Overview
The B82731H2901A030 is a shielded power inductor from the B82731 series, designed for high-current applications in DC-DC converters. It features a ferrite core with a silver-plated copper wire winding and a magnetic shield to minimize electromagnetic interference. The component offers an inductance of 900 µH with a tolerance of ±20%. Rated for a saturation current of 3.0 A and a thermal current of 2.5 A, it operates within a temperature range of -40°C to +125°C. The device utilizes a surface-mount package suitable for automated assembly processes.
Feature Summary
- Integrated magnetic shielding reduces external electromagnetic interference and crosstalk between adjacent components on the circuit board.
- Robust construction supports high saturation currents, maintaining performance under heavy load conditions typical in power supply circuits.
- Surface-mount design facilitates efficient PCB layout and automated manufacturing integration.
Applications
- DC-DC converter output filtering
- Point-of-load regulation stages
- Power management modules in industrial equipment
Procurement Notes
Verify the complete part number against official EPCOS-TDK datasheets to ensure correct inductance value and current ratings. Confirm that the specified tolerance and operating temperature range align with your system requirements. Check for any specific handling or storage instructions provided in the manufacturer's documentation before procurement.
Selection Notes
Select this component based on its 900 µH inductance and 3.0 A saturation current capability. Ensure the physical dimensions fit the designated footprint on the printed circuit board. Consider the thermal performance and ambient operating conditions to guarantee reliability within the specified -40°C to +125°C range during continuous operation.
Part Context
This component belongs to the B82731 series of shielded power inductors manufactured by EPCOS, now part of TDK Electronics. The series is engineered for demanding power electronics applications requiring compact size and high efficiency. These inductors are widely used in automotive and industrial sectors where space constraints and electromagnetic compatibility are critical design factors.
Replacement Considerations
Consult official cross-reference lists from EPCOS-TDK for verified substitutes. Ensure any replacement matches the 900 µH inductance, 3.0 A saturation current, and compatible package dimensions. Verify that alternative components meet the same thermal and electrical specifications for direct interchangeability.
