0077193A7
Category
The Magnetics 0077193A7 is a surface-mount inductor optimized for power electronics applications, providing stable filtering in DC-DC converters and motor control systems. Its 12-48V operation range and 0.5A continuous current capability make it suitable for industrial IoT devices and renewable energy systems. Proper thermal management and ESD protection are critical during soldering and assembly to maintain 60°C/W thermal performance. While cost-effective at bulk quantities, its limited frequency response restricts use in high-frequency RF applications.
