FNR5020S100MT 产品概述
一、产品简介
FNR5020S100MT 为长江微电（cjiang）推出的磁胶屏蔽功率电感，标称电感值 10 µH，公差 ±20%。器件为 SMD 封装（5×5 mm），适合用于功率变换与滤波场合，强调高密度、电流能力与良好屏蔽性能。
二、主要参数
- 电感值：10 µH（±20%）
- 额定电流（Ir）：1.7 A（连续）
- 饱和电流（Isat）：1.8 A
- 直流电阻（DCR）：143 mΩ
- 类型：磁胶屏蔽电感（磁性封装以抑制外泄磁场）
- 封装：SMD，5×5 mm
三、结构与封装特点
磁胶屏蔽结构在保持较高电感密度的同时，抑制外泄磁场，利于对周边敏感电路的干扰控制。5×5 mm 的标准贴片外形便于自动贴片与回流焊工艺，适合集成度较高的电源模块。
四、性能要点
- 大电流能力：额定 1.7 A，适合中小功率 DC-DC 降压、升压与输出滤波。
- 饱和裕量有限：Isat 仅为 1.8 A，离额定值接近，需注意瞬态与峰值电流可能导致 L 值下降。
- 损耗估算：在额定电流下铜损约 I^2·DCR ≈ 1.7^2×0.143 ≈ 0.41 W，设计时需考虑散热与效率影响。
- 公差较宽：±20% 适合对电感精度要求不高的电源滤波应用。
五、典型应用
- 降压/升压 DC-DC 电源的电感元件
- 输入/输出滤波与能量储存
- 电池供电设备、便携式设备的电源管理
- LED 驱动与通信设备电源模块
六、选型与使用建议
- 连续工况建议按额定电流的 70%–80% 进行选型，以避免磁饱和和过热。
- 对瞬态峰值电流（如启动或负载突变）需评估 L 对电路影响，必要时采用更高 Isat 的型号。
- 由于 DCR 相对偏高，若对效率要求严格，应评估整体损耗并考虑并联或替代型号。
- 在 PCB 布局上尽量缩短电感与开关器件、输出电容之间的走线，增加焊盘铜厚以利散热。
七、可靠性与测试
建议在设计验证阶段查看厂方 L‑I、L‑f 曲线与温升数据，并进行温度循环、焊接可靠性与过流测试。批量使用前可要求样品做电感值、DCR 与饱和特性一致性验证。
八、采购与资料
器件型号：FNR5020S100MT，品牌：cjiang（长江微电），封装：SMD 5×5 mm。最终设计与可靠性评估应参考厂家完整规格书与 S-参数图表，必要时联系供应商获取样片与应用说明。

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.
