744773047 Description

Short technical summary and product information.

The Würth Elektronik 744773047 is a surface mount power inductor from the WE-PD2 series. It features a drum core, wirewound construction with a ferrite core and is unshielded. The inductor provides 4.7 µH inductance with ±20% tolerance, measured at 10 kHz/100 mV.

 

Electrical characteristics include a rated current of 1.82 A (maximum, ΔT = 40 K), typical saturation current of 2.46 A (|ΔL/L| < 10%), typical DC resistance of 0.059 Ω and maximum DC resistance of 0.11 Ω at 20 °C. The self resonant frequency is 50 MHz typical, and the maximum operating voltage is 120 V DC.

 

The component is rated for operating temperatures from -40 °C to +125 °C, with ambient temperature (referring to IR) from -40 °C to +85 °C. Storage conditions in original packaging are below 40 °C and below 75% relative humidity. The moisture sensitivity level is 1, allowing unlimited floor life.

 

Mechanically, the inductor measures 4.50 mm x 4.00 mm with a height of 3.50 mm, and uses a nonstandard surface mount package (size code 4532). It is RoHS compliant, REACH conform or declared, and halogen free per JEDEC JS709B and IEC 61249-2-21.
