Category
The C20699434 magnetic component is a cost-effective inductor/transformer accessory designed for power electronics and communication systems. Its ±5% tolerance and 100V rating make it suitable for filtering in switching supplies while extended applications include 5G modules and automotive systems. Proper thermal management and soldering techniques are critical to maintain 40°C/W thermal performance. The RoHS compliance and industrial-grade reliability position it for mass production but limited stock availability may impact large-scale projects.
