Category
The C21478734 is a compact inductor/transformer accessory optimized for power electronics and signal processing applications. Its surface mount design supports automated assembly while maintaining robust performance across 12-48V DC ranges. Key features include ESD protection, RoHS compliance, and thermal stability up to 85℃. Ideal for DC-DC converters and renewable energy systems requiring compact filtering solutions, though designers should pay attention to static handling and verify surge tolerance in high-stress environments.
