74438357082 Description

Short technical summary and product information.

The Würth Elektronik 74438357082 is a surface-mount, shielded, molded power inductor from the WE-MAPI series. It offers an inductance of 8.2 µH with ±20% tolerance, measured at 100 kHz and 10 mA. The component is rated for a continuous current of 3.45 A (ΔT=40K per IEC 62024-2-2020, Class C) and features a typical saturation current of 3.35 A at 10% inductance drop and 6.8 A at 30% drop.

 

The inductor has a maximum DC resistance of 86 mΩ (typical 81 mΩ) and a self-resonant frequency of 17 MHz. It is designed for operating voltages up to 80 V DC and can withstand ambient temperatures from -40°C to +85°C for rated current, with an extended operating temperature range of -40°C to +125°C.

 

Packaged in a 1616 (4040 Metric) case measuring 4.10 mm x 4.10 mm with a maximum height of 3.10 mm, this component is suitable for space-constrained power supply designs. It is AEC-Q200 Grade 1 qualified, making it appropriate for automotive electronics, and is RoHS, REACH, and halogen-free compliant.
