FTC160808S1R0MBCA 产品概述

一、产品简介

FTC160808S1R0MBCA 是长江微电(cjiang)推出的一款表面贴装功率电感,封装尺寸为 0.8×1.6 mm(1608 型)。器件标称电感值 1 μH,公差 ±20%,面向对体积、成本与电流能力有综合要求的便携与工业类电源应用。该系列器件具有较低直流电阻(DCR)、良好的额定电流能力以及较高的饱和电流特性,适合用于低功率 DC-DC 变换器与电源滤波电路。

主要规格一览:

  • 品牌:cjiang(长江微电)
  • 型号:FTC160808S1R0MBCA
  • 电感值:1 μH ±20%
  • 额定电流(Isat之前的连续电流):2.1 A
  • 饱和电流 Isat:3 A(常见定义为在该电流下电感值下降到标称值的某一比例)
  • 直流电阻 DCR:约 180 mΩ
  • 封装:SMD,尺寸 0.8 × 1.6 mm(1608)

二、关键特性与优势

  • 小尺寸高集成:1608 小型封装能有效节省 PCB 面积,适合空间受限的移动设备与便携式电源模块。
  • 良好的电流承载能力:额定电流 2.1 A,可满足小功率同步降压/升压转换器与负载供电需求;饱和电流 3 A,能在瞬态或过载情况下保持较好的电感特性。
  • 低 DCR:约 180 mΩ 的直流电阻可降低铜损,提高系统效率,尤其在中低电压、大电流场合更为明显。
  • SMD 工艺兼容:适用于自动化贴装与无铅回流焊工艺,便于批量生产与可靠装配。

三、典型应用场景

  • 移动终端与可穿戴设备的电源滤波与储能
  • 便携式电源 / 电池管理模块(降压/升压转换器)
  • IoT 节点、蓝牙模块等对体积和功耗敏感的无线设备
  • LED 驱动电源与小功率工业控制电源
  • EMI 滤波与输入输出端 LC 滤波器

四、性能注意事项与使用建议

  • 电流与温升:额定电流 2.1 A 指在限定温升条件下的连续使用能力;实际使用中要考虑 PCB 散热、环境温度和邻近元件的发热。建议对高电流路径做铜皮加厚或增加散热面,必要时进行热仿真评估。
  • 饱和电流定义:若需精确评估 Isat 的影响,请参考厂方具体定义(通常为电感下降到标称值的 30% 或 20% 时的电流)。在大电流脉冲或启动瞬态中,注意电感值下降对环路性能的影响。
  • DCR 与效率:180 mΩ 的 DCR 在某些高电流应用会引起显著损耗,应在效率预算中考虑这部分功耗(P = I^2·DCR)。
  • 频率特性:作为功率电感,适用于从几十 kHz 到几 MHz 的开关频率范围。高频下的有效电感值与损耗会受磁芯材料与绕组寄生参数影响,设计时可结合仿真与实测曲线调整元件选型。
  • 焊接与可靠性:兼容无铅回流焊(建议遵循 IPC/JEDEC 回流曲线,峰值约 260 ℃),避免重复多次高温回流。存储和潮湿敏感性按制造商建议处理,未拆封前妥善防潮。

五、PCB 布局与封装建议

  • 放置位置:尽量靠近电源转换器芯片的相关电路,缩短电感与开关管、肖特基二极管或电容之间的回路长度,以降低寄生电感与 EMI。
  • 焊盘设计:为保证焊锡充分润湿并提升机械强度,推荐按照厂方推荐焊盘尺寸设计,并保证良好焊锡量。若板上电流较大,可在焊盘下方或周围增加铜厚或热散铜面。
  • 去耦电容布局:输入输出电容尽可能靠近电感与开关元件布局,以减少回路面积,改善稳定性与 EMI 性能。

六、采购与可靠性

  • 订购信息:型号 FTC160808S1R0MBCA,品牌 cjiang(长江微电),建议向授权经销商或厂方渠道订购以保证质量与批次一致性。
  • 质量与测试:建议在设计验证阶段对器件进行实际电气/热特性测试(如感值随电流曲线、DCR 随温度变化、饱和特性)以确认在目标工况下的表现。
  • 存储建议:遵循元器件湿敏等级(MSL)和厂方包装说明,避免潮湿环境导致焊接缺陷。

总结:FTC160808S1R0MBCA 是一款面向小型化电源设计的功率电感,结合 0.8×1.6 mm 的微型封装与超过 2 A 的稳态电流能力,适合移动、物联网及小功率开关电源场景。设计时需综合考虑电流、温升与电路布局,以发挥其在效率与体积方面的优势。若需进一步电气曲线(频率响应、感值随电流变化曲线、温度系数等),建议索取厂方详细数据手册。

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.
