FTC201212SR47MBCA 产品概述
一、产品简介
FTC201212SR47MBCA 为长江微电（cjiang）出品的一款贴片功率电感，标称感值 470 nH，精度 ±20%，采用常见的 0805/2012 公制封装（约 2.0 × 1.25 mm）。该器件面向中大电流开关电源与滤波应用，设计兼顾低直流损耗与较高的电流承载能力，适合空间受限但对能效有要求的电源模块。
二、主要电气参数
- 感值：470 nH（±20%）
- 额定电流（Ir）：5.5 A（长期允许工作电流，按温升及性能要求确定）
- 饱和电流（Isat）：6 A（磁芯在此电流附近出现明显感值下降）
- 直流电阻（DCR）：约 20 mΩ（低 DCR 有利于降低铜损与提升转换效率）
- 封装：0805（2012 公制）
三、封装与结构特点
- 小尺寸表贴封装，适用于自动化贴片与回流焊工艺；
- 内部采用低损耗磁芯与粗导线绕制，保证较高的电流承载与较小的 DCR；
- 表面涂层与端电极经过回流与焊接相容性优化，便于 SMT 生产线集成。
四、典型应用场景
- 同步/非同步降压（Buck）转换器的输出滤波与能量储存；
- 电源模块、负载开关、LED 驱动与车载电子的电流滤波；
- 高频开关场合的 EMI 抑制与电磁兼容设计。
五、选型与设计注意事项
- ±20% 容差适合滤波或通用用途，若需精确谐振或严格电感配对，请选择更小容差产品；
- 额定电流为长期参考值，设计时需考虑工作环境温度与散热条件；Isat 为避免磁饱和的关键参数，应确保峰值电流低于 Isat。
- DCR 20 mΩ 在较高电流下仍有一定损耗，计算功耗与温升时应并入热仿真或实测数据。
六、PCB 布局与焊接建议
- 将电感放置于开关管或二极管附近，尽量缩短信号回路以降低 EMI；
- 输入输出电容靠近电感两端布置，减小回流环路面积；
- 对于较大电流路径，采用宽铜箔或多层过孔（thermal vias）以改善散热；
- 按供应商推荐的回流曲线进行焊接，避免过高的峰值温度造成性能退化。
七、可靠性与测试
- 在实际应用前建议进行温升、IR 试验、冲击振动与湿热循环等可靠性验证；
- 关注在高温或高电流工况下的感值漂移及 DCR 变化，确认满足系統寿命期望。
八、采购与替代建议
- 适合追求性价比及中等精度电源设计的项目；如需更低 DCR、更高 Isat 或更小体积，可考虑更大封装或其他功率电感系列。
- 购买与选型时建议索取长江微电的详细数据手册（Datasheet）与样品以开展验证测试。

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.
