#B953AS-270M=P3

Overview

The #B953AS-270M=P3 is a shielded drum core, wirewound fixed inductor manufactured by Murata Electronics. It features an inductance of 27 µH with a tolerance of ±20%, tested at a frequency of 100 kHz (0.1 MHz). The component has a maximum DC resistance of 50 mΩ and a rated current of 2.8 A for temperature rise, with a saturation current of 3.2 A. It utilizes a nonstandard surface-mount package measuring 12.80 mm x 12.80 mm in footprint and 6.80 mm in maximum height. The device operates within a temperature range of -40°C to 85°C.

Feature Summary

Shielded drum core construction minimizes electromagnetic interference
High saturation current capability supports demanding power applications
Low DC resistance enhances energy efficiency

Applications

DC-DC converter output filtering
Power supply input stages
General-purpose power electronics

Procurement Notes

This component is scheduled for obsolescence and will be discontinued by the manufacturer. Verification of end-of-life status and final shipment availability is required before procurement. Alternative components should be evaluated immediately to ensure supply chain continuity. Confirm specific suffix requirements with the manufacturer as packaging or minor specifications may vary during the transition period.

Selection Notes

Select this inductor when a 27 µH value with high current handling is required in a compact surface-mount form factor. The 2.8 A rated current and 3.2 A saturation current make it suitable for moderate-power applications. Ensure the nonstandard package dimensions fit the PCB layout constraints. Consider the operating temperature range and shielding requirements for the specific environment.

Part Context

The B953AS series represents Murata's line of shielded drum core wirewound inductors designed for power management applications. These components are characterized by their robust construction and ability to handle significant current levels while maintaining low DC resistance. The series offers various inductance values to suit different circuit requirements.
