Category
This magnetic component is a cost-effective ROHS-compliant inductor/transformer designed for power supply filtering and RF applications. It operates within 12-48V DC with a 0.5A current limit, requiring careful thermal management at up to 85°C. Best suited for high-frequency communication devices and automotive control units when ordered in bulk quantities, but lacks detailed parametric data and immediate stock availability.
