FNR4030S100MT 产品概述
一、概述
FNR4030S100MT 是长江微电（cjiang）推出的一款表面贴装功率电感，标称电感值为 10μH（±20%），专为开关电源滤波与能量储存设计。该器件采用磁胶屏蔽结构，封装尺寸为 4×4mm，兼顾小型化与磁场抑制，适用于空间受限的中低功率应用场景。
二、主要参数
- 电感值：10 μH，公差 ±20%
- 额定电流（Ir）：1.6 A（建议连续工作电流）
- 饱和电流（Isat）：2.4 A（电感值下降显著前的临界值）
- 直流电阻（DCR）：约 130 mΩ
- 类型：磁胶屏蔽电感（SMD）
- 封装：4×4 mm 表面贴装
三、特色与优势
- 小体积高集成：4×4mm 封装便于在紧凑的电源模块或板级电源中布局。
- 良好电流承载能力：1.6A 连续电流适合常见降压转换器与滤波器应用，2.4A 饱和电流提供短时冲击余量。
- 低漏磁设计：磁胶屏蔽结构能有效减小对周边敏感元件的磁干扰。
- 性能稳定：合适的 DCR 在效率与热耗之间取得平衡，便于系统热设计。
四、典型应用
- 同步/非同步降压（Buck）转换器滤波电感
- 电源输入/输出滤波、LC 滤波单元
- LED 驱动与车载电子（需按温度与可靠性校核）
- 电池供电设备与便携式电源管理模块
五、使用与布局建议
- 额定电流为连续允许值，建议在实际设计中按 70%~80% 规则降额以延长寿命并减少温升。
- 布线尽量缩短电感与开关管、输出电容之间的回流路径，降低寄生电感与 EMI。
- 对热敏感应用应评估 PCB 散热与元件间距，必要时采用铜厚或散热过孔辅助散热。
- 焊接工艺按常规 SMD 回流曲线执行，避免超过器件允许的最高回流温度（参考厂商焊接规范）。
六、选型与可靠性
在选型时综合考虑电感值容差、DCR 对效率的影响、以及饱和电流对瞬态性能的限制。对要求更高电流或更低 DCR 的场合，可优先选择额定电流和 Isat 更高的同系列或替代型号。建议在样机阶段进行温升、效率与 EMI 测试，确认在目标工况下满足系统要求。

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.
