FNR4030S1R0MT 产品概述
一、主要参数与型号识别
FNR4030S1R0MT 为长江微电（cjiang）推出的一款功率型磁胶屏蔽片式电感，关键参数如下：电感值 1 μH，公差 ±20%；额定工作电流 4.7 A；饱和电流（Isat）5.7 A；直流电阻（DCR）约 18 mΩ；封装为 SMD，外形约 4 × 4 mm，适合高密度贴片设计。
二、器件特点与优势
- 磁胶屏蔽结构可抑制外泄磁场，降低对周边器件的磁耦合和干扰；
- 低 DCR（≈18 mΩ）有利于减小 I²R 损耗，提高转换效率和降低发热；
- 较高的额定与饱和电流（4.7 A / 5.7 A）适用于中高电流点负载；
- 4×4 mm 紧凑封装，便于在空间受限的电源模块或点载板上布局。
三、典型应用场景
- 同步降压/升压 DC–DC 转换器（点负载、通信/工业电源）；
- LED 驱动与电源滤波；
- 输入/输出的电磁干扰（EMI）滤波及功率环路储能；
- 电源管理模块（VRM、PMIC 周边元件）。
四、设计与选型建议
- 连续工作电流以额定 4.7 A 为准，瞬态脉冲可接近但不长期超过 Isat 5.7 A，以避免电感量显著下降并产生过热；
- 关注 DCR 对功耗与温升的影响，按 I²R 计算损耗并评估温升与散热；
- 工作频率提高时需评估铁损与磁芯材料特性，建议参考厂家提供的频响／损耗曲线；
- PCB 布局：尽量缩短电源回路长度、将输入/输出电容靠近电感放置、加大铜箔和过孔以改善散热并减小环路面积。
五、可靠性与装配注意
- 采用 SMD 贴装，建议按供应商推荐的回流焊工艺（参考厂方数据表）进行焊接；
- 装配时避免在受力位置施加过大机械应力；对长期可靠性、湿敏等级和温度循环性能建议索取厂方测试报告确认。

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.
