Category
The C21478718 is a surface-mount inductor accessory designed for EMI filtering and power management in consumer electronics, telecom, and automotive applications. It operates within 0.5A/100V limits with thermal management requiring heat sinking. ROHS compliance and bulk pricing make it suitable for high-volume designs but demands datasheet verification for precise parametric matching.
