Frequently Asked Questions
What inductance value and DC resistance does the SRR3818A-1R0Y offer for power converter designs?
The SRR3818A-1R0Y provides 1 µH nominal inductance and a DC resistance of only 0.037 ohms. The low DCR minimizes I²R conduction losses in switch-mode power supply inductors, supporting efficient energy transfer in buck and boost converters at switching frequencies above 1 MHz.
Which DC-DC converter topologies is SRR3818A-1R0Y suitable for, given its 1 µH inductance?
A 1 µH ferrite inductor like the SRR3818A-1R0Y suits high-frequency buck, boost, and SEPIC converters typically switching between 500 kHz and 5 MHz. At these frequencies, 1 µH maintains acceptable ripple current without excessive physical size, making it a standard choice for point-of-load regulators in mobile, IoT, and telecom power supplies.
How does the 1515 case size of SRR3818A-1R0Y affect PCB layout options compared to larger power inductors?
The 1515 case code corresponds to approximately 3.8 mm × 3.8 mm footprint, notably smaller than common 4040 or 5050 power inductors. This compact footprint reduces PCB area consumed by the inductor by roughly 50% compared to a 4040 package, freeing space for filter capacitors and control ICs in dense point-of-load converter designs.
