SMMS0630-4R7M是顺翔诺(SXN)推出的一款SMD表贴式一体成型功率电感,针对中功率电子设备的电源电路设计,兼顾高密度布局、低损耗与高可靠性,是开关电源、LED驱动、移动设备电源管理等场景的实用选择。
该产品属于顺翔诺SMMS0630系列,以“小尺寸承载大电流”为设计核心,适配当前电子设备“轻薄化、集成化”趋势。其封装尺寸(7.3×6.6×3mm)符合主流SMD贴装标准,可直接兼容多数自动化生产流程,无需额外调整产线。
额定电感值为4.7μH,精度±20%——这一精度范围在功率电感应用中属于常规且可靠的区间,能满足多数电源电路对电感值的稳定需求,避免因精度偏差导致的输出波动。
饱和电流(Isat)达6.55A:饱和电流是电感值下降30%时的临界电流,直接决定电感的最大负载能力。6.55A的设计可覆盖多数中功率场景(如10-50W电源模块),即使短期过载也能保持基本电感特性,减少电路故障风险。
直流电阻(DCR)仅40mΩ:低DCR是降低铜损的核心——铜损(I²×R)是功率电感的主要损耗来源之一,40mΩ的DCR可显著减少发热,提升电源转换效率(大电流场景下效率提升可达2-3%)。
采用7.3×6.6×3mm SMD表贴封装,属于行业“0630”系列(前两位为宽度、后两位为长度,单位0.1mm),尺寸紧凑,适合高密度PCB布局(如笔记本主板、小型电源模块)。
SMMS0630-4R7M采用一体成型磁芯结构,相比传统绕线电感有明显优势:
该产品性能与尺寸适配多种中功率电子场景:
若需替代,可优先考虑同参数SMD电感:
SMMS0630-4R7M通过平衡尺寸、电流、损耗与可靠性,成为中功率电源电路的高性价比选择,可满足多数消费电子与工业设备的设计需求。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
