FTC303020D100MBCA 产品概述

一、产品简介

FTC303020D100MBCA 是长江微电(cjiang)一款表面贴装功率电感,标称电感值 10 μH,公差 ±20%,封装尺寸为 SMD 3×3 mm,适用于小型化开关电源和电源滤波场景。该器件额定电流 2.5 A,饱和电流(Isat)3.8 A,直流电阻(DCR)135 mΩ,设计以承受中等电流密度并兼顾体积与成本。

二、主要参数与解读

  • 电感值:10 μH ±20%(一般在规定测试条件下测量,实际电路中受到直流偏磁和频率影响会下降)
  • 额定电流:2.5 A(连续工作时建议按额定或适当降额使用以控制温升)
  • 饱和电流(Isat):3.8 A(用于判断在短时或峰值电流下磁芯是否进入饱和)
  • 直流电阻:135 mΩ(影响导通损耗与效率,需在热设计中考虑)
  • 封装:SMD,3×3 mm,便于高密度 PCB 设计与自动化贴装

三、应用场景

适合用于:

  • 降压(buck)/ 升压(boost)等开关稳压器的电感元件
  • 电源输入/输出滤波,抑制开关噪声与纹波
  • 电池供电设备、电源管理模块、小型化功率模块

四、选型与设计建议

  1. 电流与温升:直流损耗 P = I^2·DCR。举例在额定电流 2.5 A 时,P ≈ 0.135×2.5^2 ≈ 0.84 W,热量较大,应评估系统散热能力;若要求低温升,建议连续工作电流按 70%–80% 额定值降额(约 1.8–2.0 A)。
  2. 饱和裕量:峰值电流应明显低于 Isat(3.8 A),以保证电感不会进入饱和造成电路性能异常。
  3. 直流偏磁与有效电感:实际工作中 DC 偏磁会降低电感值,设计时应留出裕度或在样机上测量实际电感。
  4. 布局与焊接:走线尽量短且粗,靠近电感的电流回路应成闭环;为控制热阻,可在地铜或电源铜上使用过孔散热;遵循制造商推荐的焊盘尺寸与回流曲线。

五、可靠性与测试要点

  • 建议在目标温度与频率条件下测量电感和损耗,验证纹波电流和温升;
  • 关注高温下电感稳定性与机械抗振动能力;
  • 在自动贴装和回流焊后验证焊点完整性与电气参数变化。

六、选型总结

FTC303020D100MBCA 适用于追求体积小、成本适中并需要中等电流能力的功率电感应用场景。在应用中需特别注意较高的 DCR 带来的功耗与温升问题,合理降额与良好散热是保证长期稳定工作的关键。选型前建议获取完整数据手册并结合实际电路测试最终确认。

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
