Category
The C22166233 is a compact ferrite inductor optimized for EMI filtering and signal management in high-frequency electronics, particularly suitable for IoT devices and renewable energy systems. Its ROHS-compliant design supports 12-48V operations with 0.5A continuous current handling, requiring careful thermal management at temperatures above 85°C. The component's 5% inductance tolerance and 100MHz+ self-resonant frequency make it ideal for noise suppression in switched-mode power supplies, though its 50mΩ DC resistance limits high-current applications. Engineers should prioritize layout spacing and derating under extended temperature conditions.
