FTC201608S4R7MBCA 功率电感产品概述
FTC201608S4R7MBCA是长江微电（cjiang）推出的一款小型化贴片功率电感，针对低压DC-DC转换、便携设备供电等场景设计，以紧凑封装实现中等电流承载能力，兼顾性能与体积优势，是高密度布局场景的高性价比选择。
一、产品定位与核心属性
该电感属于低压中小功率电感，核心定位清晰：
- 适配高密度PCB布局（如便携设备、小型模块）；
- 支持连续工作电流≤1.6A，峰值电流≤1.7A；
- 电感值稳定在4.7uH±20%范围内，覆盖常见降压/升压电路的储能、滤波需求。
二、关键电气参数详解
参数项 规格值 实际意义 电感值 4.7uH±20% 有效范围3.76uH~5.64uH，满足5V/3.3V供电电路的常规电感需求 额定电流（Ir） 1.6A 连续工作时电感表面温度≤125℃（典型值），避免热失控导致性能下降 饱和电流（Isat） 1.7A 电感值下降30%时的临界电流，为电路过载保护提供参考阈值（超此值电感饱和） 直流电阻（DCR） 260mΩ 低直流损耗，1.6A连续工作时功率损耗≈0.66W，减少电源效率损失 封装类型 SMD（1.6×2mm） 贴片式，兼容自动化贴装，适配小尺寸PCB布局三、物理封装与工艺特点
- 超小型封装：1.6mm（宽）×2.0mm（长），厚度约1.0mm（2016封装常规厚度），可显著节省PCB空间，适配智能手环、无线耳机等便携设备；
- 焊接兼容性：SMD封装支持回流焊、波峰焊等常规工艺，焊盘设计匹配行业标准，降低虚焊、假焊概率；
- 磁芯与绕线：采用铁氧体磁芯（兼顾电感稳定性与电流承载），铜线绕制工艺成熟，参数一致性好。
四、典型应用场景
该电感因体积小、电流适配性强，广泛应用于：
- 便携式消费电子：手机快充模块、无线耳机充电盒、智能手环的3.3V/1.6A降压电路；
- 小型电源模块：USB-C接口5V/1A适配器、IoT终端低功耗供电单元；
- LED驱动电路：小功率LED串（如手机闪光灯辅助驱动、智能台灯恒流驱动）；
- 物联网终端：传感器节点、蓝牙模块的MCU供电电路（适配STM32L等低功耗MCU）；
- 车载辅助电路：非车规级车载小设备（如点烟器USB扩展器）的供电滤波。
五、选型与使用注意事项
- 电流匹配：
- 连续工作电流不得超过1.6A（避免长期过流导致电感老化）；
- 峰值脉冲电流不得超过1.7A（防止电感饱和，导致电感值骤降、电路效率下降）；
- 电感值验证：实际应用前需用LCR测试仪确认电感值在3.76uH~5.64uH范围内，确保电路性能；
- 散热设计：连续工作在1.6A时，需在焊盘附近增加铜箔面积（建议≥5mm²），降低热阻；
- 封装匹配：确认PCB焊盘尺寸为1.6mm×2.0mm（适配2016封装标准），避免焊接不良。
六、品牌与可靠性说明
长江微电（cjiang）是国内磁性元件领域的成熟厂商，该产品符合RoHS 2.0环保标准，无铅焊接兼容；经批量测试验证，其电气参数一致性好，在-40℃~+85℃工作温度范围内性能稳定，适合工业级以下的常规应用场景。
总结：FTC201608S4R7MBCA以小体积、中等电流、低损耗为核心优势，是便携式设备、小型电源模块等场景的高性价比功率电感选择，可满足多数低压DC-DC电路的储能与滤波需求。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
