FWP252012P-R47ML 产品概述
一、概述
FWP252012P-R47ML 是长江微电（cjiang）推出的一款磁胶屏蔽功率电感，额定电感值为 470 nH（±20%），面向高密度开关电源与功率管理场景。器件采用 1008（2.5 × 2.0 mm）SMD-2P 小封装，体积小、饱和电流高、直流损耗低，适合集成度要求较高的板级电源设计。
二、主要电气参数
- 电感值：470 nH，公差 ±20%
- 额定电流（Irated）：4.6 A（连续工作条件下参考值）
- 饱和电流（Isat）：5.3 A（磁通密度接近饱和时指定）
- 直流电阻（DCR）：约 21 mΩ
- 类型：磁胶屏蔽电感（屏蔽型，降低外泄磁场）
- 封装：SMD-2P，1008（2.5 × 2.0 mm）
三、特性与优势
- 体积小、饱和电流高：在 2.5×2.0 mm 小封装下仍能提供 4.6 A 额定电流和 5.3 A 饱和电流，适合空间受限但电流要求高的场合。
- 低 DCR：约 21 mΩ 的直流电阻有助于降低导通损耗与发热，提高转换效率。
- 屏蔽结构：磁胶屏蔽设计有效抑制磁场外泄，便于与其它敏感器件近距离布局，减少 EMI 干扰。
- 工艺稳定：适合回流焊工艺的 SMD 封装，便于自动贴装与大批量生产。
四、典型应用
- 降压（Buck）开关电源输出滤波与能量储存
- 同步整流电源与电压稳压模块（VRM）
- LED 驱动电源、车载电源模块、通信与工业电源
- USB-PD、移动电源、消费电子电源管理场景
五、选型与注意事项
- 电流裕量：建议在额定电流以下工作（常规设计可留 10%~30% 余量），并结合目标环境温度与散热条件评估温升。
- 饱和裕度：若电感需承受瞬态大电流，关注 Isat 指标，保证工作点不会引起电感饱和导致电流突变。
- PCB 布局：将电感靠近开关器件与输出电容放置，尽量缩小电流回路面积；屏蔽型便于与敏感信号线并行走线。
- 温度与可靠性：器件长期工作温度范围与热阻、老化特性请以厂商规格书为准，必要时做热仿真与实际温升测量。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
