Category
The Magnetics 0079894A7 is a compact inductor/transformer accessory optimized for EMI filtering and power supply stabilization in consumer electronics, automotive systems, and medical devices. Its 24-48V DC operation range and 500mA current handling make it suitable for signal conditioning in communication modules, while its ROHS compliance ensures regulatory compliance. Designers should prioritize proper thermal management and spacing to maximize performance, though its frequency limitations suggest pairing with external filters for high-frequency applications.
