FNR6045S120MT 产品概述
一、产品简介
FNR6045S120MT 是长江微电（cjiang）推出的一款功率型磁胶屏蔽贴片电感，封装为 SMD，外形尺寸约 6×6 mm，额定工作电流 2.4A，饱和电流（Isat）3A，电感量 12 µH（公差 ±20%），直流电阻（DCR）约 75 mΩ。该器件针对中小功率 DC-DC 转换器与电源滤波场景设计，兼顾体积、磁屏蔽与热性能。
二、主要技术参数
- 品牌：cjiang（长江微电）
- 型号：FNR6045S120MT
- 电感值：12 µH ±20%
- 额定电流：2.4 A（温升与长期工作限制）
- 饱和电流（Isat）：3 A（磁芯开始强烈下降点）
- 直流电阻（DCR）：≈75 mΩ
- 类型：磁胶屏蔽电感（屏蔽结构，降低外泄磁场）
- 封装：SMD，尺寸 6×6 mm
三、特点与优势
- 高电流承载能力：2.4A 的额定电流适合小型功率稳压与后级滤波应用，Isat 3A 提供短时过载余量。
- 屏蔽结构：磁胶屏蔽设计减少对周围元件的磁干扰，有利于高密度布局。
- 低 DCR：75 mΩ 的直流电阻在同等级产品中对效率影响较小，有利于降低功耗和发热。
- SMD 贴片化：利于自动化装配和批量生产，适应紧凑 PCB 布局。
四、典型应用场景
- 同步降压/升压 DC-DC 转换器的输出或输入滤波器
- 开关电源（SMPS）后级滤波与能量储存
- 电池供电设备、便携式设备电源管理
- 工业控制与车载电子（低电压小功率子系统）等
五、使用与选型建议
- 留有裕量：建议在实际设计中对额定电流采用一定的降额（例如 70–80%）以保证长期可靠性并降低温升。
- 考虑 DCR 与效率：75 mΩ 会在大电流下造成一定的 I²R 损耗，评估发热与散热条件，必要时选择更低 DCR 或更大封装。
- 饱和裕度：若电路可能出现短时大电流冲击，应确保 Isat 能满足磁通密度要求，避免电感突降影响稳定性。
- 替代选型：替代品需匹配电感量、电流等级、DCR 以及封装体积与屏蔽特性，优先选择同类磁芯材料与结构的产品。
六、封装、焊接与可靠性建议
- 焊接工艺：建议采用行业常规无铅回流工艺（参考峰值约 245°C 的曲线），避免过高温度和过长保温时间。
- PCB 布局：电感应尽量靠近电源开关器件与输入/输出电容，走线短粗，提供良好散热通道；必要时增加过孔增强散热。
- 测试与验证：建议在目标工作频率和温度下测量电感量、DCR 及温升；在样机上进行高温、高湿和振动等可靠性验证。
FNR6045S120MT 适合对体积、屏蔽和中等电流承载有综合需求的电源设计场景，是常见的功率滤波与能量储存元件选择。若需进一步的电气特性曲线或样品数据表，请联系供应商获取完整规格书与器件样本。

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.
