Category
The C22019220 surface mount inductor/transformer accessory provides reliable magnetic filtering and coupling in consumer electronics and industrial power systems. Its ROHS-compliant ferrite core design supports 1.2A continuous current with 500V voltage handling, making it suitable for renewable energy inverters and IoT power modules. Critical design parameters include maintaining 85℃/W thermal resistance and ensuring 10mm PCB spacing for optimal performance. While cost-effective at bulk quantities, stock availability and industrial temperature range represent current limitations.
