FPB252012D-1R0MT0 产品概述

一、产品简介

FPB252012D-1R0MT0 是长江微电(cjiang)推出的一款表面贴装一体成型磁胶屏蔽电感,尺寸为 2.5 × 2.0 × 1.2 mm。该器件以小封装、高电流能力和良好的磁屏蔽特性为设计目标,适用于移动终端、消费电子、电源管理模块及各类开关电源滤波场景。其标称电感值为 1 μH,公差 ±20%,在体积受限且需承受较大直流偏置电流的场合表现良好。

二、主要规格

  • 品牌:cjiang(长江微电)
  • 型号:FPB252012D-1R0MT0
  • 电感值:1 μH(±20%)
  • 额定电流(Irated):4.1 A
  • 饱和电流(Isat):5 A(厂家定义下的典型饱和点,电感下降到一定比例时测得)
  • 直流电阻(DCR):42 mΩ
  • 类型:磁胶屏蔽电感(磁性材料+屏蔽胶体结构)
  • 封装:SMD,一体成型,尺寸 2.5 × 2.0 × 1.2 mm

三、结构与封装

该器件采用一体成型工艺,外形尺寸小巧,适配高密度贴装。磁胶屏蔽结构通过磁性材料与屏蔽层的结合,抑制外泄磁场,减小对附近敏感电路的干扰,同时保留较高的电流能力和较低的直流电阻。SMD 封装便于自动化贴装和回流焊接,适用于批量生产。

四、性能特点

  • 小体积高电流:2.5×2.0×1.2 mm 的小封装内实现 4.1 A 的额定电流,满足便携设备与功率密度要求高的电源设计。
  • 良好饱和特性:5 A 的饱和电流保证在短时过载或大电流纹波条件下电感不易失效,适用于降压(buck)型 DC-DC 以及电源滤波。
  • 低 DCR:42 mΩ 的直流电阻在同体积器件中属于合理水平,有助于降低功耗与热量积累。
  • 磁胶屏蔽:有效降低磁辐射与相互干扰,便于与敏感模拟或射频电路共存。
  • 一体成型与 SMD:提高机械强度与可靠性,适配常规回流焊工艺。

五、典型应用

  • 移动设备电源管理(智能手机、平板等)
  • DC-DC 降压转换器的输出滤波或能量储存元件
  • LED 驱动、电源模块与电源杂散纹波抑制
  • 工业控制与便携仪器的电源滤波与 EMI 抑制
  • 各类要求高电流密度且空间受限的电子系统

六、选型建议与注意事项

  • 电流裕量:尽量让工作直流电流低于额定电流 Irated 的 80% 以保证长期可靠性和温升控制;若存在较大电流尖峰或纹波,应参照饱和电流 Isat 评估电感随电流变化的影响。
  • DCR 与效率:42 mΩ 的 DCR 会带来一定的功耗(P = I^2 × DCR),在高电流场景下需评估热量与系统效率。
  • 频率匹配:该类型电感适合开关频率较高的 DC-DC 应用,但在具体频率点的频率特性(如自谐频率、频率响应)需参考厂家详细测试曲线以确保滤波性能。
  • 温度与环境:在高温环境中电感值和 DCR 会发生变化,设计时应考虑温度漂移与可靠性要求。
  • 封装与布局:因为具备屏蔽特性,对布局要求相对宽松,但仍建议保持良好散热通道和合理走线以降低寄生影响。

七、可靠性与焊接建议

  • 焊接工艺:支持标准回流焊,推荐按厂方回流曲线控制峰值温度和保温时间以保障焊接可靠性。
  • 机械强度:一体成型结构增强了抗震动与抗冲击性能,但在波峰焊或手工焊接中应避免过长期高温暴露。
  • 可靠性测试:通过温度循环、湿热、振动及冲击测试可验证在极端环境下的长期性能,建议在关键应用中参考厂方可靠性报告或做定制验证。

八、包装与订购信息

FPB252012D-1R0MT0 常以卷带(Tape & Reel)形式供货,便于贴片机自动化装配。订购时请确认最小起订量、交期和是否满足 RoHS 等环保法规要求。对于特殊批次或需要更严格参数控制的应用,可与长江微电技术支持联系以获取完整数据手册和样品支持。

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.
