FTC322512S1R5MBCA 产品概述
一、产品简介
FTC322512S1R5MBCA 是 cjiang（长江微电）推出的一款功率级表面贴装电感，额定电流高、体积小巧，适用于开关电源、点对点电源模块及高频降压应用。外形尺寸 2.5 × 3.2 mm，适配高密度贴片组装与自动化生产，面向需要大电流及低损耗的移动和消费类电子产品。
二、主要参数
- 电感值：1.5 μH（±20%）
- 额定电流（Irms）：4.7 A
- 饱和电流（Isat）：5.1 A（典型值）
- 直流电阻（DCR）：37 mΩ
- 封装：SMD，尺寸 2.5 × 3.2 mm 这些参数表明器件在较高直流通过条件下仍能保持较低的压降与良好的磁性稳定性。
三、特性与优点
- 高电流承载：4.7A 额定电流与 5.1A 饱和电流可满足大电流开关点需求，降低线损和温升。
- 低 DCR：37 mΩ 降低功率损耗，有利于提高系统效率与续航能力。
- 小型化封装：2.5×3.2mm 适合空间受限的布局，同时便于自动化贴装与回流焊流程。
- 稳定性：在典型工作区域内保持磁通不易饱和，适合高频开关工作点。
四、典型应用
- 同步降压（buck）转换器输入/输出滤波
- 电源模块（POL）与点对点供电
- 汽车电子辅助电源（满足相应测试条件下）
- 高密度主板、电源管理板及便携设备
五、选型与使用注意事项
- 电感值公差 ±20%，在对纹波、共模阻抗有严格要求的电路中需进行裕量设计或选用更高精度型号。
- 额定电流指长期允许通过的电流，若长期工作接近 Irms，应评估温升与散热条件；Isat 为磁饱和边界，短路或冲击电流应控制在此值以下以避免 inductance 降低。
- DCR 对热耗与效率影响显著，系统热设计应考虑 PCB 散热与周围元件的热耦合。
六、封装与焊接建议
- 推荐采用符合厂家推荐的焊盘尺寸与制造公差，以保证焊点可靠性和电气连接性能。
- 建议遵循无铅回流焊曲线，严格控制峰值温度与时间，避免过高温度造成磁芯性能退化。
- 在布局布线时，应尽量缩短输入/输出回路，降低寄生电感与噪声耦合。
七、可靠性与测试
- 在产品验证阶段建议进行温升测试、浪涌电流试验与焊接可靠性试验（如热循环、机械冲击），并根据实际应用定制额外应力测试。
- 对于汽车级或工业级应用，需参考更严格的环境与振动测试规范。
FTC322512S1R5MBCA 以其高电流承载能力、低 DCR 与小型化包装，适合在空间受限且对效率和电流承载要求高的电源设计中使用。选择时结合实际纹波、电流裕度与热管理要求，以确保系统长期稳定运行。

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.
