FEXL0550A-8R2M — 8.2µH 功率电感器产品概述
一、概述
FEXL0550A-8R2M 是长江微电（cjiang）推出的一款车规级 SMD 功率电感，额定电流 6.1A，饱和电流 Isat 为 7.2A，电感值 8.2µH（公差 ±20%）。封装尺寸紧凑为 5.5 × 5.3mm，直流电阻 (DCR) 仅 32.5mΩ，适合对体积与电流能力有较高要求的开关电源和滤波场合，并满足 AEC‑Q200 车规可靠性要求。
二、主要参数
- 品牌 / 型号：cjiang (长江微电) / FEXL0550A-8R2M
- 感值：8.2µH，公差 ±20%
- 额定电流（Irms）：6.1A（长期允许流过且温升在允许范围内）
- 饱和电流（Isat）：7.2A（在此电流水平电感量开始明显下降）
- 直流电阻（DCR）：32.5mΩ
- 封装：SMD，尺寸 5.5 × 5.3mm
- 车规等级：符合 AEC‑Q200
三、关键性能与优势
- 高频性能与大电流承载：在小型封装下提供 6.1A 的额定电流，适用于点对点电源和功率级滤波。
- 低 DCR：32.5mΩ 有助于降低 I^2R 损耗，提升效率与热性能。
- 高饱和电流：7.2A 的 Isat 为短时过载或突发电流提供余量，减少电感饱和导致的性能退化风险。
- 车规可靠性：通过 AEC‑Q200 认证，适合汽车电子等高可靠场景。
四、典型应用
- 开关稳压器（Buck / Boost）及点载电源（POL）滤波器
- 汽车电子电源模块、车载充电、车身控制器
- LED 驱动、电机驱动前端滤波
- 工业电源及高密度电源模块
五、使用与布局建议
- 贴片布局：尽量将电感靠近功率 MOSFET 或稳压芯片，缩小电流回路面积以减少寄生噪声。
- 热管理：考虑 DCR 带来的功耗（P = I^2·DCR），对长期大电流应用需评估温升并提供适当散热路径。
- 电流裕量：正常设计中尽量保持工作电流低于额定值 Irms，以延长寿命并避免接近 Isat。
- 焊接与回流：按器件厂商推荐的回流曲线进行焊接，避免超出温度极限。若用于车规产品，请遵循相关可靠性试验流程。
六、可靠性与采购注意
FEXL0550A-8R2M 以车规标准设计，适合对可靠性和寿命有严格要求的系统。选型时请核对目标工作温度、纹波电流和峰值电流是否满足器件额定值，并向供应商确认批次检验报告与样片测试数据以满足整机验证需求。

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.
