FNR6028S101MT 产品概述
一、产品简介
FNR6028S101MT 为 cjiang（长江微电）推出的一款功率电感，属于磁胶屏蔽型表面贴装（SMD）器件。器件尺寸紧凑，典型封装 6×6 mm，适合在空间受限的电源应用中提供稳定的储能与滤波功能。标称电感值为 100 μH，公差 ±20%，面向中低功率开关电源与 EMI 滤波场合。
二、主要参数
- 电感值：100 μH（±20%）
- 额定电流（Irated）：770 mA
- 饱和电流（Isat）：710 mA（在此电流下电感下降到一定比例）
- 直流电阻（DCR）：650 mΩ
- 类型：磁胶屏蔽电感（屏蔽型，减小磁泄漏）
- 封装：SMD，6×6 mm
- 品牌：cjiang（长江微电）
三、产品特性与优势
- 屏蔽结构：磁胶屏蔽设计降低磁通外泄，便于靠近敏感电路布局，减少互扰。
- 紧凑尺寸：6×6 mm SMD 形式易于自动贴装，适合高密度 PCB 布局。
- 中等电流能力：770 mA 额定电流适合中小功率 DC-DC 降压、升压模块及 LED 驱动应用。
- 可预测功耗：较高的 DCR 带来可控的铜损，便于热设计与可靠性评估。
四、典型电气损耗估算
- 在额定电流 0.77 A 下，铜损 P = I^2·DCR ≈ 0.77^2 × 0.65 Ω ≈ 0.39 W；
- 在接近饱和电流 0.71 A 下，P ≈ 0.71^2 × 0.65 Ω ≈ 0.33 W。
建议电路设计中考虑散热与电感电流的余量，避免长时间工作在接近饱和区。
五、典型应用
- 开关电源（DC-DC 降压/升压）储能与滤波
- 输入／输出滤波器（降低开关噪声与纹波）
- LED 驱动电源与小功率电源模块
- 工业与消费类电子中对体积与电磁兼容有要求的场合
六、选型与使用建议
- 电流裕量：为避免电感值显著降低，建议工作电流控制在额定电流的 70%–90% 范围内，关键应用可进一步降低至 60% 左右。
- 温升与散热：考虑到 DCR 带来的铜损，若长期高负载运行应优化 PCB 走铜与散热路径。
- 测试条件：在设计验证阶段，应在目标工作频率和电流下实测电感与损耗，确认热压降与电感衰减情况。
七、焊接与储存注意
- 建议按行业标准回流焊工艺（参考 J-STD-020）进行贴片回流，避免超出推荐温度曲线的多次高温循环。
- 储存时避免高湿环境，建议密封防潮包装并在规定时间内回流焊接使用。

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.
