SMMS0420-100M功率电感产品概述

一、产品定位与核心价值

SMMS0420-100M是顺翔诺(SXN)推出的小体积贴片式功率电感,针对高密度、中等功率电子电路设计,核心价值在于在紧凑封装下实现「高电流承载+低损耗」的平衡,适配消费电子、物联网终端等对尺寸敏感的场景。产品聚焦三大核心特性:小封装(4.6×4.2mm)、高饱和电流(2A)、低直流电阻(258mΩ),解决传统功率电感在便携设备中「体积大、电流不足、发热明显」的痛点。

二、关键参数深度解析

SMMS0420-100M的参数直接决定应用适配性,需重点关注以下维度:

1. 电感量与精度

标称电感值为10μH,精度±20%(实际范围8μH12μH)。该精度满足DC-DC转换器、LED驱动等电路的常规需求(此类电路对电感精度要求多在±10%±30%),无需额外校准即可稳定工作。

2. 电流承载能力

  • 额定电流(Irms):1.6A
    指连续工作时允许通过的最大有效值电流,此时电感温升≤40℃(行业标准),长期工作无性能衰减,适配中等功率负载(如手机CPU供电)。
  • 饱和电流(Isat):2A
    磁芯饱和时的峰值电流(电感值下降30%为阈值),可应对电路瞬态波动(如电源启动、负载突变),避免电感饱和导致输出电压跌落、纹波增大。

3. 直流电阻(DCR)

标称258mΩ,属于同类小封装电感的低损耗水平。DCR直接影响铜损(P=I²×DCR),在1.6A额定电流下损耗仅约0.6W,可有效降低发热、提高电源转换效率。

三、封装与物理特性

SMMS0420-100M采用SMD表面贴装封装,尺寸为4.6mm×4.2mm(长×宽),具有以下优势:

  • 高密度布局适配:可与0402、0603等小型元件协同,缩小PCB面积,适合智能手机、智能手表主板;
  • 自动化生产兼容:符合SMT标准,支持高速贴装与回流焊(峰值温度≤260℃,适配主流设备);
  • 结构稳定性:磁芯+线圈一体化设计,抗振动(10~2000Hz,加速度≤1.5g)、抗冲击,适应移动设备日常使用。

四、典型应用场景

结合参数特性,产品主要适用于以下场景:

1. 便携电子电源管理

  • 智能手机/平板:主板DC-DC降压模块(5V转3.3V/1.8V),承载CPU、内存供电;
  • 智能穿戴:智能手表/手环电池供电电路,适配低功耗芯片中等电流需求。

2. 物联网终端

  • 传感器节点:温湿度、运动传感器电源,应对数据传输时的电流波动;
  • 小型网关:低功率WiFi/蓝牙模块供电,平衡体积与电流承载。

3. LED驱动电路

  • 小功率LED照明:手机闪光灯、智能台灯驱动电感,支持1A~2A峰值电流。

五、性能优势与差异化

相比同类竞品,SMMS0420-100M的核心优势:

  1. 电流密度高:同体积下饱和电流是竞品的1.2~1.5倍;
  2. 损耗控制佳:1.6A额定电流下损耗比竞品低10%~15%;
  3. 成本性价比:顺翔诺量产优势使成本低于进口产品,适合大规模消费电子应用。

六、可靠性与环境适应性

产品经过严格可靠性测试,满足:

  • 工作温度:-40℃~+85℃,适应工业级(户外传感器)与消费电子(高温手机)场景;
  • 长期稳定性:1000小时额定电流工作,电感量漂移≤5%,DCR变化≤3%;
  • 耐湿性能:符合JESD22-A101标准(85%湿度/85℃,1000小时),无性能衰减。

总结:SMMS0420-100M是专为中等功率、小体积场景设计的高性价比电感,在电流承载、损耗控制与封装尺寸上实现平衡,可广泛应用于消费电子、物联网领域,为电路提供可靠储能与滤波支撑。

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
