7447709004 Description

Short technical summary and product information.

The Würth Elektronik 7447709004 is a shielded surface-mount power inductor from the WE-PD series. It features a drum core with ferrite material and wirewound construction, providing an inductance of 4.7 µH at 1 kHz/250 mV with ±20% tolerance. The component is rated for a maximum DC resistance of 11 mΩ and a typical DC resistance of 7 mΩ at 20 °C.

 

This inductor supports a rated current of 9.3 A (ΔT=40K) and a performance rated current of 13.1 A per IEC 62024-2-2020 Class B. Saturation current is 13 A typical at 10% inductance drop and 16 A typical at 30% drop. The self-resonant frequency is 38 MHz typical, and the maximum operating voltage is 120 V.

 

The component is qualified to AEC-Q200 Grade 1 and is released for automotive applications. It operates over a temperature range of -40 °C to +125 °C, with ambient temperature up to +85 °C referring to IRP. The inductor is RoHS compliant, REACH conform, and halogen free.

 

The package measures 12.0 mm x 12.0 mm with a maximum height of 10.0 mm, and is designed for surface mounting in a nonstandard package. The moisture sensitivity level is 1, and storage conditions are below 40 °C and 75% relative humidity.
