Frequently Asked Questions
What inductance and DC resistance does the SRN6045TA-1R0Y provide for power converter designs?
The SRN6045TA-1R0Y provides 1 µH nominal inductance with an ultra-low DC resistance of only 10 mΩ. This combination enables efficient high-current power conversion with minimal resistive loss, making it suitable for DC-DC buck converter output filters in high-performance computing and portable electronics applications.
Which converter topologies and switching frequencies are compatible with the SRN6045TA-1R0Y?
The SRN6045TA-1R0Y works effectively in buck, boost, and SEPIC DC-DC converter topologies. Its 1 µH ferrite-core construction supports switching frequencies ranging from hundreds of kHz to several MHz, making it a good fit for modern synchronous buck regulators powering CPU cores, FPGAs, and point-of-load power rails in embedded systems.
What does the shielded construction of the SRN6045TA-1R0Y offer compared to unshielded inductors?
The SRN6045TA-1R0Y uses a ferrite shielded construction in a 6.0x6.0x4.5 mm package, which significantly reduces radiated electromagnetic emissions compared to unshielded inductors. This allows placement closer to noise-sensitive analog and RF circuits on the PCB, simplifying EMI compliance for consumer electronics and industrial power designs at 1 µH inductance.
How does the SRN6045TA-1R0Y package size affect PCB layout in compact power designs?
The SRN6045TA-1R0Y occupies a 6.0x6.0 mm footprint with 4.5 mm height, a mid-size profile that balances inductance density and board area in power supply layouts. At 1 µH and 10 mΩ DCR, it delivers high current capacity in a standardized 2424 case code, fitting alongside compact MOSFET drivers and control ICs on dense multi-layer power PCBs.
