FTC303020D2R2MBCA 产品概述
一、产品简介
FTC303020D2R2MBCA 为长江微电（cjiang）推出的一款功率电感，规格为 2.2µH ±20%，面向高密度开关电源与点式负载（PoL）供电场景。器件采用表面贴装（SMD）3×3mm 小封装，兼顾高电流承载能力与 PCB 布局空间受限时的应用需求。
二、主要性能参数
- 电感量：2.2 µH ±20%
- 额定电流（Irated）：4.7 A（持续工作电流建议按额定电流选型）
- 饱和电流（Isat）：6.0 A（直流偏置下电感下降到初始值一定比例时的参考值）
- 直流电阻（DCR）：约 37 mΩ（典型）
- 封装形式：SMD，外形尺寸 3.0 × 3.0 mm
- 品牌：cjiang（长江微电）
- 型号：FTC303020D2R2MBCA
三、性能特点
- 小封装大电流：3×3mm 的紧凑尺寸适合高密度布局，同时额定电流 4.7A、饱和 6A，满足中高电流降压应用。
- 低损耗：典型 DCR 仅 37 mΩ，有利于降低铜损与提升转换效率。
- 良好直流偏置特性：在高电流工况下仍保持较稳定的电感值，适用于大电流脉冲场景。
- 表面贴装便于自动化生产，适配回流焊工艺。
四、典型应用
- 同步降压（buck）和升压（boost）转换器的电感元件
- 点式负载（PoL）电源模块、VRM
- 电池供电设备与电源管理模块
- LED 驱动与电动工具电源（视实际环境温升与老化要求）
- 通信及工业电源模块
五、选型与布板建议
- 留有裕量：普通设计建议以饱和电流（Isat）或更高值的 1.2×额定电流为参考，考虑脉冲峰值与温升影响。
- 布局靠近开关器件和输入/输出电容，最小化电流回路面积以降低 EMI。
- 加强散热：若长期接近额定电流工作，建议在产品布局上提供散热路径或过孔以降低温升。
- 焊接工艺：遵循元件回流温度曲线，避免过高峰值温度影响电感性能与可靠性。
六、可靠性与封装注意
- 封装为 SMD（3×3mm），适配带卷包装（Tape & Reel）以便自动贴装。
- 满足常见的焊接和机械可靠性要求，建议在高震动或高温场合做额外验证。
- 使用环境下注意自发热与环境温度累加，长期高温会影响电感稳定性与寿命。
七、采购与技术支持
- 型号完整为 FTC303020D2R2MBCA，品牌 cjiang（长江微电）。订购时请确认规格书中的温度范围、安装尺寸图和回流焊温度曲线。
- 如需样品、批量报价或更详尽的电感频率特性、纹波电流测试数据，建议联系供应商或官方技术支持获取最新数据手册与检验报告。
如需基于具体电路（开关频率、输入/输出电压、纹波电流等）进行更精确的选型与热设计建议，可提供电路参数以便进一步评估。

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.
