Overview
The #B953AS-221M=P3 is a shielded power inductor from the DS126C2 series, manufactured by Murata Electronics. It features a ferrite drum core and wirewound construction within a 4949 (12.5mm x 12.5mm) surface-mount package with a maximum height of 6.8mm. The component provides an inductance of 220 µH with a ±20% tolerance. It supports a maximum DC current of 1 A and reaches saturation at 1 A. The maximum DC resistance is 350 mOhms. It operates between -40°C and +85°C.
Feature Summary
- Shielded wirewound design utilizing a ferrite drum core to minimize electromagnetic interference.
- Compact 4949 surface-mount footprint suitable for space-constrained PCB layouts.
- High saturation current rating matching the maximum DC current limit.
Applications
- Power line choke applications
- DC-DC converter input/output filtering
- General-purpose power supply circuits
Procurement Notes
Verify component status carefully as this part is scheduled for obsolescence and will be discontinued by the manufacturer. Confirm availability through authorized distributors or check for alternative sourcing options due to potential limited stock. Ensure final designs account for end-of-life timelines to prevent future supply chain disruptions.
Selection Notes
Select this component when a shielded SMD inductor with 220 µH nominal value is required. Verify that the 1 A current rating meets circuit requirements. Consider the 4949 package dimensions for board space. Note the restricted operating temperature range up to 85°C. Evaluate obsolescence risks before finalizing the bill of materials.
Part Context
This part belongs to the B953AS series of power inductors designed for general electronic equipment. It is distinct from RF inductors like the LQH55DN series due to its lower self-resonant frequency characteristics and higher current handling capabilities typical of power chokes.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, consult Murata for recommended alternatives or perform a full parameter match search for compatible shielded power inductors.
