FTC303015D4R7MBCA 产品概述
一、产品简介
FTC303015D4R7MBCA 是长江微电（cjiang）推出的一款小型化一体成型 T‑CORE 功率电感。标称电感值 4.7µH，公差 ±20%，额定电流 3.5A，饱和电流（Isat）4.0A，直流电阻（DCR）约 87mΩ。器件采用扁线工艺和一体成型结构，体积小、封装为 SMD 贴片（3×3mm），适合高密度、自动化装配的电源应用场合。
二、主要特性
- 电感值：4.7µH ±20%，适用于中低频滤波与能量传输。
- 电流能力：额定 3.5A，饱和 4.0A，满足多数 DC‑DC 降压与升压转换器的连续工作要求。
- 低频损耗与稳定性：扁线与 T‑CORE 结构在中频范围内表现出较好的磁通承载能力与温度稳定性。
- 封装与工艺：SMD 3×3mm 小型封装，适配回流焊与高速贴片生产线，便于在空间受限的模块中应用。
- 可靠性：一体成型结构增强了机械强度和耐振动性能。
三、典型应用
- 开关稳压器（buck/boost）输出滤波电感
- 移动电源、便携设备的电源模块
- LED 驱动与电源管理模块
- 网络设备与通信终端的电源滤波
- 工业控制中低功率 DC‑DC 转换器
四、设计与选型建议
- 电流余量：为避免磁饱和和过热，建议工作电流在额定电流的 70%–90% 范围内选择，长时间接近额定值时应考虑散热与温升。
- 饱和裕度：若电路存在瞬态电流峰值，请确保峰值低于 Isat（4A），或增加缓冲电路以减小涌流影响。
- DCR 考虑：87mΩ 的直流电阻会带来一定功率损耗，计算时应考虑 I²R 损耗并评估温升对电感值漂移的影响。
- 布局与焊盘：建议靠近开关元件放置，缩短回流路径以减少 EMI；采用厂方建议的推荐焊盘和过孔布局以保证热和电连接可靠。
五、封装与采购
- 封装形式：SMD 贴片，3×3mm，适配标准贴片工艺与自动化装配。
- 包装方式：常见为卷带（tape‑and‑reel），便于贴片机取放。
- 品牌：长江微电（cjiang），适合要求小型化与批量生产的客户选型。
六、注意事项
- 请根据实际工作环境（温度、散热条件）对电感工作电流进行适当降额。
- 在高频或高纹波场合，建议结合测量或仿真验证电感在目标频段的实际阻抗特性和损耗。
- 量产前建议索取样品进行板级验证，包括温升、效率与 EMI 测试。
如需更详细的电气特性曲线、推荐焊盘尺寸或回流焊曲线，请告知，我可以协助获取或分析以便完成电路级验证与可靠性评估。

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.
