FTC201610D2R2MBCA 功率电感产品概述

FTC201610D2R2MBCA是长江微电(cjiang)推出的一款超小型贴片功率电感,专为低压直流-直流(DC-DC)转换、滤波等电路设计,核心优势在于高电流密度、紧凑封装,可满足便携电子、物联网设备等对空间利用率的严苛需求。

一、核心性能参数解析

该电感的关键参数直接定义了应用边界,具体解读如下:

  1. 电感值与精度:标称电感值2.2μH,精度±20%。电感值是储能、滤波的核心指标,2.2μH属于中小功率场景的常规值,±20%精度可覆盖大多数消费级设备的滤波需求,无需额外高精度校准。
  2. 电流承载能力:包含两个关键参数——
    • 额定电流(Irms)2.5A:指连续工作时不超过最高允许温度的最大电流,是日常稳定工作的参考阈值;
    • 饱和电流(Isat)3.3A:指电感值下降30%时的临界电流,代表抗过载能力,可应对开机浪涌、瞬间负载波动等场景。
  3. 直流电阻(DCR):125mΩ(毫欧)。DCR是线圈的直流电阻,直接影响功率损耗(P=I²·R),低阻值可减少电源转换效率损失,提升设备续航。
  4. 封装尺寸:SMD贴片封装,长宽1.6×2mm(无明确厚度信息,对应超小型贴片规格),体积紧凑,适配高密度PCB布局。

二、封装设计与工艺特点

该电感采用贴片式表面安装工艺,具备以下设计优势:

  1. 小型化适配:1.6×2mm的尺寸比传统0805封装小约50%,可显著减少PCB占用面积,尤其适合智能手表、蓝牙耳机等便携设备的内部空间优化。
  2. 自动化兼容:SMD封装支持回流焊、波峰焊等自动化贴装,生产效率高,适合大规模量产。
  3. 结构稳定性:采用长江微电主流绕线/一体成型工艺,线圈固定牢固,抗振动、抗冲击性能较好,可应对移动设备的日常跌落、振动场景。

三、典型应用场景

参数特性使其适配以下主流应用:

  1. 便携电子设备:智能手机、平板电脑、智能手表的DC-DC降压模块(将电池高压转为低电压给CPU、内存供电),利用小体积和高电流密度提升续航与空间利用率。
  2. 物联网终端:传感器节点、智能家居设备(智能灯泡、温湿度传感器)的电源滤波电路,过滤电源纹波,保证信号稳定。
  3. 小型家电与充电器:手机快充充电器、蓝牙耳机充电盒的电源转换电路,低DCR降低发热,提升充电效率。
  4. 低压汽车电子:车载USB接口、仪表盘小功率模块的电源电路(需确认工作温度是否覆盖汽车级需求)。

四、品牌与可靠性优势

作为长江微电产品,具备可靠质量保障:

  1. 品牌背书:长江微电是国内电感行业知名厂商,专注功率电感研发十余年,产品覆盖消费、汽车、工业领域,一致性与稳定性经市场验证。
  2. 参数一致性:量产产品的电感值、DCR、电流参数偏差控制在规格范围内,减少批量应用时的性能波动。
  3. 环境适应性:符合常规消费级工作温度范围(如-20℃~85℃),可应对日常温度变化,部分批次支持宽温(需确认具体型号)。

五、选型注意事项

实际应用需关注:

  • 工作电流需低于额定电流2.5A,避免长时间过载发热;
  • 若需应对高频纹波,需确认自谐振频率(SRF)是否匹配(通常该型号SRF为几MHz到几十MHz,适合常规DC-DC频率);
  • 封装尺寸需与PCB焊盘设计匹配,避免贴装偏移。

总结:FTC201610D2R2MBCA是一款高性价比超小型功率电感,兼顾小体积、高电流密度与低损耗,适合对空间敏感的便携电子、物联网等场景,是长江微电消费级电感市场的主力产品之一。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
