Frequently Asked Questions
How does SRP7030CA-3R3M's 0.018 Ω DCR benefit switching converter efficiency?
The SRP7030CA-3R3M has a DC resistance of only 0.018 Ω, which minimizes I²R power losses in the inductor when carrying high currents. In a 5 A switching converter, for example, this low DCR results in less than 0.5 W of conduction loss, directly improving overall converter efficiency compared to inductors with higher DCR values.
What DC-DC converter topologies are most suitable for the 3.3 µH SRP7030CA-3R3M?
SRP7030CA-3R3M with its 3.3 µH inductance and low 0.018 Ω DCR is well matched to synchronous buck and boost converter designs operating at 300 kHz to 2 MHz switching frequencies. These topologies are common in CPU power delivery, battery management, and point-of-load regulators in industrial and computing equipment.
What is the footprint of the SRP7030CA-3R3M and how does it compare to larger power inductor packages?
SRP7030CA-3R3M uses Bourns' 3130 case size, measuring approximately 7.3 mm × 6.6 mm with a rectangular SMD footprint. This is more compact than larger 10 x 10 mm inductor packages, allowing it to fit in tight power stages where board area is limited while still providing the 3.3 µH inductance needed for typical DC-DC designs.
What are the lead time and stock planning considerations for SRP7030CA-3R3M in a production build?
SRP7030CA-3R3M typically has a factory lead time of 14 weeks, which is common for Bourns specialty power inductors. Procurement teams planning production runs should schedule orders well in advance and consider safety stock of at least 4 to 8 weeks of supply to avoid line stoppages during demand spikes or supply chain disruptions.
