SM4532-680MT 功率电感产品概述

一、产品基本定位与核心价值

SM4532-680MT是顺翔诺(SXN)推出的一款小尺寸表面贴装(SMD)非屏蔽功率电感,核心定位为低电流、小型化电子设备的储能与滤波组件。其设计平衡了电感性能、封装尺寸与成本,适合对空间敏感但无需极高电磁干扰(EMI)抑制的场景,是便携式电子、物联网终端等领域的经济型实用选型。

二、关键参数详细解析

SM4532-680MT的参数聚焦小电流场景,核心参数需重点关注:

  1. 电感值与精度:标称68μH,精度±20%。该精度满足大多数常规电源电路(如DC-DC转换、滤波)的需求,无需额外高精度校准,降低系统设计复杂度;
  2. 电流承载能力:
    • 额定电流(I₍rms₎):370mA(行业标准测试条件下,电感温升不超过允许值的连续工作电流,高温环境需适当降额);
    • 饱和电流(I₍sat₎):500mA(电感值下降30%时的峰值电流,超过该值会导致储能能力骤降,引发电路电压波动);
  3. 直流电阻(DCR):1.117Ω。低DCR设计可减少电流功耗,例如370mA工作电流下,功耗约0.15W(P=I²×R),有助于控制设备温升;
  4. 类型:非屏蔽电感。相比屏蔽电感成本更低,但EMI抑制能力较弱,需结合电路EMI要求选型。

三、封装与物理特性

SM4532-680MT采用小型化SMD封装,具体尺寸为4.5mm(长)×4mm(宽),适配自动化贴装生产线,生产效率高。该封装符合主流PCB布局规范,可直接替换同尺寸同类电感,无需调整电路设计,完美契合智能手环、蓝牙耳机等紧凑设备的内部空间需求。

四、典型应用场景

结合参数与封装特性,SM4532-680MT适用于以下场景:

  1. 小型DC-DC转换器:如12V转5V、5V转3.3V的低功率降压电路,电感储能满足<370mA负载的能量需求;
  2. LED驱动电路:小功率LED背光(如智能手表屏幕)或指示灯驱动,电感滤波可稳定电流输出,避免闪烁;
  3. 便携式电子设备:智能手环、蓝牙耳机、运动相机等设备的电源模块,小尺寸封装契合设备轻薄化趋势;
  4. 物联网终端节点:低功耗传感器(如温湿度、运动传感器)的电源滤波与储能,非屏蔽设计降低节点成本;
  5. 消费类电子辅助电路:手机充电器辅助滤波、小型玩具电源电路等。

五、选型与使用注意事项

为确保电路稳定,选型时需注意:

  1. 电流匹配:连续工作电流≤370mA,峰值电流≤500mA(避免电感饱和);
  2. EMI考量:若电路对EMI敏感(如射频模块附近),需替换屏蔽电感或增加EMI滤波组件;
  3. 温度降额:环境温度超过25℃时,每升高10℃降额约10%(参考顺翔诺官方 datasheet);
  4. PCB布局:贴装时电感周围留散热空间,避免与电源芯片等发热元件过近;
  5. 精度适配:若需±10%以内精度(如精密滤波),需选择更高精度型号。

总结

SM4532-680MT是一款性价比突出的小电流功率电感,适合对空间和成本敏感的低功率电子设备,是便携式电子、物联网等领域的实用选型。

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
