SMMS0420-1R0M功率电感产品概述

一、产品定位与品牌背景

SMMS0420-1R0M是顺翔诺(SXN)推出的贴片式功率电感,针对中小功率开关电源、便携式电子设备等场景设计,主打「小体积、高电流承载、低损耗」三大核心特性,为电路设计提供高效可靠的电感解决方案。顺翔诺作为专注电感研发与生产的品牌,其产品覆盖消费电子、工业控制等领域,SMMS0420系列是针对紧凑空间需求优化的核心产品线之一。

二、核心电气参数深度解析

该电感的关键参数明确了性能边界,每项指标均针对实际应用场景优化:

  1. 电感值与精度:标称1μH,精度±20%(范围0.8μH1.2μH),适配100kHz2MHz开关频率,满足多数DC-DC转换器的电感匹配需求;
  2. 额定电流(Irms):6A,指25℃环境下长期稳定工作的最大均方根电流,此时电感温升控制在安全范围(≤40K),避免热衰减;
  3. 饱和电流(Isat):7A,定义为磁芯饱和(电感量降至标称70%)时的电流,比额定电流高1A,为电路提供瞬态过流余量;
  4. 直流电阻(DCR):27mΩ(典型值),低电阻直接降低铜损——6A电流下损耗仅≈0.97W,显著提升电源效率。

三、物理特性与封装优势

采用SMD表面贴装封装,尺寸4.6mm×4.2mm(长×宽),具备三大封装优势:

  1. 高密度适配:小体积可节省30%以上PCB空间,适合智能手表、蓝牙耳机等便携设备的紧凑布局;
  2. 自动化兼容:支持高速贴装与回流焊工艺,焊接不良率≤0.1%,提升生产效率;
  3. 机械可靠性:一体化磁芯结构抗振动(10G/20~2000Hz)、抗冲击(100G/1ms),适应运输与使用中的机械应力。

四、性能特点与核心优势

通过材料优化与结构设计,实现多项性能突破:

  1. 低损耗高效能:低DCR+优化磁芯材料,6A电流下效率≥95%,减少电源发热;
  2. 宽温稳定工作:工作温度-40℃~125℃,适应北方户外低温、充电时内部高温等场景;
  3. 电流冗余设计:饱和电流比额定电流高16.7%,避免瞬态过流导致电感失效;
  4. 电感稳定性强:额定电流范围内电感量波动≤5%,保证DC-DC输出电压稳定,减少纹波干扰。

五、典型应用场景

SMMS0420-1R0M的参数特性适配多领域中小功率电源:

  1. 消费电子电源:手机快充充电器、移动电源的升压/降压模块(6A输出需求);
  2. 便携式智能设备:智能手表、TWS蓝牙耳机的电源管理电路(小体积需求);
  3. 小型工业模块:微型PLC、传感器节点的电源部分(宽温+抗振动需求);
  4. 车载小功率设备:车载USB充电器、胎压监测模块的电源电路(宽温适配车载环境)。

六、总结

SMMS0420-1R0M是一款高性价比的贴片功率电感,以「小体积、高电流、低损耗」为核心优势,覆盖消费电子、工业、车载等多场景的中小功率电源需求。其稳定的性能与合理的参数设计,为电子工程师提供了可靠的选型方案,适合追求效率与空间优化的电路设计。

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
