FXL0412-R47-M 产品概述
一、产品简介
FXL0412-R47-M 为长江微电（cjiang）系列一体成型功率电感，额定电感值 470 nH（±20%）。器件为表面贴装（SMD）封装，外形尺寸 4.2×4.4 mm，针对中高电流开关电源与电能滤波场合优化设计。该器件在保持小体积的同时，提供高额定电流与较低直流电阻，适用于空间受限但要求高效率的电源设计。
二、主要性能参数
- 电感值：470 nH ±20%
- 额定电流（Irated）：6 A（连续工作推荐值）
- 饱和电流（Isat）：6.8 A（定义：电感下降至初始值一定比例时的电流点）
- 直流电阻（DCR）：21 mΩ（典型值）
- 封装/尺寸：SMD，一体成型，4.2×4.4 mm
- 类型：功率电感 / 模压型（molded）
三、产品特点（要点）
- 高电流能力：6 A 连续额定电流与 6.8 A 饱和电流，适合中小功率转换器。
- 低损耗设计：21 mΩ 低 DCR 有利于降低 I²R 损耗，提升转换效率并减小发热。
- 小型化封装：4.2×4.4 mm 带来板级空间节省，便于高密度布局。
- 机械可靠：一体成型结构抗振动、耐潮湿，适合工业与车载环境（具体认证请参见厂商资料）。
四、典型应用
- DC–DC 降压/升压转换器（buck、boost）
- 电源模块与 point-of-load (POL) 供电
- LED 驱动电源与便携设备电源管理
- 网络设备、通信与工业电源滤波
- 对空间、效率与成本有综合要求的消费电子与工业产品
五、使用与布局建议
- 布局：电感与功率开关、肖特基/同步整流器尽量靠近，走线短而宽以降低寄生阻抗。
- 散热：虽为低 DCR 器件，高纹波电流仍会产生热量，建议在高功率或高环境温度下增加铜铺或散热通孔以改善散热。
- 直流偏置效应：电感值随通过电流增加会下降（直流磁饱和/偏置效应），设计时留有裕量，必要时参考厂方提供的 L–I 曲线与温升曲线。
- 焊接：兼容常规回流工艺，建议遵循制造商的回流曲线与焊盘推荐尺寸，避免过度热循环或机械应力。
六、选型要点
- 按开关频率选择电感量：470 nH 适用于中高频开关电源，需根据纹波电流与输出电压计算峰峰纹波。
- 考虑电流裕量：额定电流 6 A 为长期连续工作建议值，纹波峰值或瞬态电流应低于 Isat 并保留一定裕量以防止饱和。
- 效率优化：若对效率要求更高，应优先考虑更低 DCR 或更大封装的型号以降低损耗。
七、结语
FXL0412-R47-M 以其紧凑尺寸、低 DCR 与高电流能力，适合多种中小功率电源与滤波场合。在实际应用中，请结合具体开关频率、纹波电流与热环境，参考长江微电的完整规格书（Datasheet）与 L–I、热阻特性曲线完成最终设计与可靠性验证。若需替代方案或更多电感值/封装选型建议，可提供电路参数以便给出针对性推荐。

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.
