FXL0518-3R3-M 产品概述
一、产品简介
FXL0518-3R3-M 是长江微电（cjiang）推出的一款一体成型功率贴片电感，额定电感值为 3.3 µH，公差 ±20%。该器件为 SMD 封装，外形尺寸约 5.2 × 5.4 mm，专为中大电流电源应用设计，具有低直流电阻和较高的饱和电流特性，适合用于开关电源和电流滤波场合。
二、主要电气参数
- 电感值：3.3 µH ±20%
- 额定电流（Ir）：4.5 A（连续工作推荐值）
- 饱和电流（Isat）：5 A（磁芯开始显著降感时的参考值）
- 直流电阻（DCR）：约 58 mΩ
- 类型：一体成型功率电感（SMD）
三、核心特点
- 高电流承载能力：额定电流 4.5 A，饱和电流 5 A，满足中大电流转换器需求。
- 低 DCR：直流电阻 58 mΩ，有利于降低功耗和温升，提高转换效率。
- 紧凑封装：5.2×5.4 mm 小尺寸，便于高密度 PCB 布局。
- 一体成型：结构稳固，抗振动性能好，适合自动贴装与回流焊工艺。
四、典型应用
- 降压/升压 DC-DC 转换器（尤其是 2A–5A 档位）
- 电源管理模块（PMIC）与电压调节器（VRM）
- LED 驱动与电源滤波电路
- 工控与通信设备的电源输入滤波
五、设计与安装建议
- 推荐在实际应用中对额定电流进行适当降额，以控制温升并延长寿命。
- 布局时将电感尽量靠近开关器件与输出电容，缩短信号回路以降低 EMI。
- 遵循制造商推荐的 PCB 焊盘尺寸和回流焊曲线，避免过高的回流峰值温度。
- 在高温或高可靠性场合，建议做热仿真与实测验证。
六、采购信息与型号说明
- 品牌：cjiang（长江微电）
- 型号：FXL0518-3R3-M
- 封装：SMD，一体成型

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.
