Category
The C21547878 magnetic component is a surface-mount inductor optimized for high-frequency signal processing in consumer electronics and industrial automation systems. Its compact 0077120A7HT14 package supports continuous operation up to 100V with 0.5A current handling, making it suitable for power supply filtering and RF matching. Designers should prioritize proper thermal management through copper layer enhancement and maintain static safety protocols during assembly. While cost-effective for mass production, extended temperature operation requires additional protection measures.
