7443330330 Description

Short technical summary and product information.

The Würth Elektronik 7443330330 is a WE-HCC series SMT high current cube inductor. It offers an inductance of 3.3µH with ±20% tolerance, measured at 100kHz/10mA. The component is rated for a continuous current of 14.1A (ΔT=40K) and features a typical DC resistance of 6.5mΩ (max 7.15mΩ). Saturation currents are 19.3A (10% drop) and 22.8A (30% drop) typical. The self-resonant frequency is 51MHz typical, and maximum operating voltage is 120V.

 

This shielded inductor uses a ferrite core with wirewound drum core construction, minimizing EMI. It is qualified to AEC-Q200 Grade 1, making it suitable for automotive applications. Operating temperature range is -40°C to +125°C. The component is RoHS, REACH, and halogen-free compliant with MSL Level 1.

 

The package is a nonstandard SMD form factor measuring 10.90mm x 10.00mm x 9.70mm. It is designed for surface mount assembly and is compatible with high-current power supply and DC-DC converter designs.
