FXL0518-1R5-M 产品概述
一、产品简介
FXL0518-1R5-M 是长江微电（cjiang）推出的一款一体成型表面贴装功率电感，额定应用于中高电流开关电源与点对点电源模块。器件体积紧凑（封装约 5.2×5.4 mm），兼顾高电流能力与低损耗，适用于对体积、效率与可靠性有较高要求的电源设计。
二、关键参数
- 电感值：1.5 μH，公差 ±20%
- 额定电流：7.5 A（连续载流能力）
- 饱和电流（Isat）：9 A（典型标称）
- 直流电阻（DCR）：约 26 mΩ（典型）
- 类型：一体成型功率电感（SMD）
- 封装尺寸：5.2 × 5.4 mm
三、主要特性与优势
- 高电流承载：7.5 A 额定电流配合 9 A 饱和电流，适合降压转换器、同步整流及点对点供电场景。
- 低 DCR：约 26 mΩ 的直流电阻有助于降低导通损耗，提高转换效率并减小发热。
- 一体成型结构：机械强度高、温漂小、抗振动性能好，方便自动化贴装和回流焊工艺。
- 紧凑封装：5.2×5.4 mm 的小型封装便于高密度布板设计，节省 PCB 面积。
四、典型应用
- 开关稳压器（降压/升降压）电感
- 顶级 CPU/GPU 点对点电源滤波
- 电源模块、DC-DC 模块输入/输出滤波
- 通信设备、电动工具及工业电源板卡
五、封装与安装
本器件为 SMD 封装，推荐采用常规回流焊工艺。焊盘设计应保证良好散热与可靠焊接，遵循制造商提供的 PCB 推荐焊盘尺寸与回流曲线，以避免热应力和机械应力集中。对于高功率应用，建议在布局上为电感周围留有良好散热路径。
六、使用建议与注意事项
- 额定电流为长期连续工作限制，建议在实际设计中考虑一定裕度（例如 10–20%）以延长寿命并降低温升。
- 饱和电流为磁芯进入非线性区的参考值，接近或超过 Isat 时电感量会显著下降，应避免长期运行于饱和区。
- 高频纹波电流与峰值电流对损耗、温升和电感值影响较大，设计需综合评估涌流与温度升高。
- 储存与贴装过程中注意防潮与抗静电保护。
七、品质与可靠性
长江微电器件通常经过电气性能、温度循环、机械振动及回流焊后可靠性测试。实际量产前建议与供应商确认完整数据手册、温升曲线、频率响应（阻抗曲线）及寿命测试报告，以满足量产与验收要求。
如需更详细的电气曲线、推荐 PCB 焊盘或样片测试支持，请联系供应商或索取 FXL0518-1R5-M 的完整规格书。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
