74457082 Description

Short technical summary and product information.

The Würth Elektronik 74457082 is a fixed inductor from the WE-PD4 series. It features an inductance of 8.2 µH with ±20% tolerance, measured at 100 kHz / 1 V. The rated current is 7 A maximum at a 40 K temperature rise, with a typical saturation current of 11 A (|ΔL/L| < 10%). DC resistance is 0.016 Ω typical and 0.019 Ω maximum. The self-resonant frequency is 23 MHz typical, and the maximum operating voltage is 120 V DC.

 

This inductor uses an unshielded drum core construction with a ferrite core. It is surface mountable in a nonstandard package measuring 22.00 mm x 15.00 mm x 7.80 mm. The operating temperature range is -40°C to 125°C, with a derated ambient temperature of up to 85°C at rated current. Storage conditions recommend less than 40°C and 75% RH.

 

The component is compliant with RoHS (2011/65/EU & 2015/863), REACH ((EC)1907/2006), and Halogen Free (JEDEC JS709B) standards. Moisture Sensitivity Level is MSL 1 (unlimited). The datasheet confirms all electrical and environmental specifications.
