FXL1040-150-M 产品概述
一、产品简介
FXL1040-150-M 为长江微电（cjiang）推出的一体成型功率电感，标称电感量 15 µH（精度 ±20%），额定电流 6.5 A，饱和电流 Isat 7 A，直流电阻（DCR）约 45 mΩ。器件为表面贴装（SMD），外形尺寸 11.5 × 10 mm，适合要求高电流、可靠性强的开关电源与电源滤波场合。
二、主要性能与特点
- 高电流承载能力：额定电流 6.5 A，短时饱和电流 7 A，适合中大电流点负载应用。
- 低 DCR：45 mΩ 的直流电阻可降低导通损耗，提升效率与发热控制空间。
- 一体成型结构：提高机械强度与抗震动能力，适合贴片自动化生产。
- 紧凑 SMD 封装：11.5×10 mm 的体积在功率密度要求较高的 PCB 上易于布局。
- 宽容差（±20%）：便于在滤波与能量储存类电路中成本与性能的平衡。
三、电气与热设计要点
- 饱和与纹波电流：设计时应保证工作峰值电流低于 Isat，以免电感值显著下降影响环路稳定。
- 损耗与温升：依据 DCR 计算 I^2·R 损耗，评估长期温升并留有余量；并注意器件在高温下 DCR 可能上升。
- 布局建议：电感尽量靠近开关器件和输出电容布局，输入输出走线短且宽，增设热铜箔和过孔以利散热。
- 焊接可靠性：采用无铅回流工艺，遵循厂商推荐的回流曲线；避免二次温度冲击影响结构完整性。
四、典型应用场景
- 同步降压（Buck）及升降压（SEPIC、Boost）电源的能量储存与输出滤波。
- 点（Point-of-Load）电源模块、CPU/FPGA 的次级供电滤波。
- 通信、工控与消费电子中对中等电流且体积受限的电源解决方案。
- LED 驱动与电机驱动中的滤波与能量处理。
五、选型与使用建议
- 按最长工作周期内电流峰值与纹波电流选型，必要时选用额定电流有更大裕度的型号。
- 若对电感精度要求高，应考虑并联/串联或选用更高精度器件以降低设计不确定性。
- 在版图上为电感提供适当的热散路径，关键焊盘尽量做大且靠近过孔并联铜柱。
- 采购时确认环境温度范围与寿命、备份元件规格以满足产品可靠性需求。
六、包装与订购
型号：FXL1040-150-M；品牌：cjiang（长江微电）；封装：SMD，11.5×10 mm；关键参数：15 µH ±20%，额定电流 6.5 A，Isat 7 A，DCR 45 mΩ。订购时请向供应商确认最低起订量、包装形式（卷带/托盘）及最新的器件数据手册以获取完整的焊接与环境规范。

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.
