SMMS0650-1R5M功率电感产品概述

SMMS0650-1R5M是顺翔诺(SXN)推出的贴片式功率电感,专为中高功率电子电路的储能与滤波需求设计,兼具高电流承载、低损耗及紧凑封装等特点,广泛适配各类电源及功率转换场景。

一、产品基本信息

该型号属于功率电感范畴,型号命名逻辑清晰:SMMS为品牌/系列标识,0650对应封装尺寸(7.1×6.6×5mm),1R5表示电感值1.5μH(“R”替代小数点),M代表精度±20%。产品采用表面贴装(SMD)工艺,支持自动化生产,适配高密度PCB布局。

二、核心电气参数详解

1. 电感值与精度

标称电感值1.5μH,精度±20%,实际范围1.2μH~1.8μH。此精度满足功率电感典型需求——功率电路中电感以储能、滤波为主,无需高频谐振级精度,±20%范围可降低成本且不影响电路效率。

2. 电流承载能力

  • 额定电流(Iₐ):10A,指25℃环境下连续工作时,磁芯、线圈不超温的最大电流,稳定工作于10A以内可长期可靠运行;
  • 饱和电流(Iₛₐₜ):12.7A,磁芯饱和临界电流。超过此值磁导率下降,电感值快速跌落(通常降至70%以下),可能导致输出波动。12.7A比额定电流高27%,可应对启动、负载突变等峰值场景。

3. 直流电阻(DCR)

DCR为8.5mΩ,是线圈导线直流电阻。低DCR是核心优势:10A电流下损耗P=I²R=10²×8.5×10⁻³=0.85W,发热小,降低散热设计要求。

三、封装与物理特性

采用SMD贴片封装,外形尺寸7.1mm(长)×6.6mm(宽)×5mm(高),体积紧凑适配中功率电路PCB布局。封装材料耐高温,可承受回流焊温度冲击,引脚牢固焊接可靠性高。

四、典型应用场景

  1. DC-DC转换器:车载降压模块(中控、车灯供电)、工业开关电源(12V/10A输出);
  2. 电源模块:服务器电源、笔记本适配器次级滤波;
  3. LED驱动:大功率显示屏、路灯驱动恒流/恒压电路;
  4. 工业控制:PLC、伺服驱动器辅助电源滤波;
  5. 消费电子:高容量移动电源、户外电源升压/降压电路。

五、性能优势分析

  1. 高电流稳定性:饱和电流远高于额定电流,峰值场景电感跌落少,输出更稳定;
  2. 低损耗低发热:8.5mΩ DCR降低线圈损耗,减少散热空间需求;
  3. 紧凑适配性:7.1×6.6mm尺寸适合小型化设备(车载、便携式电源);
  4. 工艺兼容性:贴片封装支持自动化生产,提升效率;
  5. 宽温适用:-40℃~+125℃工作范围,适配车载、工业严苛环境。

六、选型参考要点

  1. 电流匹配:工作电流≤10A,峰值≤12.7A,避免饱和或超温;
  2. 电感验证:精密滤波场景需确认实际值在1.2μH~1.8μH范围内;
  3. 封装兼容:检查PCB是否匹配7.1×6.6×5mm尺寸;
  4. 散热设计:10A电流下0.85W损耗,需预留散热铜箔;
  5. 温度降额:环境超25℃时,每升10℃额定电流降额10%左右。

总结:SMMS0650-1R5M平衡了电流承载、损耗与体积,是车载、工业、消费电子领域中高功率场景的可靠选择,性价比突出。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
