FAE Expert Insights
"The CL-PI-100-4R7 is my standard recommendation for 10-20A buck converters. The 4.7μH hits the sweet spot for 300-500kHz switching frequency - good ripple current without excessive DCR loss. The 3.5mΩ DCR means only 0.35W loss at 10A, keeping efficiency high. The shielding is effective - I've never had EMI issues with this series. AEC-Q200 qualification makes it suitable for automotive applications. One tip: the thermal rating is conservative - you can run higher current with good PCB copper area for heat sinking. For higher current, the CL-PI-130 series offers 15A+ capability. Overall excellent value for the performance."
