FNR3010S4R7MT 产品概述
一、产品简介
FNR3010S4R7MT 是长江微电（cjiang）推出的一款表面贴装功率电感，封装尺寸为 3.0 × 3.0 mm（SMD）。该器件采用磁胶屏蔽结构，适用于对体积、效率和电流能力有要求的小型电源与滤波场合。额定电流与饱和电流参数匹配紧凑电源设计，可在有限空间内提供稳定的电感性能。
二、主要参数
- 电感值：4.7 μH，公差 ±20%
- 额定电流（Irms）：1.1 A
- 饱和电流（Isat，规定电感下降一定比例时）：1.05 A
- 直流电阻（DCR）：约 293 mΩ
- 类型：磁胶屏蔽电感（屏蔽型功率电感）
- 封装：SMD，3 × 3 mm
三、特性与优势
- 小尺寸：3×3 mm 封装，有利于高密度布板和便携设备空间优化。
- 屏蔽结构：磁胶屏蔽降低外泄磁场，减少对周边器件的干扰。
- 功率导向：1.1 A 的额定电流适合轻中功率点对点电源、降压转换等应用。
- 稳定性：适当的饱和电流保证在接近工作点时电感值衰减受控。
四、典型应用场景
- 手机、平板等移动终端的电源滤波与能量储存
- 小型降压（Buck）转换器输入/输出电感
- 模块化电源、通信设备、消费电子的 EMI 抑制与电源去耦
五、使用建议与注意事项
- 工作电流应尽量低于额定电流 1.1 A，避免长期接近或超过 Isat（1.05 A）以防电感值明显下降与发热。
- DCR 较高（≈293 mΩ），在设计时需考虑导通损耗与温升，必要时评估热阻与散热路径；布局时采用较短粗的电源走线、适当的铜箔/散热过孔。
- 开关器件附近布线应短而粗，输入与输出端应靠近电感器两端放置电容，减少回路面积以降低 EMI。
- 焊接工艺遵循无铅回流曲线，避免超温或长时间过热；贴装时注意元件方向与引脚焊盘匹配，避免机械应力。
- 在高频脉冲条件下注意电感的直流偏置特性，必要时参考详细曲线或样品测试确定实际有效电感。
六、封装与采购提示
产品编号：FNR3010S4R7MT，品牌：cjiang（长江微电），SMD 3×3mm 封装。批量采购前建议索取样品进行实际电路验证，并确认供应商的规格书与放电/温升曲线，以保证在目标工况下满足性能要求。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
