temperature range for demanding environments. The component's SMD format and tape-and-reel packaging support automated placement and volume production.
Features and Benefits:
• 4.7mH inductance delivers substantial energy storage for filtering
• 500mA current rating supports moderate power-rail applications
• Low SRF at 100kHz reduces unwanted resonance in low-frequency designs
• ±50% tolerance accommodates coarse-tolerance power designs
• Ferrite dual-core construction provides magnetic confinement and stability
• 500mA current rating supports moderate power-rail applications
• Low SRF at 100kHz reduces unwanted resonance in low-frequency designs
