SMMS06030-470MT 功率电感产品概述

一、产品基本定位与核心参数

SMMS06030-470MT是顺翔诺(SXN)推出的贴片式功率电感,针对中小功率电源电路的滤波、储能需求设计,兼顾紧凑尺寸与稳定性能。核心参数明确:

  • 电感标称值:47μH,精度±20%(实际范围37.6μH~56.4μH);
  • 电流特性:额定连续电流1.1A,饱和电流(Isat)2A;
  • 直流电阻(DCR):385mΩ;
  • 封装规格:SMD贴片,尺寸7.1×6.6×3mm(长×宽×高)。

二、关键性能指标详解

1. 电感值与精度

47μH的标称值覆盖多数电源电路的滤波需求(如DC-DC转换、EMI抑制),±20%的精度符合工业级功率电感的通用标准,无需额外校准即可满足常规应用;若对电感值精度要求更高(如射频电路),需结合具体场景预留裕量。

2. 电流特性的实际意义

  • 额定电流(1.1A):指电感连续工作时,内部温升不超过行业标准(通常≤20℃)的最大电流,长期工作需控制电流在此范围内,避免过热导致性能衰减;
  • 饱和电流(2A):指电感值下降30%时的峰值电流(磁芯饱和阈值),设计时需确保电路峰值电流不超过2A,否则会出现电感值突变,影响电源稳定性。

3. 直流电阻与损耗

385mΩ的DCR是电感直流损耗的核心来源,1.1A连续电流下的损耗为I²R=1.1²×0.385≈0.465W,温升可控;若需进一步降低损耗,可搭配低内阻电源或并联小容量电容,但需注意电感值匹配。

4. 封装尺寸的适配性

7.1×6.6×3mm的紧凑尺寸属于小型贴片电感,兼容常规SMT产线(回流焊、波峰焊),适合便携设备(如手机、平板)、小型家电(充电器、机顶盒)的高密度PCB设计,无需额外占用大空间。

三、典型应用场景

SMMS06030-470MT的性能匹配多类中小功率电路,核心应用包括:

  1. 消费电子电源:手机/平板的PMIC滤波、无线充接收端储能;
  2. 小型家电:5V/1A充电器、路由器DC-DC转换电路;
  3. 物联网设备:低功耗传感器节点的电源管理模块;
  4. 工业辅助电路:小型PLC、电机驱动的低电压辅助电源。

其贴片封装与低损耗特性,尤其适合对空间和效率要求高的便携/紧凑场景。

四、品牌与可靠性说明

顺翔诺(SXN)作为国内专业电感制造商,该产品经过多项可靠性测试,确保恶劣环境下的稳定性:

  • 温度循环:-40℃~+85℃,循环500次,无参数漂移;
  • 湿度测试:85℃/85%RH环境48小时,DCR变化≤5%;
  • 振动测试:10~2000Hz振动(加速度1g),持续2小时,无脱落/虚焊;
  • 焊接兼容性:回流焊温度曲线(峰值245℃)下,焊盘无氧化、电感无变形。

这些测试覆盖了多数应用场景的环境要求,适合量产级产品的可靠性需求。

五、选型参考要点

  1. 电流匹配:连续工作电流≤1.1A,峰值电流≤2A(若峰值电流接近2A,需预留10%~15%裕量);
  2. 电感值需求:若电路需精确电感值,可通过并联/串联调整,但需注意功率损耗;
  3. 空间限制:确认PCB焊盘尺寸(通常对应0630封装的焊盘布局),避免尺寸冲突;
  4. 效率要求:若电源效率要求≥95%,需计算电感损耗占比(如1A电流下损耗0.385W,占1W输出的3.85%,需结合其他元件损耗评估)。

综上,SMMS06030-470MT是一款性价比高、适配性强的小型功率电感,适合多数中小功率电源电路的量产应用,兼顾尺寸、性能与可靠性。

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
