FWP252012P-1R0ML 产品概述

一、概述

FWP252012P-1R0ML 是长江微电(cjiang)推出的一款小尺寸、高电流承载能力的磁胶屏蔽功率电感。标称电感量为 1 μH,容差 ±20%,额定电流 3.5 A,饱和电流(Isat)4.4 A,直流电阻(DCR)约 41 mΩ,封装为 1008(片式封装)。该型号专为开关电源、点负载转换与电流滤波等功率线圈应用设计,兼顾体积、损耗与抗磁干扰能力。

二、主要性能特点

  • 大电流能力:静态额定电流 3.5 A,可在短时高负载或启动冲击下保持稳定工作;饱和电流 4.4 A,保证在接近饱和区仍有可用电感量。
  • 低直流电阻:DCR 约 41 mΩ,降低了铜损,有助于提升效率和减小温升。
  • 屏蔽结构:磁胶屏蔽设计有效抑制磁场外泄,减小对周围敏感器件的干扰,便于高密度布局。
  • 紧凑封装:1008 尺寸对空间受限的移动设备或主板点位非常友好,适合高密度 PCB 设计。

三、典型应用场景

  • DC-DC 降压/升压转换器(尤其是同步整流或大电流点负载)
  • 电源输出滤波与入/出滤波网络
  • LED 驱动电源、便携式电源管理模块
  • 通信设备、工业控制与电机驱动前级滤波
  • 需要低 EMI 并要求较高电流承载的小型化电源模块

四、布局与使用建议

  • 版图设计中尽量缩短电感与功率开关器件之间的回流路径,减小环路面积以降低 EMI 与损耗。
  • 电感焊盘与过孔应保证良好散热,必要时在焊盘下方或周围增加铜箔与过孔以改善热扩散。
  • 在靠近敏感模拟电路或高频信号线时,利用其屏蔽特性并留出一定间距,避免耦合干扰。
  • 焊接工艺采用推荐回流温度曲线,避免过高的峰值温度与长时间热暴露影响磁性材料特性。

五、可靠性与测试要点

  • 在样机验证阶段需关注在额定电流及接近 Isat 条件下的电感衰减曲线与温升曲线,确认满足系统稳定性要求。
  • 测试直流电阻变化、交流阻抗(频率响应)及磁饱和特性,评估在不同工作点的性能。
  • 评估在热循环、振动与湿热环境下的机械与电性能稳定性;必要时参考厂商完整数据手册与可靠性报告。

六、采购与封装信息

  • 品牌:cjiang(长江微电)
  • 型号:FWP252012P-1R0ML
  • 封装:1008 片式(便于自动贴装与回流焊接)
  • 主要参数汇总:L = 1 μH(±20%);Irated = 3.5 A;Isat = 4.4 A;DCR ≈ 41 mΩ;类型:磁胶屏蔽电感。

总结:FWP252012P-1R0ML 在体积受限但需承载较大电流与抑制电磁干扰的电源设计中具有良好性价比。设计时结合实际工作电流、饱和裕量与散热条件进行验证,可用于多种开关电源和滤波场景。如需具体温度范围、机械尺寸图或回流曲线等详细资料,建议参照长江微电的产品数据手册或联系供应商获取样片和评估报告。

Sourcing availability signal

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
