FNR6028S680MT 产品概述
一、产品简介
FNR6028S680MT 是长江微电（cjiang）推出的一款 SMD 功率电感，封装规格为 6×6 mm，属于磁胶屏蔽结构。标称电感值 68 μH，公差 ±20%，额定电流与饱和电流均为 950 mA，直流电阻 (DCR) 为 468 mΩ。该器件针对中低频电源滤波与能量储存场合设计，兼顾体积、屏蔽性与成本。
二、主要参数
- 电感值：68 μH ±20%
- 额定电流：950 mA
- 饱和电流 Isat：950 mA（电感下降到规定比例时的电流）
- 直流电阻 DCR：468 mΩ
- 类型：磁胶屏蔽电感（屏蔽型，降低磁串扰）
- 封装：SMD，6 × 6 mm
- 品牌：cjiang（长江微电）
三、产品特点
- 小型化封装（6×6 mm），适合表贴自动化装配；
- 屏蔽结构，有利于降低外泄磁通，减小对邻近器件的干扰；
- 较高的电感值（68 μH）适合输出滤波与储能；
- DCR 较大，意味着在高电流下有较明显的功耗与发热，需要注意功率损耗管理；
- 额定电流与饱和电流标称相同，实际使用时应考虑电感随直流偏置下降的情况并留有裕量。
四、典型应用场景
- 开关稳压器（如降压/升压转换器）中的输出滤波或储能电感；
- LED 驱动与直流电源滤波；
- EMI/EMC 抑制、噪声滤波回路；
- 电池供电设备的电源管理与能量缓冲（如便携式设备、电源模块）。
五、布局与装配建议
- 贴片安装，靠近电源芯片放置以缩短回流路径和减小寄生环路面积；
- 保持良好的焊盘和过孔散热（若电流持续较大），并参考厂商推荐的封装尺寸与焊盘布局；
- 回流焊时遵循长江微电提供的回流曲线或通用无铅回流曲线，避免过度加热；
- 为降低温升，尽量在 PCB 上为电感和相邻 MOSFET、二极管等器件提供热量分散通道与合适的铜箔。
六、选型与使用注意事项
- 由于 DCR = 468 mΩ，在接近额定电流时功耗明显。按 P = I^2·R 估算：若持续工作电流为 0.95 A，P ≈ 0.42 W，发热需要考虑；建议连续工作电流按 60%~80% 的裕量选型，例如 0.65 A 时损耗约 0.14 W；
- 关注电感随直流偏置的下降特性，若电路对电感值敏感，应在实际工作电流下测量或咨询厂家曲线；
- 在要求极低 DCR 或更高电流承载能力的场合，应优先选择低 DCR 或更大规格的电感器件；
- 储存与装配按一般无铅 SMT 器件规范执行，避免潮湿环境影响焊接可靠性，必要时遵循厂商的防潮等级信息。

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.
