Category
The C20847857 is a cost-effective surface-mount inductor/transformer designed for general-purpose filtering and coupling applications. It features RoHS-compliant construction with a 0.001kg weight and 100V operational voltage, making it suitable for power supply filtering and RF circuits. Designers should prioritize proper thermal management (85℃/W thermal resistance) and avoid static discharge risks. While offering good stock availability and surface-mount compatibility, its performance limitations at high frequencies and moderate thermal cycling tolerance require careful consideration in extended temperature environments.
