FTC252012SR47MBCA 产品概述
一、产品简介
FTC252012SR47MBCA 是长江微电（cjiang）推出的一款功率电感，标称电感值 470 nH，公差 ±20%，封装为 SMD（尺寸约 2.0 × 2.5 mm）。该器件面向高密度开关电源和点电流管理场景，额定电流 6.5 A，饱和电流（Isat）7.5 A，直流电阻（DCR）约 13 mΩ，适合中高电流、体积受限的电源滤波与储能应用。
二、主要电气参数与含义
- 电感值：470 nH（±20%，实际范围约 376–564 nH），适用于 MHz 级开关频率的输出滤波或能量储存。
- 额定电流：6.5 A，指在规定温升和环境下的连续工作电流能力。
- 饱和电流 Isat：7.5 A，超过此电流电感值会显著下降，影响输出稳定性与电路性能。
- 直流电阻 DCR：13 mΩ（典型），决定铜耗与热量产生。举例：在 6.5 A 下的铜损约 I^2·R = 6.5^2 × 0.013 ≈ 0.55 W，应考虑散热与温升。
三、核心特点
- 小型化封装（2×2.5 mm），利于高密度 PCB 布局与多通道并列设计。
- 高额定电流与较大 Isat，适合点负载（POL）转换器与同步降压拓扑。
- 低 DCR，有利于降低导通损耗并提高转换效率。
- 适配自动贴装与回流焊工艺，便于量产。
四、典型应用场景
- 通信、服务器及电源模块的点式电源（POL）输出滤波。
- 手机、平板、笔记本等便携设备的 DC-DC 降压（Buck）电感。
- LED 驱动、电池管理系统及工业控制电源。
- 多相供电系统中用于每相输出储能与滤波。
五、选型与使用建议
- 连续电流选择：建议长期工作电流不超过额定 6.5 A；为保证裕度和温升考虑，可将设计连续电流控制在 80–90% 的范围内（约 5.2–5.9 A），并对瞬态浪涌比对 Isat（7.5 A）做好裕量评估。
- 热管理：由于在高电流下损耗可达数百毫瓦至瓦级，应采用足够铜面积的焊盘、尽量短的引线和必要的散热铜箔/过孔来降低温升。
- 布局：输入/输出回路尽量缩短环路，电感引脚与 MOSFET、电容之间走短而粗的铜线；若多层板，可在电感下方安排地平面或热通孔以增强散热。
- 焊接工艺：推荐遵循标准无铅回流曲线（参照 IPC/JEDEC），避免重复高温循环；回流后若需清洗请使用兼容材料的溶剂，避免腐蚀磁芯涂层。
六、可靠性与注意事项
- 避免在超出 Isat 的条件下长期工作，以免电感饱和导致电路失稳或器件过热。
- 电感为无隔离器件，不用于需要电气隔离的场合。
- 在高温或高湿环境下应注意器件的磁性能漂移与 DCR 增大，设计时留有余量并进行实际温升测试。
该器件以其小尺寸、高电流与低 DCR 的特性，适合要求体积受限且效率优先的电源设计场合。选择与布局时注重散热与饱和裕量，可显著提升整体系统性能与可靠性。

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.
