FTC201208SR47MBCD 产品概述
一、产品简介
FTC201208SR47MBCD 是长江微电（cjiang）推出的一款小型功率贴片电感，适用于中高电流点对点电源滤波和DC-DC降压模块。主要参数如下：
- 电感值：470 nH，公差 ±20%
- 额定电流：4.7 A
- 饱和电流（Isat）：5.2 A
- 直流电阻（DCR）：24 mΩ
- 封装形式：SMD，外形尺寸 1.2 × 2.0 mm
该器件在体积极小的同时提供较高的额定电流与较低的DCR，适合空间受限且对效率有较高要求的移动设备和板载电源设计。
二、主要性能特点
- 小型化：1.2×2.0 mm 超小封装，有利于高密度PCB布板与紧凑电源模块设计。
- 高电流承载能力：额定电流4.7 A，饱和电流5.2 A，可满足点负载和多相供电的电流需求。
- 低直流损耗：DCR 24 mΩ，有助于降低导通损耗与发热，提高系统效率。
- 可靠性：适配回流焊工艺的表面贴装封装，便于SMT批量生产。
三、典型应用场景
- 手机、平板、可穿戴设备的DC-DC降压转换器（点对点电源）
- 多相CPU/GPU供电模块与电源管理IC（PMIC）配套线圈
- LED 驱动、电机驱动与通信设备的滤波与储能
- 高密度电源模块、汽车电子低功耗电源（依据认证与工作温度）
四、布局与使用建议
- 布局：电感应尽量靠近开关芯片（例如MOSFET或PMIC）与电感输入/输出节点，缩短高频回流路径，减小寄生阻抗。
- 散热：由于在高电流与纹波条件下会产生热量，建议保证底层有连续地线或散热铜箔并适当开孔、加焊盘以利散热。
- 电流余量：实际设计时应考虑纹波电流和环境温度对电感温升与饱和的影响，避免长期工作在接近Isat的状态以保持感值稳定。
- 焊盘设计：按照厂家推荐焊盘尺寸与回流曲线，避免过度应力引起焊点裂纹或器件移位。
五、选型与注意事项
- 若应用中存在较大纹波电流或瞬态峰值，建议选型时留有裕量（使实际峰值低于Isat），并关注在高温下的电感衰减。
- 对效率要求高的系统，优先考虑DCR更低或体积允许下电流等级更高的器件。
- 若需通过汽车或工业级认证，请与厂商确认器件的温度等级、湿热与振动可靠性测试报告。
六、结论
FTC201208SR47MBCD（cjiang/长江微电）以其470 nH、4.7 A 额定电流与5.2 A 饱和电流，以及1.2×2 mm 的超小封装，为空间受限且需承载中高电流的电源系统提供了一个平衡尺寸与性能的解决方案。在实际应用中，注意电流裕量、散热设计与PCB布线，可以充分发挥其功率电感的性能优势。若需更详细的电气特性曲线、温升数据或推荐焊盘，请联系供应商获取完整数据手册。

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.
