7447709330 Description

Short technical summary and product information.

The Würth Elektronik 7447709330 is a shielded surface mount power inductor from the WE-PD series. It features a ferrite core and wirewound construction, providing an inductance of 33 µH with ±20% tolerance. The component is rated for a continuous current of 4.2 A (ΔT=40K) and a performance rated current of 5.5 A, with a maximum DC resistance of 45 mOhm at 20°C. Typical saturation currents are 5.5 A at 10% inductance drop and 6.8 A at 30% drop. The self-resonant frequency is 8.5 MHz, and the maximum operating voltage is 120 V.

 

Designed for automotive and industrial applications, this inductor is AEC-Q200 Grade 1 qualified and operates over a temperature range of -40°C to +125°C. It is packaged in a nonstandard 1210 case (12.00 mm x 12.00 mm x 10.00 mm) and is suitable for surface mount assembly. The component is RoHS3 compliant, REACH conform, halogen free, and has an MSL of 1 (unlimited).

 

Typical applications include DC-DC converter output filtering, power supply circuits, and EMI suppression in automotive electronics. The shielded construction minimizes electromagnetic interference, making it ideal for noise-sensitive designs.
