7447070 Description

Short technical summary and product information.

The 7447070 is a WE-FI leaded toroidal line choke manufactured by Würth Elektronik. It features an inductance of 100 µH with ±20% tolerance measured at 10 kHz and 5 mA. The rated current is 6 A maximum based on a temperature rise of 40 K, and the DC resistance is 35 mΩ maximum at 20°C. The component is designed for through-hole mounting in a radial, vertical open package with a ferrite core. It is unshielded.

 

Operating temperature ranges from -40°C to 105°C, with the rated current specified for ambient temperatures up to 65°C. Storage conditions recommend below 40°C and 75% relative humidity. The choke is certified RoHS compliant (2011/65/EU & 2015/863), REACH conform (EC 1907/2006), halogen free (JEDEC JS709B, IEC 61249-2-21), and has MSL Level 1.

 

Typical applications include line filtering in power supplies, EMI suppression in DC-DC converters, and general purpose inductor use in electronic equipment. The component is not authorized for use in safety-critical applications such as military, aerospace, medical, or automotive systems without specific agreement with Würth Elektronik.
