Active30,820 in stock
Overview
The SRU1048-100Y is a shielded drum core, wirewound inductor from Bourns designed for high-current power applications. It features a compact 10mm x 10mm footprint with a profile of approximately 4.8mm, offering a 10 uH inductance with a saturation current rating of 3.7A. The shielded construction helps minimize electromagnetic interference in dense circuit layouts.
Why Choose This Part
The component provides a balanced combination of a high 4.5A current rating and low 18.5mOhm DC resistance in a shielded package. Its ferrite core construction ensures stable performance across a wide temperature range of -40 to +125 degrees Celsius while containing magnetic flux to prevent interference with sensitive adjacent traces.
Applications
DC-DC Converters
Used as an energy storage element in buck, boost, and buck-boost topologies for local voltage regulation.
Input/Output Filtering
Acts as a low-pass filter component to reduce ripple current and EMI in power supply circuits.
Portable Electronics
Ideal for battery-powered devices requiring efficient power conversion in a low-profile surface mount package.
Distributed Power Systems
Suitable for point-of-load (POL) regulators in industrial and telecommunications equipment.
