FTC252010S2R2MBCA 产品概述
一、产品简介
FTC252010S2R2MBCA 是长江微电（cjiang）推出的一款表面贴装功率电感，标称电感值 2.2 μH，适用于中小功率开关电源和电源滤波场合。器件体积小巧、封装为 SMD（2x2.5mm），适合空间受限的移动设备、通信和工业电子产品。
二、主要参数
- 电感值：2.2 μH，公差 ±20%
- 额定电流：2.4 A（连续允许电流）
- 饱和电流（Isat）：3.3 A（磁芯明显进入磁饱和的参考值）
- 直流电阻（DCR）：约 62 mΩ（影响铜损和效率）
- 封装：SMD，尺寸标识 2x2.5mm
三、产品特性
- 小体积高电流承载：封装紧凑但可承受数安培电流，适合用于小型降压或升压电源。
- 抗饱和能力：3.3 A 的饱和电流提高了瞬态大电流下的稳定性。
- 低 DCR：62 mΩ 有助于降低铜损与发热，提升转换效率（实际损耗与工作温度与频率有关）。
四、典型应用
- Buck/Boost DC-DC 转换器的储能电感
- 电源输出滤波与纹波抑制
- 手机、无线模块、行车电子、小型工业电源等空间受限场景的电源管理
五、设计与选型建议
- 电流裕量：为保证可靠与低温升，连续工作电流建议在额定电流以下选用，考虑环境温度与散热条件。
- 饱和与纹波：注意工作电流的峰值与直流偏置会降低实际电感值，应在目标工作点上验证感值与损耗。
- DCR 考量：62 mΩ 将带来 I^2·R 损耗，需在效率预算与热设计中计入。
- 并联与替代：如需更低 DCR 或更高电流，可考虑并联多个电感或选用更大规格器件。
六、封装与工艺注意事项
- 适用于常规无铅回流焊工艺，具体回流温度曲线请参照厂方资料以避免材料应力。
- PCB 布局建议将电感靠近开关器件与输出电容放置，增设散热铜箔与过孔以改善热传导。
- 焊盘设计应与供应商推荐封装图匹配，确保焊接可靠性与回流稳定性。
七、可靠性与测试建议
- 在最终应用中进行温升、效率、纹波和瞬态响应测试，以验证电感在实际偏置与频率下的表现。
- 关注长期热循环与机械应力对引脚焊点与磁性材料的影响，必要时参照厂方可靠性数据（如高温贮存、循环测试等）。
备注：以上为基于给定规格的产品概述，具体电气、机械和环境参数请以厂方数据手册为准；在关键设计中建议索取样品并进行实际测评。

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.
