74479762133

The 74479762133 is a power multilayer inductor from Würth Elektronik's WE-PMI series. It offers an inductance of 0.33 µH (330 nH) with ±20% tolerance, measured at 1 MHz and 5 mA. The component is rated for a continuous current of 1.1 A (ΔT = 40 K) and 800 mA (ΔT = 20 K), with a saturation current of 1.2 A. Its typical DC resistance is 160 mΩ, with a maximum of 200 mΩ. The self-resonant frequency is at least 200 MHz, and the minimum Q factor is 7 at 1 MHz. This unshielded multilayer inductor is designed for surface mount applications in a 0603 (1608 metric) package, measuring 1.6 mm x 0.8 mm x 0.55 mm. It operates over a temperature range of -40°C to +125°C, with ambient temperature for rated current up to +85°C. The component is RoHS, REACH, and halogen-free compliant, with MSL level 1. Typical applications include power supply circuits, DC-DC converters, and EMI filtering in compact electronic devices.
