FTC201612SR47MBCA 产品概述
一、产品简介
FTC201612SR47MBCA 为长江微电（cjiang）出品的一款功率电感，封装为贴片 SMD，外形尺寸约 1.6×2.0 mm，标称电感值 470 nH（±20%），额定电流与饱和电流均为 6.7 A，直流电阻（DCR）约 13 mΩ。该器件针对空间受限且需处理较大直流/脉冲电流的移动电源、消费类与通信电源方案优化设计。
二、主要电气参数
- 电感值：470 nH，公差 ±20%
- 额定电流（Irated）：6.7 A
- 饱和电流（Isat）：6.7 A（定义为电感下降到额定值的指定比例时的电流）
- 直流电阻（DCR）：约 13 mΩ
- 封装：SMD，尺寸 1.6×2.0 mm
三、产品特点
- 小体积高电流：1.6×2.0 mm 封装下支持 6.7 A，适合高密度电源模块。
- 低损耗：13 mΩ 低 DCR 降低导通损耗与发热，有助于提高系统效率。
- 良好抗磁饱和性能：较高的 Isat 能保证在大电流脉冲条件下维持电感特性，避免电流峰值导致性能退化。
- 贴片封装：适配自动化回流焊工艺，便于批量装配。
四、典型应用场景
- DC-DC 开关稳压器（降压、升压转换器）的输入/输出滤波与能量储存；
- CPU、GPU、FPGA 及功率管理模块的电源滤波；
- 通信设备、车载电子、工业电源以及便携式设备的电源子系统。
五、选型与布局建议
- 额定电流与实际最大连续/脉冲电流应留有裕量，建议实际工作电流 ≤ 70–80% Irated，以控制温升与防止接近饱和。
- 对于大电流路径，尽量缩短布线并增加铜厚及过孔数量以降低等效串联电阻与寄生电感。
- 器件应靠近开关管或稳压芯片放置，并在关键信号路径处保持良好地平面与旁路电容的配合。
- 回流焊工艺请遵循厂方推荐的温度曲线，避免超过材料的最高回流温度。
六、可靠性与测试
- 建议在目标应用环境下进行温升测试与长期高温循环老化验证，关注在额定电流下的温度上升与电感漂移。
- 进行冲击、振动及热循环试验，确认在极端工况下的机械与电气稳定性。
- 对于高频应用，应测量频率响应与磁饱和曲线，验证在工作频率下的有效电感与损耗。
七、采购与替代方案
FTC201612SR47MBCA 适用于对体积和电流能力有双重要求的电源设计。采购时注意批次一致性与器件源头可追溯性。若需替代，可选取在尺寸、电感值及 Isat/DCR 等关键参数接近的产品，但务必验证在目标电路中的温升与饱和行为。
结语：该型号以小尺寸、高电流与低 DCR 为优势，适合高密度电源模块场景，在选型与 PCB 布局上给予适当裕度与热管理，能显著提升系统效率与可靠性。

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.
