Category
The C22019198 surface-mount inductor is optimized for EMI filtering and power management in consumer electronics and IoT devices. Its compact 0402 package enables space-efficient designs while maintaining basic filtering capabilities up to 1MHz. Engineers should prioritize proper thermal management and verify current/voltage limits through iterative testing, particularly in automotive and renewable energy applications where extended operating conditions are common.
