Category
The C21688786 is a through-hole inductor/transformer designed for noise filtering and signal conditioning in industrial, automotive, and renewable energy systems. Its 12-48V DC operation range and 0.5A current limit make it suitable for power supply applications, while extended use cases include motor control and high-frequency communication devices. Critical design parameters include maintaining proper soldering techniques, thermal management with 10mm heat dissipation spacing, and compliance testing for ±5% inductance tolerance. The product offers cost advantages in bulk purchases but faces stock availability challenges during peak demand periods.
