7447709222 Description

Short technical summary and product information.

The Würth Elektronik 7447709222 is a shielded surface mount power inductor from the WE-PD series. It features a ferrite core and is designed for high current handling in a compact 12.0mm x 12.0mm x 10.0mm max package. The inductor offers an inductance of 2200 µH ±20% measured at 1 kHz and 250 mV. Its rated current is 530 mA maximum at a 40K temperature rise, with saturation currents of 0.75 A (10% drop) and 0.92 A (30% drop) typical. DC resistance is 3.25 Ω typical and 3.75 Ω maximum at 20°C. The self-resonant frequency is 0.66 MHz typical, and the maximum operating voltage is 120 V. This component is qualified to AEC-Q200 Grade 1 for automotive applications and operates over a temperature range of -40°C to 125°C. It is RoHS, REACH, and Halogen Free compliant with MSL Level 1. The shielded construction helps reduce electromagnetic interference, making it suitable for power supply filtering, DC-DC converters, and other power management circuits.
