顺络MPH252010C3R3MT功率电感产品概述

一、产品基本身份与系列定位

顺络MPH252010C3R3MT属于MPH系列功率电感,是针对小型化电子设备电源管理场景设计的表面贴装(SMD)电感。型号中“MPH”为顺络功率电感系列代号,“252010”对应公制封装尺寸(2.5×2.0×1.0mm),“C3R3”明确电感值为3.3μH,“MT”为封装类型标识。产品以“小封装承载大电流”为核心设计方向,适配便携设备、智能穿戴等空间受限的应用需求,是顺络在中低功率电源电感领域的典型产品之一。

二、核心电气参数与性能意义

该电感的关键参数围绕“电源储能/滤波”核心功能设计,各项参数的实用价值如下:

  1. 电感值:3.3μH ±20%:标准电感量满足DC-DC转换、EMI滤波等基础电源需求,±20%的精度覆盖批量生产的一致性要求,无需额外匹配调试;
  2. 额定电流:1A:正常工作状态下允许的最大直流电流,在此电流下电感量、DCR等参数无明显漂移,可稳定支撑小功率电源模块;
  3. 饱和电流(Isat):1A:磁芯开始饱和时的临界电流(电感量下降至初始值的30%以内),此值与额定电流一致,说明产品在额定电流下无磁饱和风险,余量设计合理;
  4. 直流电阻(DCR):250mΩ:绕组的直流损耗电阻,1A电流下功耗仅0.25W(I²R),发热低,可降低设备整体热管理压力。

三、封装与物理特性解析

产品采用SMD 1008英制封装(对应公制2520),物理特性适配自动化贴装与小型化设计:

  • 尺寸:2.5×2.0×1.0mm:超薄超小体积,可轻松集成于智能手机、智能手环等便携设备的高密度PCB上;
  • 工作温度范围:-40℃~+125℃:宽温特性满足工业级环境(如车载小设备、户外便携终端)的温度波动需求;
  • 焊接与存储:支持无铅回流焊(峰值温度≤260℃),存储环境建议温度-5℃~+40℃、湿度≤60%,避免磁芯受潮影响性能;
  • 引脚材质:采用镀锡引脚,焊接可靠性高,抗腐蚀性能优异。

四、典型应用场景

基于参数特性,该电感主要应用于以下场景:

  1. 便携电子设备:智能手机、平板电脑的DC-DC降压模块(如CPU供电、屏幕背光电源);
  2. 智能穿戴:智能手环、手表的充电电路与电池管理系统(BMS)滤波;
  3. 小型家电:智能音箱、无线耳机充电盒的电源转换电路;
  4. 工业控制:小型PLC、传感器模块的电源滤波与储能;
  5. 通信设备:微型路由器、蓝牙模块的电源稳压电路。

五、产品优势与市场价值

对比同类中低端功率电感,MPH252010C3R3MT具备以下优势:

  • 小封装大电流:1008封装下实现1A额定电流,比同尺寸竞品电流密度提升约15%;
  • 低损耗高可靠性:250mΩ低DCR降低功耗,顺络自主磁芯材料(铁氧体基)抗老化性能优异,寿命可达5万小时以上;
  • 宽温适配性:-40℃~+125℃覆盖工业级与消费级双重场景,无需分场景选型;
  • 一致性稳定:批量生产参数离散度≤10%(远低于±20%精度要求),适合大规模自动化生产。

六、选型与使用注意事项

为确保产品性能稳定,需注意以下要点:

  1. 电流限制:实际工作电流需≤1A(额定电流),避免超过饱和电流导致电感量下降;
  2. 散热设计:若持续工作在1A电流下,建议在PCB对应位置铺铜散热,降低热阻;
  3. 焊接规范:遵循IPC-7525回流焊标准,避免峰值温度过高损坏磁芯;
  4. 存储与运输:开封后建议1个月内使用,运输过程避免剧烈振动(防止引脚变形)。

该产品凭借紧凑尺寸、稳定性能与宽场景适配性,成为消费电子、工业控制领域小功率电源电路的优选电感之一。

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
