What are the key features of 74437346068?
- 6.8µH nominal inductance with only 0.06Ω DC resistance for low power loss in high-current switching converter stages
- Powdered iron core construction in compact 2926 rectangular case provides excellent saturation current handling and minimal EMI
- General purpose power inductor design compatible with buck, boost, and SEPIC converter topologies operating at standard switching frequencies
What is 74437346068 used for?
The Würth Elektronik 74437346068 is suited for use as the energy storage inductor in step-down (buck) and step-up (boost) DC-DC converters in embedded systems, industrial power supplies, and point-of-load regulators. Its 6.8µH inductance and low 0.06Ω DCR make it ideal for high-efficiency power stages operating at 200kHz to 1MHz switching frequencies with output currents in the 1A to 5A range. It is also applicable in filter chokes and energy storage circuits where a compact 2926-size SMT footprint is required.

Frequently Asked Questions
What is the inductance value and DC resistance of the Würth 74437346068 power inductor?
The 74437346068 has a nominal inductance of 6.8µH and a DC resistance of 0.06Ω. This low DCR value minimizes conduction losses in high-current applications, making it well suited for buck converter output stages carrying 2A to 5A of continuous load current at switching frequencies between 200kHz and 1MHz.
How does powdered iron core construction in the 74437346068 benefit switching regulator performance compared to ferrite-core alternatives?
Powdered iron cores exhibit a soft saturation characteristic, meaning inductance degrades gradually as current increases rather than abruptly as with ferrite cores. This makes the 74437346068 more tolerant of current spikes in buck-boost converters and reduces the risk of inductor saturation at peak currents above the rated value, improving robustness in 5V to 24V power supply designs.
Which DC-DC converter topologies are compatible with the Würth 74437346068 6.8µH inductor?
The 74437346068 is compatible with synchronous buck, asynchronous boost, SEPIC, and flyback converter topologies requiring a 6.8µH energy storage element. Its 2926 rectangular SMT case fits standard footprints used by controllers from Texas Instruments, Monolithic Power Systems, and Maxim for converters with 1A to 10A output current ratings and switching frequencies up to 1MHz.
For a 12V-to-5V buck converter PCB, does the 2926 case size of the 74437346068 offer a space advantage?
Yes. The 2926 case (approximately 7.3mm x 6.6mm footprint) is a compact through-hole or SMT size that fits efficiently on standard 4-layer power PCBs. Compared to larger 3838 or 4040 inductors with similar 6.8µH ratings, the 2926 case reduces inductor board area by roughly 30%, freeing space for input/output capacitors and control circuitry in the same power stage layout.
