Frequently Asked Questions
What inductance and DC resistance does the Würth 744373240033 provide for DC-DC converter designs?
The 744373240033 offers a nominal inductance of 0.33 µH with an exceptionally low DC resistance of 0.0086 Ω. This combination minimizes conduction losses in high-current switching regulators operating at MHz frequencies, making it well-suited for point-of-load buck converters supplying processors and FPGAs.
Which switching converter topologies can use the 744373240033 in a 1816 SMD case?
Buck, boost, and buck-boost converters targeting output currents above 10 A can use the 744373240033 due to its low 0.0086 Ω DCR and powdered-iron core saturation characteristics. The compact 1816 SMD footprint fits tight PCB layouts in server power modules, telecom rectifiers, and automotive power rails where height is constrained below 2 mm.
How does the powdered-iron core of the 744373240033 compare to ferrite in high-frequency switching applications?
Powdered-iron cores exhibit a softer saturation curve than ferrite, so the 744373240033 maintains its 0.33 µH inductance more gracefully under peak currents exceeding the rated limit, preventing hard saturation events that can damage FET switches. Ferrite cores offer lower core loss at frequencies above 2 MHz, but for converters running at 500 kHz to 1 MHz the powdered-iron construction provides a practical balance of saturation robustness and thermal stability from -40°C to +85°C.
