FWP201610P-R47ML 产品概述
一、产品简介
FWP201610P-R47ML 为长江微电（cjiang）出品的一款磁胶屏蔽功率电感，尺寸属 0806 封装（2.0 × 1.6 mm，SMD-2P）。额定电感值 470 nH，公差 ±20%，设计用于贴片电源滤波与点对点电源管理场合，兼顾大电流通断能力与较低的直流电阻，适配现代高密度开关电源板级应用。
二、主要技术参数
- 电感值：470 nH（±20%）
- 额定电流（Ir）：3.5 A（连续允许工作电流）
- 饱和电流（Isat）：4.4 A（在该电流下电感值显著下降）
- 直流电阻（DCR）：33 mΩ
- 类型：磁胶屏蔽电感（屏蔽结构，降低漏磁）
- 封装：SMD-2P，2 × 1.6 mm（0806）
三、特点与优势
- 小尺寸、高电流：0806 小型封装同时支持数安培电流，适合空间受限的点对点供电设计。
- 低 DCR：33 mΩ 的直流电阻在功率环路中有助于降低 I^2R 损耗，提高转换效率。
- 良好饱和特性：Isat 达 4.4 A，能在瞬态或峰值电流条件下维持相对稳定的电感特性。
- 屏蔽结构：磁胶屏蔽减少对周围敏感器件的磁干扰，便于高密度布板。
四、典型应用场景
- 同步降压（buck）转换器的输出侧电感或输入滤波电感。
- 手机、平板、蓝牙设备及便携式电源模块的点对点供电。
- USB PD、充电管理、电源噪声抑制与电源滤波场合。
- 通信与消费电子中需要小型化与高电流能力的电源模块。
五、PCB 布局与使用建议
- 将电感尽量靠近开关器件或负载放置，缩短高频环路长度以减小寄生电感与EMI。
- 按厂家推荐脚位开铜，并采用较宽的铜箔和适当过孔来增强散热（多层板时建议接地平面下方铺铜）。
- 对于散热和电流承载，建议根据板厚（铜厚）与过孔数量评估热阻，必要时增加散热铜面积。
- 焊接工艺按照常规焊接曲线（参考 JEDEC）进行回流，避免超过所能承受的温度/时间极限。
六、可靠性与注意事项
- 电感值会随着直流偏置电流增加而下降，设计时应考虑 DC bias 特性对滤波/储能能力的影响。
- 额定电流 3.5 A 是在温升与性能允许范围内的连续工作值；峰值或短时脉冲可能超过但需注意饱和与温升。
- 可通过 I^2·DCR 估算直流损耗，例如在 3.5 A 下近似为 0.4 W 左右，用于评估温升与散热需求。
- 封装小且电流较大，长期高温或超载会影响寿命，应遵循应用环境的温度与振动规范。
如需进一步的电感随频率/电流的特性曲线、回流曲线或封装3D/PCB封装库（footprint），建议向供应商或长江微电索取详细数据手册与测试报告以便优化设计与可靠性验证。

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.
