Frequently Asked Questions
What inductance value and DC resistance does the Bourns SDR1005-100ML provide?
The SDR1005-100ML has a nominal inductance of 10 µH and a DC resistance of 0.05 Ω, making it efficient for power conversion applications where minimizing conduction losses is important for overall circuit efficiency.
Which DC-DC converter topologies benefit most from the SDR1005-100ML's ferrite core and 10 µH inductance?
Synchronous buck and boost converters switching at frequencies between 200 kHz and 2 MHz benefit from the SDR1005-100ML's 10 µH ferrite inductance, as it provides adequate energy storage and low core loss to achieve output ripple below 50 mV in typical 5 V and 12 V power rails.
How does the 5039 SMD package of SDR1005-100ML affect PCB layout in compact power designs?
The 5039 rectangular case (approximately 5.0 × 3.9 mm footprint) allows the SDR1005-100ML to be placed close to switching FETs on standard 2-layer PCBs, reducing high-frequency current loop area and limiting EMI radiation in power stages operating at switching frequencies up to 2 MHz.
What lead time and lifecycle status should procurement teams expect when ordering SDR1005-100ML in volume?
Bourns lists a factory lead time of 14 weeks for the SDR1005-100ML, which is typical for ferrite SMD power inductors. Procurement teams designing new products should secure buffer stock or qualify an alternative 10 µH, 0.05 Ω inductor in the same 5039 footprint to mitigate supply risk during peak demand periods.
