The Würth Elektronik 744777133 is a surface-mount shielded power inductor from the WE-PD series. It features a ferrite drum core with wirewound construction, providing an inductance of 33 µH at 1 kHz and 250 mV with a tolerance of ±20%. The component is rated for a continuous current of 1.13 A based on a 40 K temperature rise, with a performance rated current of 1.9 A per IEC 62024-2-2020 Class C. Saturation current is typically 1.4 A at 10% inductance drop and 1.7 A at 30% drop.
The inductor offers a typical DC resistance of 140 mOhm and a maximum of 170 mOhm, with a self-resonant frequency of 13 MHz. It is designed for a maximum operating voltage of 120 V and operates over a temperature range of -40 °C to +125 °C. The component is shielded to minimize electromagnetic interference and is qualified to AEC-Q200 Grade 1 for automotive reliability.
Packaged in a 7345 (Nonstandard) SMD format measuring 7.3 mm x 7.3 mm with a maximum height of 4.5 mm, this inductor is suitable for power supply and DC-DC converter circuits in space-constrained designs. It is RoHS, REACH, and halogen-free compliant, with an MSL of 1 for unlimited floor life.
