Category
The C21122411 magnetic component is a compact ROHS-compliant inductor designed for filtering and noise suppression in consumer and industrial electronics. With a current limit of 1.2A and voltage operation up to 48VDC, it suits power supplies and control systems while requiring careful thermal management at 60°C/W thermal resistance. Extended applications include automotive and medical devices when paired with proper layout practices, though it lacks extreme temperature tolerance and mandates minimum order quantities for cost efficiency.
