SM5845-471MT 非屏蔽功率电感产品概述

一、产品基本定位

SM5845-471MT是顺翔诺(SXN)品牌推出的SMD贴片式非屏蔽功率电感,属于中小功率电感范畴,主要面向消费电子、小型电源等对成本与尺寸有平衡需求的应用场景。该产品采用无磁屏蔽结构设计,兼顾电感性能与制造成本,是常规功率转换电路、滤波电路的实用选型。

二、核心电气参数详解

SM5845-471MT的核心电气参数明确且适配常规功率电路需求:

  • 标称电感值:470uH(产品标识“471”,对应“47×10¹=470uH”的电感量编码规则);
  • 电感精度:±20%,满足大部分消费类电子、小型电源对电感量偏差的容忍度,避免因电感量波动导致电路输出不稳定;
  • 类型属性:非屏蔽功率电感,无额外磁屏蔽层,结构简单,成本更低;
  • 封装尺寸:5.8×5.2mm(长×宽),SMD贴片封装,适配自动化贴装工艺。

注:直流电阻、额定饱和电流等关键功率参数需参考顺翔诺官方发布的产品规格书,以实际应用场景匹配为准。

三、物理特性与封装设计

1. 封装结构优势

SM5845-471MT采用表面贴装(SMD)封装,引脚设计贴合PCB焊接要求,支持回流焊、波峰焊等自动化生产工艺,可有效提升生产效率。5.8×5.2mm的小尺寸在PCB布局中占用空间少,适合便携设备、小型电源模块等对空间敏感的场景。

2. 非屏蔽结构特点

非屏蔽设计简化了电感的磁芯结构,降低了制造成本;同时,铁氧体磁芯(常见于该类产品)具备良好的高频特性,可支持中低频段(通常10kHz~1MHz)的功率转换与滤波需求。需注意:非屏蔽结构会产生一定电磁辐射,若应用场景对EMI(电磁干扰)要求较高,需配合屏蔽罩或选择屏蔽电感。

四、典型应用场景

SM5845-471MT的470uH电感量与功率特性,使其适配以下常见场景:

  1. DC-DC转换器:如降压型(Buck)、升压型(Boost)开关电源,用于储能与滤波,保障电压输出稳定;
  2. 电源滤波电路:在直流电源输出端或交流输入端,滤除纹波噪声,提升电源质量;
  3. LED驱动电路:中小功率LED照明的恒流/恒压驱动模块,配合电容实现平滑输出;
  4. 便携电子设备:笔记本电脑、平板、智能穿戴等设备的电源管理模块,兼顾尺寸与成本;
  5. 小型开关电源:如手机充电器、路由器电源等低功率电源产品的核心电感元件。

五、产品优势总结

  1. 成本效益平衡:非屏蔽结构降低了材料与制造成本,适合对成本敏感的消费类电子市场;
  2. 尺寸小巧易集成:5.8×5.2mm封装节省PCB空间,适配高密度布局需求;
  3. 电感性能稳定:±20%精度满足常规功率电路要求,避免因电感量偏差导致的电路性能波动;
  4. 生产兼容性强:SMD封装支持自动化贴装,适配主流电子制造工艺,降低生产难度。

六、使用注意事项

  1. 焊接工艺要求:需遵循顺翔诺推荐的回流焊温度曲线(通常峰值温度≤260℃,时间≤10秒),避免过热导致磁芯损坏或引脚脱落;
  2. 电流限制:实际工作电流不得超过产品额定饱和电流(参考规格书),否则电感会因磁饱和导致电感量急剧下降,影响电路性能;
  3. EMI考量:非屏蔽电感存在电磁辐射,若应用场景对EMI要求严格(如医疗设备、汽车电子),需增加屏蔽措施或更换屏蔽电感;
  4. 存储与运输:建议存储在温度-10℃~40℃、湿度≤60%的干燥环境,避免机械碰撞与潮湿侵蚀,防止引脚氧化或磁芯损伤。

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
