7447789270 Description

Short technical summary and product information.

The Würth Elektronik 7447789270 is a robust SMT shielded power inductor from the WE-PD series. It offers an inductance of 270µH (measured at 1kHz/250mV) with a tolerance of ±20%. The component is rated for a continuous current of 400mA (ΔT=40K) and can handle a performance rated current of 560mA per IEC 62024-2-2020. Saturation current is 390mA typical at 10% inductance drop and 480mA typical at 30% drop.

 

The inductor features a maximum DC resistance of 2.31Ω (1.47Ω typical) and a self-resonant frequency of 5.2MHz. It is designed for an operating voltage up to 120V and an ambient temperature range of -40°C to +85°C (operating temperature -40°C to +125°C). The component is AEC-Q200 Grade 1 qualified, making it suitable for automotive applications.

 

Packaged in a nonstandard 7332 surface-mount case (7.30mm x 3.20mm x 3.50mm), the inductor is shielded to minimize EMI. It is compliant with RoHS, REACH, and Halogen Free standards, and has an MSL rating of 1 (unlimited).
