744760247A Description

Short technical summary and product information.

The 744760247A from Würth Elektronik is a WE-RFI series ferrite SMT inductor with a nominal inductance of 0.47 µH (±5%) measured at 25.2 MHz. It features a minimum Q-factor of 45 at 100 MHz and an impedance of 280 Ω (±25%) at 100 MHz, with a typical maximum impedance of 4725 Ω at 700 MHz. The component is rated for a maximum DC resistance of 0.5 Ω at 20 °C and has a self-resonant frequency of at least 375 MHz.

 

This unshielded drum core inductor is designed for surface-mount assembly in an 0805 (2012 metric) package with dimensions of 2.0 mm x 1.2 mm x 0.5 mm. It supports a maximum rated current of 500 mA at a temperature rise of 15 K, and 650 mA at a 40 K rise. The operating temperature range is -40 °C to +85 °C, with storage conditions below 40 °C and 75% relative humidity.

 

The inductor is RoHS3 compliant, REACH conform, halogen-free per JEDEC JS709B and IEC 61249-2-21, and qualified to AEC-Q200 Grade 3 for automotive applications. It is suitable for general electronic equipment and automotive-grade applications where its impedance characteristics and current handling are required.
