FTC303012D100MBCA 产品概述
一、产品简介
FTC303012D100MBCA 是长江微电（cjiang）推出的一款功率电感，封装为 SMD 3×3mm，标称电感值 10 μH，公差 ±20%。该器件面向开关电源与电源滤波应用，设计额定电流为 2.3 A，饱和电流（Isat）同为 2.3 A，直流电阻（DCR）约为 220 mΩ。
二、主要特性
- 电感值：10 μH（±20%），适用于中低频开关变换场合；
- 额定/饱和电流：2.3 A，满足中等电流的瞬态与持续供电需求；
- DCR：220 mΩ，直流损耗明显，需关注热耗和压降；
- 封装：SMD，3×3 mm，适合高密度 PCB 布局与自动贴装工艺；
- 品牌：长江微电（cjiang），适合对成本与批量一致性有要求的项目。
三、性能提示（计算与影响）
- 在额定电流 2.3 A 时，直流损耗约为 P = I^2·DCR ≈ 2.3^2×0.22 ≈ 1.16 W；
- 电压降约为 V = I·DCR ≈ 2.3×0.22 ≈ 0.51 V；
以上数值表明在持续满载工作时器件发热与电压损耗较大，建议在系统选型与热设计时充分考虑并留有余量或采取散热/并联方案。
四、典型应用
- 降压（Buck）开关电源的功率电感；
- 电源输入滤波与输出滤波；
- LED 驱动、电池供电设备的能量存储与纹波抑制；
- 工业与通信设备中需要中等电流过滤与储能的场合。
五、选型与使用建议
- 若系统连续输出接近或超过 2.3 A，建议选择更低 DCR 或更高额定电流的电感，或采用并联方案以降低损耗与温升；
- 注意电感公差 ±20% 带来的实际值偏差，关键回路应在仿真或样机上验证纹波与控制环稳定性；
- PCB 布局应缩短电感与开关器件间的回流路径，增大铜箔散热面积以降低温升；
- 过流与高温工作场景应留有热裕量，避免长期工作在接近饱和电流的条件下。
六、封装与可靠性
3×3 mm SMD 封装适合自动化贴装与回流焊工艺，建议参考厂商推荐回流曲线和贴装注意事项（防止过度机械应力、焊接时避免超过温度极限）。出货包装、检验与批号信息请向供应商确认，以便质量追溯。
七、采购与替代
型号：FTC303012D100MBCA（长江微电 cjiang）。如需更低损耗或更高电流能力，可参考同类尺寸下的低 DCR 或更大截面积绕线产品，或询问厂商是否有同系列的更高规格型号。
上述为该型号功率电感的概述与实用建议，选型时请结合实际电路条件、热环境与寿命要求进行综合评估，并以样品测试结果为准。

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.
