PSA MCS0420-100MN1 功率电感产品概述

一、产品基本信息

PSA MCS0420-100MN1是信昌电陶(PSA)推出的贴片式功率电感,专为低中功率直流变换、滤波电路设计。型号中:

  • “MCS0420”代表贴片功率电感系列;
  • “100”对应标称电感值10μH;
  • “MN”表示精度±20%;
  • 后缀“1”为规格代码。

该电感适配自动化贴片生产工艺,广泛应用于消费电子、车载电子、工业控制等领域的电源电路,是紧凑布局场景的高性价比选择。

二、核心电气参数详解

核心参数直接决定适用场景,需重点关注以下4项:

1. 电感值与精度

标称电感值10μH,精度±20%(实际范围8μH~12μH)。此精度满足大多数功率电路的滤波、储能需求——无需过高精度即可实现稳定的电压变换,同时降低成本。

2. 额定电流(Irms)

1.2A(有效值)。额定电流是指电感连续工作时,自身温升不超过行业常规标准(≤40℃) 的最大电流。选型时需优先匹配:若工作电流超过额定值,电感会因过热导致性能下降甚至损坏。

3. 饱和电流(Isat)

2.2A。饱和电流是磁芯磁化饱和、电感值下降至初始值30%时的电流(厂家标准)。该值远高于额定电流(1.83倍),意味着短时过载(如启动瞬间、脉冲电流) 下仍能保持基本电感特性,避免电路性能突变。

4. 直流电阻(DCR)

256mΩ(毫欧)。DCR是电感绕组的直流电阻,直接影响功耗:1.2A工作电流下,功耗约0.37W(P=I²×R),低DCR设计可减少电源损耗,提升电路效率。

三、封装与物理特性

该电感采用紧凑SMD封装,规格为4.0mm×4.6mm×2.0mm(长×宽×高),适配高密度电路板:

  • 尺寸兼容性:符合常规贴片焊盘标准,无需特殊PCB设计;
  • 重量:约0.2g(估算),轻量化适合便携设备;
  • 焊接工艺:支持回流焊、波峰焊(回流焊峰值温度260℃±5℃,持续时间≤10s),符合电子行业标准。

四、典型应用场景

基于小体积、中功率、高饱和电流的特点,主要应用于:

1. DC-DC转换器

降压(Buck)、升压(Boost)电路的储能电感,适配5V→3.3V、12V→5V等低中压变换(如手机充电模块、路由器电源)。

2. 电源滤波电路

抑制开关电源纹波噪声,提升输出电压稳定性(如LED驱动电源、工业电源滤波)。

3. 小功率LED驱动

1-3W LED串/并联驱动的电感滤波,支持台灯、小夜灯等便携照明设备。

4. 车载电子

车载USB充电、中控屏电源等低功率场景(需配合-40℃~85℃车载级温度范围)。

五、核心技术优势

  1. 小体积高密度:体积比传统插件电感缩小60%以上,适配便携设备紧凑布局;
  2. 高过载能力:饱和电流是额定电流的1.83倍,短时过载不影响电路性能;
  3. 低功耗设计:256mΩ低DCR,配合1.2A额定电流,可实现90%+电路效率;
  4. 品牌可靠性:信昌电陶产品通过RoHS、REACH认证,批量生产一致性好。

六、选型与使用注意事项

  1. 电流匹配:实际工作电流≤1.2A(有效值),脉冲峰值电流≤2.2A;
  2. 电感验证:高精度电路需实测电感值(±20%范围内),确保设计需求;
  3. 焊接控制:避免焊接温度过高(≥270℃),防止磁芯性能下降;
  4. 环境适配:常规工作温度-25℃~85℃,极端场景需确认厂家扩展规格;
  5. PCB布局:靠近电源芯片放置,缩短走线长度,降低电磁干扰(EMI)。

总结

PSA MCS0420-100MN1凭借小体积、高可靠性、适配多场景的特点,是消费电子、车载电子等领域电源电路的高性价比选择,可满足批量生产与紧凑设计需求。

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
