744032002

The Würth Elektronik 744032002 is a fixed surface-mount power inductor from the WE-LQ series, featuring a ferrite drum core with wirewound construction. It provides a nominal inductance of 2.2 µH with ±20% tolerance, measured at 1 MHz and 100 mV. The component is rated for a maximum DC current of 620 mA (based on a 40 K temperature rise) and offers a typical saturation current of 1.8 A, ensuring stable performance under moderate load conditions.

Electrical characteristics include a maximum DC resistance of 150 mΩ at 20°C, a typical self-resonant frequency of 50 MHz, and a Q factor of 20 at 1 MHz. The inductor supports a maximum operating voltage of 120 V DC. These parameters make it suitable for power supply filtering, DC-DC converter output stages, and general signal conditioning in compact electronic assemblies.

The device is housed in a 1210 (3225 metric) surface-mount package with dimensions of 3.20 mm × 2.50 mm × 2.30 mm. It is unshielded, which should be considered for EMI-sensitive layouts. The operating temperature range spans -40°C to +125°C, with an ambient temperature range of -40°C to +85°C referenced to the rated current.

This inductor is RoHS3 compliant, REACH conform or declared, and halogen-free per JEDEC JS709B and IEC 61249-2-21 standards. It has a moisture sensitivity level of 1, allowing unlimited floor life before reflow soldering.
