The Murata #A921CY-100M=P3 is a shielded surface-mount power inductor with an inductance of 10 µH and a tolerance of ±20%. It features a maximum DC current rating of 1.77 A, a saturation current of 1.14 A, and a maximum DC resistance of 49 mΩ. The component operates within a temperature range of -40°C to +85°C and utilizes a nonstandard package measuring approximately 6 mm x 6 mm x 3 mm.
This component is scheduled for obsolescence and will be discontinued by the manufacturer. Verify current availability through authorized distributors as stock may be limited. Confirm end-of-life status directly with Murata Electronics before finalizing procurement plans to avoid supply chain disruptions.
Select this part when a 10 µH shielded inductor is required for space-constrained designs. Ensure the 1.14 A saturation current meets peak load requirements. Consider the restricted operating temperature range (-40°C to +85°C) against environmental conditions. Evaluate alternative components if extended temperature ranges or higher current ratings are necessary.
The #A921CY series represents Murata's line of shielded power inductors designed for compact electronic applications. This specific model provides a balance of electrical performance and physical footprint suitable for modern surface-mount technologies. It belongs to the broader category of fixed inductors used in energy conversion and signal conditioning tasks.
Public confirmed substitute part numbers are not available in the provided documentation. Consult official Murata resources for recommended alternatives due to the product's obsolescence status.
