Power Bead Inductor

Product Description

The Power Bead Inductor HCB series delivers exceptional performance in power management systems. Engineered for high-current applications, these inductors feature ultra-low core losses (tested at 100kHz) and robust ferrite materials. With inductance ranging from 22nH to 680nH and current handling up to 110A, they optimize energy transfer in modern electronics. Ideal as a Power Inductor for voltage regulation, their shielded design minimizes EMI interference in sensitive circuits.
