FWP252010P-2R2ML 产品概述

一、产品简介

FWP252010P-2R2ML 是长江微电(cjiang)推出的一款小尺寸磁胶屏蔽功率电感,标称电感值 2.2 µH,公差 ±20%。该器件为表面贴装(SMD-2P)封装,外形尺寸约 2.5 × 2.0 mm,针对空间受限且要求较高电流能力的开关电源和功率管理应用进行优化设计。

二、主要电气参数

  • 标称电感:2.2 µH ±20%
  • 额定电流(Irated):2.3 A(热稳定工作电流)
  • 饱和电流(Isat):2.4 A(L降至初始值一定比例时的电流)
  • 直流电阻(DCR):≈99 mΩ(典型)
  • 类型:磁胶屏蔽电感(屏蔽结构,有利于降低磁耦合与 EMI)
  • 封装:SMD-2P,尺寸约 2.5 × 2.0 mm

三、结构与封装特点

FWP252010P-2R2ML 采用磁胶屏蔽结构,既能保证较好的磁通闭合以降低辐射干扰,又通过磁芯与绕组的工艺配合在小体积内实现较高的电流承载能力。SMD-2P 小型贴片封装便于自动化贴装与回流焊工艺集成,适合高密度 PCB 设计。

四、主要特性与优势

  • 小尺寸:2.5 × 2.0 mm 的封装适合手机、可穿戴设备、物联网终端等空间受限应用。
  • 高电流能力:额定电流 2.3 A,饱和电流 2.4 A,可满足中等功率降压转换器的电感需求。
  • 屏蔽设计:磁胶屏蔽结构有效抑制磁辐射,利于满足系统 EMI 要求。
  • 低 DCR:约 99 mΩ 的直流电阻有助于降低导通损耗,提高转换效率。
  • 兼容 SMT 生产:适合自动贴片与回流焊流程,良好的可靠性与批量生产一致性。

五、典型应用场景

  • 开关稳压器(Buck)输出电感或输入滤波
  • 手机、平板、穿戴式等便携终端的电源管理
  • 蓝牙/LoRa/IoT 模块供电滤波与去耦
  • LED 驱动与小功率 DC-DC 转换模块
  • 工业或汽车电子的本地去耦(需按环境温度与认证要求确认)

六、选型与使用建议

  • 饱和裕度:Isat(2.4 A)与额定电流(2.3 A)接近,建议在实际设计中对电感电流做 10–30% 的降额处理,避免靠近饱和区工作,特别是在脉冲电流或温升较高的情况下。
  • 温升与散热:长期高电流运行时请关注 PCB 散热路径和周围器件热源,必要时评估在实际工况下的温升对 DCR 与电感值的影响。
  • 滤波特性:由于公差 ±20%,对要求严格的滤波或谐振点敏感的电路需进行电路容差分析或使用配对元件。
  • 尺寸匹配:封装为 2.5×2.0 mm,布板时留足锡垫与焊盘尺寸以保证可靠焊接与热循环能力。

七、焊接与可靠性注意事项

  • 采用常规 SMT 回流焊工艺,遵循无铅回流曲线或供应商推荐的回流温度剖面。
  • 避免在器件上施加过大的机械应力(如弯曲、强力擦拭),以免损伤磁芯或引脚。
  • 对于要求高可靠性的应用(汽车、医疗等),建议向厂家索取完整可靠性与环境试验报告(如温度循环、湿热、机械振动等)。

八、采购与技术支持

型号:FWP252010P-2R2ML

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
