FXL0650-150-M 产品概述
一、产品概况
FXL0650-150-M 为长江微电（cjiang）推出的一体成型功率电感，标称电感值 15 μH，公差 ±20%。封装为 SMD，外形尺寸 6.6 × 7.0 mm，适用于中等功率密度的开关电源与滤波电路。器件结构为一体成型（molded）设计，具有良好的机械强度与抗振动能力，便于表面贴装自动化生产。
二、关键电气参数
- 电感值：15 μH（±20%）
- 额定电流：3.1 A（允许持续通过且满足温升规范）
- 饱和电流（Isat）：4.0 A（超过该电流电感量会显著下降）
- 直流电阻（DCR）：90 mΩ
- 类型：一体成型功率电感（SMD）
三、性能计算与注意事项
- 在额定电流 3.1 A 下的铜耗（I²R）: P = I²·R ≈ 3.1² × 0.09 ≈ 0.865 W。该功耗会导致较明显的温升，布局时需考虑散热与环境温度。
- 存能量（在 Isat=4 A 时）：E = 1/2·L·I² = 0.5×15e-6×4² ≈ 0.12 mJ；在额定电流 3.1 A 时约 0.072 mJ。
- ±20% 公差意味着实际电感范围大致 12–18 μH，设计滤波或谐振时应留足裕量。关于 Isat 和额定电流的具体定义（如跌落到多少比例为 Isat）请参见厂方数据手册。
四、典型应用场景
- 同步/非同步降压（buck）电源的输出电感或电流滤波
- LED 驱动电源、ASIC/FPGA 供电点（POL）模块（中等功率）
- 工业控制、电池管理系统的滤波与能量储存
- EMI 滤波与电源去耦场景（需注意 DCR 对效率的影响）
五、选型与设计建议
- 若系统对效率与温升敏感，建议选用 DCR 更低或电流裕量更大的型号，或降低实际通过电流以减少 I²R 损耗。
- 在降压拓扑中，确保峰值电流与连续电流不超过 Isat，否则电感量会下降影响纹波与稳定性。
- 考虑电感公差带来的频域响应变化，必要时在仿真中用最坏情况（最低电感）验证性能。
六、焊接与可靠性建议
- 建议使用常规回流焊工艺（遵循 JEDEC/IPC 指南），避免长时间局部过热以免影响内部树脂及磁芯。
- 装配时避免器件受到弯曲或侧向冲击，应留有适当机械支撑。
- 若长期暴露在高湿环境，按贴片元件防潮处理（密封包装、回流前烘烤）可提高可靠性。
七、包装与储存
- 建议在原包装密封条件下保存，避免高温高湿与强光照射；若无法确认湿敏等级（MSL），按常规干燥箱处理进行回流前预烘烤。
八、总结
FXL0650-150-M 以 15 μH、4 A 饱和电流及一体成型 SMD 结构，适合中等功率的开关电源与滤波应用。DCR 90 mΩ 在功率损耗上需要设计上特别注意散热与效率折衷；选型时应结合系统电流、效率目标和电磁兼容要求综合评估。欲获取更详尽的频率响应、温升曲线和包装信息，请参考厂方数据表或联系长江微电技术支持。

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.
