#A921CY-120M=P3

Overview

The #A921CY-120M=P3 is a shielded surface-mount power inductor manufactured by Murata Electronics. It features an inductance of 12 µH with a tolerance of ±20%. The component has a maximum DC current rating of 1.8 A and a saturation current of 1.04 A. Its maximum DC resistance is 63 mΩ. The device operates within a temperature range of -40°C to +85°C and utilizes a 2524 (6362 metric) package.

Feature Summary

Shielded wirewound construction for electromagnetic interference reduction
Surface-mount design compatible with automated assembly processes
High current handling capability with defined saturation limits

Applications

Line choke applications in power supply circuits
DC-DC converter output filtering
General-purpose power electronics signal conditioning

Procurement Notes

This component is scheduled for obsolescence and will be discontinued by the manufacturer. Availability may be limited or restricted depending on regional distribution channels. Verify end-of-life status and final order dates through official Murata Electronics documentation before procurement planning. Ensure compliance with lifecycle management policies when integrating this part into long-term production designs.

Selection Notes

Select this inductor for applications requiring a 12 µH value with moderate current handling up to 1.8 A. Consider the 2524 footprint for board space constraints. Evaluate thermal performance at operating temperatures between -40°C and +85°C. Confirm that the saturation current of 1.04 A meets peak load requirements to prevent inductance degradation during transient conditions.

Part Context
