Category
The C21872618 is a cost-effective surface-mounted inductor designed for power supply filtering and noise suppression in consumer electronics and automotive systems. Its ±5% tolerance and 100V operating range make it suitable for medium-current applications, while thermal management requires careful PCB layout to maintain performance at elevated temperatures. The component's Rohs compliance supports medical and automotive certifications but lacks high-frequency capabilities beyond 50MHz.
