SM4532-4R7MT 功率电感产品概述

一、产品基本信息

SM4532-4R7MT是顺翔诺(SXN)品牌推出的非屏蔽贴片功率电感,采用SMD(表面贴装)封装,封装尺寸为4.5×4mm(对应行业公制规格,适配自动化贴片生产流程)。该电感专为中小功率电路的储能、滤波及DC-DC转换场景设计,兼顾体积紧凑性与性能稳定性,是消费电子、小型家电等领域的实用选型。

二、核心性能参数解析

该电感的关键指标明确,覆盖多数中小功率电路的需求,具体参数及意义如下:

  1. 电感值与精度:标称电感值为4.7μH,精度±20%——满足对电感值稳定性要求不苛刻但需持续储能的电路(如普通电源滤波);
  2. 电流特性:
    • 额定电流(Irms):1.15A——指电感可长期稳定工作的最大有效电流,超过此值会导致线圈发热超出安全范围;
    • 饱和电流(Isat):2A——指电感电感值下降至标称值30%(行业通用定义)时的电流阈值,若电路峰值电流接近2A,需注意性能波动;
  3. 直流电阻(DCR):108.7mΩ——线圈的直流损耗电阻,低DCR可减少功率损耗、降低发热,提升电路效率;
  4. 封装规格:4.5×4mm(长×宽),适配多数PCB板的常规布局,无需额外占用过多空间。

三、产品设计特点

  1. 非屏蔽结构优势:采用无屏蔽外壳设计,相比屏蔽电感体积更小、成本更低,适合对电磁干扰(EMI)要求不高的场景(如普通电源电路);
  2. 贴片适配性:SMD封装支持自动化贴装,符合现代电子制造的高效生产需求,无需手工焊接辅助;
  3. 低损耗设计:108.7mΩ的低DCR减少了电流通过时的热损耗,可长期连续工作而无需额外散热措施;
  4. 电流裕量充足:饱和电流(2A)高于额定电流(1.15A),可应对电路中的瞬时峰值电流(如开机浪涌),降低性能下降风险。

四、典型应用场景

SM4532-4R7MT因体积小、电流适配性强,适用于以下场景:

  1. 消费电子电源:手机充电器、移动电源的DC-DC升压/降压电路中的储能电感;
  2. 小型家电控制板:智能插座、小型加湿器、台灯的电源滤波与稳压模块;
  3. LED驱动电路:小功率LED灯串(如橱柜灯、小夜灯)的恒流驱动电感;
  4. 物联网低功耗设备:传感器节点、蓝牙模块等的电源管理电路(需低损耗、小体积)。

五、选型与使用注意事项

  1. 电流匹配:电路工作电流需控制在1.15A以内,峰值电流避免超过2A,否则可能导致电感值下降,影响电路稳定性;
  2. EMI敏感场景:若应用于射频电路、高精度仪器等对EMI要求高的场景,需搭配屏蔽罩或更换屏蔽电感;
  3. PCB布局建议:将电感放置在靠近电源输出端,减少线路损耗;同时避免密集布局,预留少量散热空间(虽DCR低,但长期工作仍需通风);
  4. 精度需求:±20%的精度适合储能滤波,若用于谐振电路、高精度滤波等场景,需更换±10%或更高精度的电感型号。

总结

SM4532-4R7MT作为一款高性价比的非屏蔽贴片功率电感,凭借紧凑尺寸、合理的电流裕量与低损耗设计,可满足多数中小功率电子设备的电源管理需求,是消费电子、小型家电等领域的可靠选型。

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
