FTW2012FE2R2KT 产品概述

一、产品简介

FTW2012FE2R2KT 是长江微电(cjiang)推出的一款贴片功率电感,封装规格为 0805(2012英寸制)。该器件标称电感值为 2.2μH,公差 ±10%,面向便携电源、降压转换器与电磁干扰抑制等对体积与效率有较高要求的电路,兼顾小型化与功率处理能力。

二、主要参数

  • 品牌:cjiang(长江微电)
  • 型号:FTW2012FE2R2KT
  • 电感值:2.2 μH ±10%
  • 额定电流(Irated):1.04 A
  • 饱和电流(Isat):740 mA
  • 直流电阻(DCR):220 mΩ
  • 封装:0805(2012)表面贴装

三、特点与优势

  1. 小型化封装:0805 体积适合主流移动设备与紧凑型电源模块,便于高密度布局。
  2. 较高的额定电流:1.04 A 的额定电流能力在同尺寸器件中表现良好,适合中低功率转换场景。
  3. 明确的饱和特性:Isat 为 740 mA,可在实际选型中清晰评估在峰值负载下的电感衰减情况,便于保证系统稳定性。
  4. 低 DCR:220 mΩ 的直流电阻有利于降低铜耗,提高转换效率,尤其在持续大电流时能减小发热。
  5. 稳定的电感容差:±10% 的容差在多数电源设计中属于可接受范围,便于设计与成本平衡。

四、典型应用场景

  • 开关电源(DC-DC 降压/升压转换器)
  • 移动电源与便携式设备电源管理模块
  • LED 驱动与背光电源
  • 电磁干扰(EMI)滤波与电源滤波网络
  • 车载电子与工业控制中小电流应用

五、封装与可靠性

FTW2012FE2R2KT 采用标准 0805 表面贴装制程,兼容标准回流焊工艺。产品设计兼顾温升与长期可靠性,适用于经常切换的开关电源环境。建议在 PCB 布局时留意散热路径与旁路电容布局,以降低整体热阻并优化性能稳定性。

六、选型与使用建议

  1. 峰值电流不要长期超过 Isat,否则电感值将明显下降,影响电源环路稳定。建议工作电流优先按额定电流(1.04 A)作为持续使用参考。
  2. 在考虑效率时,应将 DCR(220 mΩ)列入损耗计算,尤其在高占空比或大电流负载下。
  3. 若电路对电感容差敏感,可在设计中加入适配的电容或调整电感值以补偿 ±10% 的偏差。
  4. 推荐按照厂商提供的焊接曲线进行回流焊,避免超温或长时间高温以防性能退化。
  5. 如需在更严苛温度或更高电流场景使用,建议联系供应商获取更多热特性与电流-电感曲线以做详尽验证。

总体而言,FTW2012FE2R2KT 在 0805 小封装内实现了平衡的电流处理能力与较低 DCR,是面向中低功率开关电源与滤波场合的实用选择。若需样品、封装尺寸数据或更详细的电气特性曲线,可向长江微电索取完整规格书与测试报告。

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
