744032221

The Würth Elektronik 744032221 is a WE-LQ series SMT power inductor designed for general electronic equipment. It features a drum core, wirewound construction with a ferrite core and is unshielded. The inductor offers an inductance of 220µH with ±10% tolerance, measured at 1 MHz and 100 mV. It has a maximum rated current of 75 mA (based on a 40 K temperature rise) and a typical saturation current of 240 mA. The maximum DC resistance is 11.8Ω at 20°C. The self-resonant frequency is typically 5 MHz, and the Q factor is 40 at 0.796 MHz. The component can operate at voltages up to 120 V DC. It is designed for surface mount assembly in a 1210 (3225 Metric) package with dimensions 3.20 mm x 2.50 mm x 2.30 mm. The operating temperature range is -40°C to +125°C, with an ambient temperature range of -40°C to +85°C for rated current. The inductor is RoHS compliant, REACH conform, and halogen-free. It is suitable for power supply filtering, DC-DC converters, and other low-power applications where a compact, surface-mount inductor is required.
