Frequently Asked Questions
What inductance value and DC resistance does the Würth 74437349010 provide for DC-DC converter designs?
The 74437349010 offers a nominal inductance of 1 µH and an extremely low DC resistance of 0.0065 Ω (6.5 mΩ). This ultra-low DCR minimizes I²R conduction losses at high load currents, making it well suited for high-efficiency synchronous buck converters, point-of-load regulators, and multiphase power stages in server and industrial power supplies.
How does the powdered iron core material of the 74437349010 benefit high-current power supply designs?
Powdered iron cores exhibit a soft saturation characteristic, meaning inductance decreases gradually rather than sharply as DC bias current increases. This behavior prevents sudden efficiency drops in DC-DC converters operating at high load currents, making the 74437349010's 1 µH powdered iron design more tolerant of current spikes compared to ferrite-core inductors with abrupt saturation in switching power supply applications.
For which switching frequencies and output current levels is the 74437349010 inductor best optimized?
The 74437349010's 1 µH inductance in the 2926 case is optimized for switching frequencies typically in the range of 200 kHz to 2 MHz, where the inductance provides suitable ripple current attenuation in buck and boost topologies. Its low 6.5 mΩ DCR supports continuous load currents of several amperes with minimal self-heating, depending on ambient temperature and PCB thermal design.
How does the 2926 SMT case size of the 74437349010 compare to larger power inductor packages for board space-constrained designs?
The 2926 case measures approximately 7.3 mm × 6.6 mm footprint, which is a mid-range power inductor size. Compared to larger 3030 or 3050 case sizes, the 2926 offers a smaller PCB footprint while still supporting multi-ampere current ratings, making it a practical choice for dense power stage layouts in compact industrial controllers, wireless routers, and embedded single-board computers.
