Frequently Asked Questions
What inductance and DCR does the 74437346056 provide for switching regulator output filter design?
The 74437346056 provides 5.6 µH nominal inductance with a DC resistance of 0.048 Ω. In a 12 V to 5 V buck converter at 5 A output, this combination limits conduction loss to approximately 12 mW and sets the ripple current to a controllable range at switching frequencies between 200 kHz and 1 MHz.
How does the powdered iron core of the 74437346056 benefit high-current power converter designs compared to ferrite cores?
Powdered iron cores exhibit a gradual, soft saturation characteristic compared to the hard saturation of ferrite cores. The 74437346056's powdered iron core maintains inductance more linearly as current increases, preventing abrupt duty cycle changes and protecting switching regulators from peak current faults at output load currents above 5 A.
What 2926 case dimensions does the 74437346056 occupy on a PCB, and how does this compare to smaller inductor packages?
The 2926 case measures approximately 7.3 mm × 6.7 mm, offering a larger footprint than 1210 or 1812 inductors but providing proportionally higher saturation current capacity and lower DCR of 0.048 Ω. This trade-off is appropriate for point-of-load converters delivering 3 A to 8 A where a compact 2520 inductor's higher DCR would exceed thermal budgets.
