SM4532-101MT 顺翔诺非屏蔽功率电感产品概述

一、产品基本定位与核心参数概览

SM4532-101MT是顺翔诺(SXN)推出的一款非屏蔽贴片功率电感,核心面向中小功率电子设备的电源管理、滤波及EMI抑制场景。其核心参数清晰明确:

  • 电感标称值:100uH(对应型号后缀“101”,即10×10¹μH);
  • 精度:±20%(满足常规应用的误差需求,无需额外校准);
  • 饱和电流(Isat):450mA(电感性能稳定的最大直流电流);
  • 直流电阻(DCR):1.52Ω(绕组的直流损耗参数);
  • 封装规格:SMD 4.5×4mm(行业通用4532封装,适配自动化贴装)。

二、关键性能指标的实际应用意义

1. 电感值与精度

100uH属于中低频段常用电感值,适配DC-DC转换、电源滤波等电路(如5V转3.3V的降压模块);±20%的精度兼顾成本与性能,适合消费电子、IoT设备等对精度要求不苛刻的场景,无需因校准增加额外成本。

2. 饱和电流(Isat)

450mA是该电感的“临界工作电流”——当直流电流超过此值时,磁芯会饱和,电感值骤降(通常下降≥30%),导致纹波增大、效率降低。实际应用中需确保负载电流≤450mA,避免性能失效。

3. 直流电阻(DCR)

1.52Ω的DCR是绕组的直流损耗指标,直接影响电路效率。以450mA工作电流计算,损耗功率约为0.31W(I²R=0.45²×1.52),属于同规格产品的常规水平,兼顾成本控制与损耗控制。

三、封装设计与适配性

采用SMD 4.5×4mm贴片封装,具备以下优势:

  • 小体积适配高密度PCB:适合智能穿戴(如手环、耳机)、小型家电等轻薄化设备,节省布局空间;
  • 标准化引脚设计:兼容主流贴片机(如富士、西门子系列)的吸嘴与贴装程序,无需额外调整,提升生产效率;
  • 非屏蔽设计的性价比:虽会产生少量电磁辐射,但在对EMI要求不高的场景下,比屏蔽电感成本降低15%-20%,适合中低端消费电子。

四、典型应用场景与价值

该电感主要覆盖三类场景:

1. 消费电子终端

  • 智能手机/平板:DC-DC降压模块的滤波电感(抑制纹波,提升电池续航);
  • 智能穿戴:手环、手表的电源管理电路(适配小尺寸PCB)。

2. IoT与智能家居

  • 蓝牙模块/传感器:EMI滤波(抑制信号干扰,提升传输稳定性);
  • 智能插座/加湿器:电源电路的储能电感(满足1-5W中小功率需求)。

3. 低要求汽车电子

  • 车载USB充电器:辅助滤波(适配车内有限空间,成本可控)。

五、可靠性与使用注意事项

顺翔诺对该产品完成常规可靠性测试(温度循环、振动测试),工作温度范围为**-40℃~+85℃**,满足大部分场景的环境要求。需注意:

  1. 禁止工作电流超过450mA,避免磁芯饱和;
  2. 非屏蔽设计不适合EMI严格场景(如医疗设备、高端通讯),需替换为屏蔽电感;
  3. 贴片焊接温度≤260℃(回流焊),避免损坏绕组绝缘层。

该产品以“小体积、高性价比、适配常规场景”为核心优势,是中小功率电子设备电源设计的常用选择。

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
