FXL0420-1R2-M 产品概述
一、产品简介
FXL0420-1R2-M 是长江微电（cjiang）推出的一体成型功率电感，封装为SMD，外形尺寸约为4.2×4.4mm。该器件以紧凑体积实现较高电流处理能力，适合开关电源与各类电源管理模块中作为储能与滤波元件使用。
二、主要参数
- 电感值：1.2 µH，公差 ±20%
- 额定电流：6 A（连续工作时的建议电流）
- 饱和电流（Isat）：7 A（在此电流附近电感量明显下降，应避免长期工作在高于饱和电流的状态）
- 直流电阻（DCR）：约 27 mΩ
- 类型：一体成型功率电感（SMD）
三、性能特点
- 低DCR：27 mΩ 的低直流电阻有助于降低导通损耗，提高转换效率，适合高效率要求场合。
- 高电流能力：6A 的额定电流与 7A 的饱和电流确保在中高功率密度设计中稳定工作。
- 小型化封装：4.2×4.4mm 的SMD封装利于高密度PCB布局与自动贴装生产。
- 机械与热稳定：一体成型结构增强了抗振动与长期可靠性（具体环境温度范围及寿命数据请参见厂商详细资料）。
四、典型应用
- 同步降压（Buck）转换器输出滤波与储能
- 输入滤波与总线去耦（DC-DC 模块）
- LED 驱动电源与便携设备电源管理
- 汽车电子、通信设备与工业电源（需根据实际环境与认证确认）
五、PCB布局与焊接建议
- 建议近电源开关器件（MOSFET/DCM）布置，缩短电流回路以降低辐射与损耗。
- 为散热考虑，电感下方及周边可配合铜箔散热路径，必要时加大焊盘面积。
- 遵循无铅回流焊曲线与元件制造商的焊接工艺建议，避免高温长时滞留导致性能退化。
六、可靠性与使用建议
- 避免长期在接近或超过 Isat 的电流下工作，以免电感量下降影响系统稳定性。
- 实际设计中应考虑温升与电流重叠（峰值电流与频率）对 DCR 与寿命的影响，必要时进行热仿真或实测验证。
- 选型时结合输入/输出电流波形、允许电流纹波与效率目标，视需要留有安全裕量。

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.
