概述

Description

SPM6550T-4R7M is a surface-mount power inductor in the SPM family. It provides an inductance of 4.7 µH (4R7) with tolerance M (typically ±20%). The 6550 usually indicates a 6.5×5.0 mm footprint; the T often denotes tape-and-reel packaging. It’s designed for high-current DC-DC converter use, offering low DCR and good saturation/thermal performance to support VRMs, buck/boost converters, and other power‑rail applications. For exact specs (DCR, rated current, saturation current, temperature range, and packaging details), consult the manufacturer’s datasheet or distributor listing for SPM6550T-4R7M.
