Category
The C21267210 surface mount inductor/transformer is optimized for cost-sensitive power management applications requiring ROHS compliance. Its 1.2A current rating and 85°C/W thermal performance make it suitable for consumer electronics and industrial motor control systems, but extended high-frequency use may require derating. Proper soldering techniques and thermal mitigation strategies are critical to maintain operational longevity.
