Category
The C21761719 is a cost-effective ROHS-compliant inductor designed for general-purpose filtering and EMI suppression in consumer electronics and IoT devices. It features a surface-mount package optimized for automated assembly with thermal resistance of 35°C/W, operational up to 100VDC/AC, and 0.5A continuous current. While suitable for basic power supply filtering and communication device EMI suppression, engineers should verify performance in high-frequency applications and avoid static discharge risks during handling.
