Category
The C21066880 is a cost-effective surface-mount inductor designed for basic filtering and EMI suppression in consumer electronics, automotive, and industrial applications. Its compact 0077030AY package supports reliable soldering at controlled temperatures while maintaining compliance with ROHS standards. The component's ±5% tolerance and 0.5A current rating make it suitable for noise reduction in power supplies and sensor circuits, though extended use in high-frequency (>100MHz) or high-temperature environments requires careful thermal management.
