FTC160808SR47MBCA 产品概述

一、产品简介

FTC160808SR47MBCA 是长江微电(cjiang)推出的一款贴片功率电感,封装尺寸为 0.8 × 1.6 mm,标称电感值 470 nH,公差 ±20%。该器件针对移动设备、消费电子与电源模块中对体积、效率和抗饱和性能的要求而设计,兼顾较高额定电流与较低直流电阻,适用于开关电源滤波与储能场合。

二、主要参数

  • 品牌:cjiang(长江微电)
  • 型号:FTC160808SR47MBCA
  • 电感值:470 nH ±20%
  • 额定电流(Irated):2.6 A(持续不超过此值以避免过热)
  • 饱和电流(Isat):4.1 A(通常定义为电感下降到初始值的 75% 时对应的电流)
  • 直流电阻(DCR):典型 80 mΩ
  • 封装:SMD,尺寸 0.8 × 1.6 mm

三、产品特性与优势

  • 小型化封装:0.8 × 1.6 mm 的紧凑体积便于高密度 PCB 设计,节省空间;
  • 高饱和电流:Isat 可达 4.1 A,适合峰值电流较高的开关稳压器应用;
  • 较低 DCR:80 mΩ 的低直流电阻有利于降低导通损耗,提升效率;
  • 良好热性能:在合理散热条件下能够稳定工作,适配移动电源与消费类电子的功率管理要求。

四、典型应用场景

  • DC-DC 降压/升压转换器电感(升降压型开关电源)
  • 电源输入/输出滤波(EMI 滤波、去耦)
  • 耐冲击电源模块与便携设备(移动电话、平板、可穿戴设备)
  • 小功率电机驱动与点焊电源等需要短时大电流的场合

五、设计与使用建议

  • 测量条件:建议以常用 LCR 测试条件进行验证(例如 100 kHz、0.1 Vrms),并参考厂家 Datasheet 的测试标准;
  • 工作电流与散热:在超过额定电流时,器件会发热并造成效率下降,建议预留一定的电流余量并优化 PCB 铜箔面积以增强散热;
  • PCB 封装与走线:由于器件体积小,推荐按厂家提供的推荐焊盘尺寸设计焊盘并保证焊盘与电源回路有足够的铜厚以减少寄生电阻与热阻;必要时在焊盘下方增加过孔以导热;
  • 焊接工艺:兼容回流焊工艺,遵循无铅回流温度曲线,避免过高峰值温度或超长高温暴露时间;
  • 环境与可靠性:避免在高湿、高腐蚀气氛下长期使用;存储与安装时注意防静电与机械应力。

六、可靠性与测试

  • 饱和与热特性:建议在目标应用环境下进行电感随直流偏置电流的曲线测试,以及温升测试以评估长期工作安全裕度;
  • 机械强度:小型 SMD 器件对焊接应力与振动敏感,装配过程需控制回流曲线与剪切力;
  • 建议在样机阶段进行完整的电源稳定性、环路恢复与长期老化测试。

七、选型与替代建议

当需要类似规格但不同特性的备选器件时,可关注同类小型功率电感产品,比较要点包括电感值与公差、Isat 与额定电流、DCR、封装尺寸与温度特性。对于更高效率需求可优先选择更低 DCR 的型号;对于更高峰值电流环境可选 Isat 更高的器件。

八、总结

FTC160808SR47MBCA(470 nH,±20%,Irated 2.6 A,Isat 4.1 A,DCR ≈ 80 mΩ,0.8×1.6 mm SMD)是一款面向紧凑型电源与滤波应用的功率电感,兼顾体积、导通损耗与抗饱和性能。合理的 PCB 设计与热管理能确保其在移动设备与电源模块中发挥最佳表现。如需量产或关键应用,建议参照长江微电官方 Datasheet 并进行系统级可靠性验证。

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.

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
