FTC404030S1R0MGCA 产品概述
一、产品简介
FTC404030S1R0MGCA 是长江微电（cjiang）推出的一款面向中高电流电源转换与滤波场景的 SMD 片式功率电感。标称电感值 1.0 µH，公差 ±20%，封装尺寸为 4.1 × 4.1 mm，适合空间受限但需较大电流承载能力的应用。其额定电流为 10 A，饱和电流（Isat）为 15.5 A，直流电阻（DCR）约 12 mΩ，兼顾低损耗与高电流稳定性。
二、主要特性
- 电感值：1.0 µH（±20%）
- 额定电流：10 A，支持连续大电流应用
- 饱和电流：15.5 A（电感值在高电流下出现明显下降）
- 直流电阻：12 mΩ（低 DCR 有利于降低 I²R 损耗）
- 封装：SMD，外形 4.1 × 4.1 mm，适配自动贴装与回流焊工艺
- 品牌：cjiang（长江微电）
三、电气性能与损耗估算
DCR 对功率损耗影响显著。按额定电流 10 A 计算，铜损约为 P = I²·R = 100·0.012 = 1.2 W；若达到饱和电流 15.5 A，铜损将增至约 2.88 W。设计时需在散热与电流容限间权衡，避免长期运行在饱和区以保持电感值与滤波效果。
四、典型应用场景
- 同步降压（Buck）和降压-升压（Buck-Boost）开关电源的功率电感
- 输入/输出电源滤波，抑制纹波与开关噪声
- 汽车电子、工业电源与通信基站的中高电流模块
- LED 驱动、电池管理与便携电源的电流管理单元
五、封装与安装注意
该器件为 SMD 结构，推荐采用标准回流焊工艺。为了降低温升与 DCR 引起的热损，建议在 PCB 上为电感两侧焊盘配置较大铜箔并与散热层相连，必要时增加过孔将热量传导至内层或底层散热区。贴装时注意可靠的焊接湿润性与清洁度，避免长时间受潮。
六、热管理与可靠性建议
- 尽量在额定电流下短路电感工作，避免长期在接近 Isat 的电流下运行。
- 评估器件在不同环境温度下的电感衰减与 DCR 上升，必要时留有余量。
- 在高功率应用中配合合理的 PCB 铜箔面积与散热结构，以保持电感温升在容许范围内。
七、选型提示与替代
当需要更低 DCR 或更高电流余量时，可考虑更大尺寸或不同磁芯材料的器件。若空间允许，优先选择 DCR 更低的型号以降低系统总损耗。订购时请确认完整型号（FTC404030S1R0MGCA）与批号，向供应商索取详细数据手册与样品进行实测验证。
如需参考波形、频率响应或在特定拓扑下的电感变化曲线，可提供应用环境与频段，我方可协助评估并给出更具体的测试建议。

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.
