Overview
The Wurth Elektronik 7445620 is a high-performance, unshielded ferrite power inductor designed for demanding DC-DC converter applications. Its primary function is to store and release energy, smoothing current ripple and enabling efficient voltage regulation. A critical design consideration for this WE-PD4 series component is the trade-off between its relatively high DC resistance (330 mOhms) and its substantial DC current handling capability (1.4 A). While the resistance contributes to power loss, the robust construction allows for significant current flow, making it suitable for applications where space is constrained but power delivery is paramount, necessitating careful thermal management to prevent exceeding the +125°C maximum operating temperature.
Key Features
- Inductance: 100 µH
- Tolerance: ±10%
