FNR5040S150MT 产品概述
一、产品简介
FNR5040S150MT 是长江微电（cjiang）推出的一款磁胶屏蔽型功率电感，额定电感值 15 μH（±20%），专为中低功率开关电源与滤波电路设计。器件采用 SMD 贴片封装（5×5 mm），针对空间受限、要求抗干扰和高可靠性的应用场景优化制造。
二、主要电气参数
- 电感值：15 μH，公差 ±20%（设计时请考虑容差带来的电路偏差）
- 额定电流（Ir）：2.05 A（连续工作参考值）
- 饱和电流（Isat）：2.2 A（接近该电流时电感量将显著下降）
- 直流电阻（DCR）：112 mΩ（影响能量损耗与温升）
- 类型：磁胶屏蔽电感，抑制外泄磁场，降低对周边器件的干扰
注：在 2.05 A 时器件的 I^2R 损耗约为 0.47 W，设计时需考虑热管理与降额使用。
三、结构与封装
FNR5040S150MT 采用磁胶屏蔽结构，既保证较高的磁通利用率，又抑制外部磁场泄露，适合密集 PCB 布局。SMD 5×5 mm 标准外形便于自动贴装与回流焊工艺，推荐按厂家出厂回流曲线进行焊接（常见无铅回流峰值 ≤ 260°C）。
四、典型应用
- 同步整流升降压（buck/boost）开关电源的储能电感
- 输入/输出滤波器（DC-DC 模块、分立电源）
- 工业控制、通信设备、电池管理系统（BMS）等要求中等电流且体积受限的场合
五、选型与使用建议
- 电流降额：建议在连续工作中保留一定余量（典型取 70%~90% 的额定电流），以降低温升与保持稳定电感。
- 饱和裕量：若电路可能出现短时电流冲击，应保证最大瞬时电流低于 Isat，避免电感量突降影响环路稳定。
- DCR 与效率：112 mΩ 的 DCR 在高电流下会带来显著损耗，应在热仿真或实测中确认温升并考虑并联或更低 DCR 型号。
- PCB 布局：电感两端走线尽量短且宽，靠近功率 MOSFET/电容，使用充足的铜皮散热并保持良好接地。
六、可靠性与测试
出厂通常经过电感值、DCR、耐温循环和焊接可靠性测试。建议在应用开发阶段进行温升测试、长期老化和电流冲击测试，以验证在目标工况下的可靠性。
七、包装与订购信息
品牌：cjiang（长江微电）；封装：SMD 5×5 mm。订购时请确认包装形式（盘带/卷带）和批次，以便生产兼容。如需替代或并联方案，可联系供应商获取更低 DCR 或更高电流等级的型号。

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.
