Category
The C21945972 ferrite inductor/transformer is a compact surface mount component designed for power supply filtering and signal management in industrial automation, renewable energy systems, and communication infrastructure. Its ROHS-compliant construction supports high-frequency operation with stable inductance tolerance (±5%) and thermal performance up to 85℃. Critical design parameters include maintaining soldering temperatures below 350℃ and ensuring proper heat dissipation through thermal vias in high-power applications. The component's 0.5A continuous current rating and 100VDC operating voltage limit make it suitable for intermediate power stages while requiring careful thermal management in dense PCB layouts.
