744771220 Description

Short technical summary and product information.

The Würth Elektronik 744771220 is a shielded power inductor from the WE-PD series, designed for surface mount applications. It features a drum core, wirewound construction with ferrite core material, providing high inductance and current handling in a compact 1260 package (12.0mm x 12.0mm x 6.0mm max).

 

Electrically, the inductor offers 220µH ±20% inductance measured at 100kHz/250mV. The rated current (IR,40K) is 1.1A max with a performance rated current (IRP,40K) of 1.85A max per IEC 62024-2-2020. Saturation current is 1.2A typ. at 10% inductance drop and 1.55A typ. at 30% drop. DC resistance is 280mΩ typ. and 340mΩ max at 20°C. Self-resonant frequency is 3.8MHz typ., and maximum operating voltage is 120V DC.

 

Mechanically, the component is shielded to reduce EMI, surface mountable, and has a nonstandard package designated as 1260. It operates over -40°C to +125°C and is qualified to AEC-Q200 Grade 1 for automotive applications. The inductor is RoHS compliant, REACH conform, and halogen free.

 

Typical applications include power supply circuits, DC-DC converters, and EMI filtering in automotive, industrial, and consumer electronics where high reliability and low loss are required.
