Frequently Asked Questions
What are the key electrical specifications of the NRS4012T4R7MDGJ inductor?
The NRS4012T4R7MDGJ offers a nominal inductance of 4.7 µH with a DC resistance of 0.114 Ω. This low DCR supports efficient power delivery in switching regulators, minimizing power loss at rated current and keeping operating temperatures low in compact power supply designs.
Which DC-DC converter topologies benefit most from using the NRS4012T4R7MDGJ at its 4.7 µH value?
Buck and boost converters operating at 1 MHz to 3 MHz switching frequencies benefit most from the 4.7 µH inductance of the NRS4012T4R7MDGJ, as this value provides adequate energy storage and output ripple suppression while keeping the 1616 package small enough for wearable and portable device PCBs.
How does the 1616 case size of the NRS4012T4R7MDGJ compare to larger SMD inductors for power applications?
The 1616 case size (4.0 x 4.0 mm footprint and 1.2 mm height) of the NRS4012T4R7MDGJ is significantly smaller than common 2520 or 3225 power inductors, making it preferable when board space is critical, though designers should verify the saturation current rating meets the application's peak load current requirements.
