FTC201610S3R3MBCA 产品概述

一、产品简介

FTC201610S3R3MBCA 是长江微电(cjiang)系列的小封装功率电感,额定应用于紧凑型开关电源和电源滤波场景。器件尺寸仅 1.6 × 2.0 mm,标称电感值 3.3 μH,公差 ±20%,面向空间受限但需中等电流承载的移动设备、模块电源与功率管理电路。

二、主要参数

  • 电感值:3.3 μH(±20%)
  • 额定电流(Irated):1.7 A(持续工作建议值)
  • 饱和电流(Isat):2.3 A(出现明显电感下降的电流点)
  • 直流电阻(DCR):140 mΩ
  • 封装:SMD,尺寸 1.6 × 2.0 mm
  • 品牌:cjiang(长江微电)

三、核心特性

  • 小尺寸、高度集成,适合空间受限设计。
  • 额定电流 1.7 A,适用于小功率降压/升压转换器及端口供电。
  • 饱和电流相对较高(2.3 A),短时峰值电流允许一定裕量。
  • DCR 为 140 mΩ,电阻损耗不可忽视,需要在热设计中考虑功耗。

四、适用场景

  • 手机、平板等便携设备的电源模块(PMIC 输出滤波、负载开关滤波)。
  • 小功率 DC-DC 降压/升压转换器的储能元件。
  • EMI 滤波与电源去耦应用。
  • 工业与通信设备中对体积与成本有严格限制的电源子系统。

五、封装与安装要点

  • 器件为 SMD 贴片,建议按厂家推荐封装和焊盘布局设计 PCB,保证焊点可靠性与良好散热通道。
  • 回流焊时遵循厂方回流曲线,避免温度过高或过长的热暴露。
  • 布局时尽量缩短电感与开关器件、旁路电容之间的回流环路,降低 EMI 干扰与寄生损耗。

六、选型与热管理建议

  • 关注 DCR 带来的 I^2R 损耗:在额定电流 1.7 A 下,约为 P ≈ I^2·R = 1.7^2 × 0.14 ≈ 0.40 W(为近似值),应评估 PCB 散热及周围器件的温升容忍度。
  • 若系统中存在更高连续电流或长时间大电流脉冲,建议选择 DCR 更低或额定电流更高的型号以降低温升和效率损失。
  • 考虑到 ±20% 的电感公差,需在回路设计中评估最差和最好情况下的纹波电流、环路稳定性与磁饱和裕量。

七、可靠性与测试建议

  • 在样机验证阶段,测量实际工作条件下电感值、DCR 与温升(在实际 PCB 上通电测试),同时监测饱和特性在峰值电流下的表现。
  • 做振荡稳定性与输出纹波测试,确认与电容和开关器件配合不会引入不良共振。
  • 长期可靠性关注回流焊耐受、机械强度和在高温环境下的电气参数漂移。

八、注意事项

  • 避免长期工作在或接近饱和电流点,长期过载会导致电感值下降并加剧发热。
  • 设计时兼顾效率与体积,必要时在 PCB 设计中增加散热铜箔或热通孔以降低温升。
  • 如需更具体的回流曲线、频率特性测试数据或封装图纸,请向厂商索取详细数据手册以完成最终验证。

以上为 FTC201610S3R3MBCA 的产品概述与工程使用要点,适合在样机验证和量产前做为选型参考。若需将其与其它型号作对比或需要具体电路仿真参数,我可以继续提供帮助。

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
