FTC404012S5R6MBCA 产品概述

一、概述

FTC404012S5R6MBCA 是长江微电(cjiang)推出的一款小型化一体成型T‑CORE贴片电感,封装尺寸为SMD 4.1×4.1mm。该型号采用扁线工艺与一体成型结构,实现体积小、散热与电流能力相对优化的设计。标称电感值为 5.6 μH,公差 ±20%,额定电流 3.0 A,饱和电流(Isat)4.5 A,直流电阻(DCR)116 mΩ,适用于对体积要求严格且需中等电流通断的开关电源与滤波场合。

二、主要电气参数(关键值)

  • 电感值:5.6 μH(±20%)
  • 额定电流:3.0 A(连续额定)
  • 饱和电流:4.5 A(Isat,指在规定条件下电感下降至某一比例时的电流点)
  • 直流电阻:116 mΩ
  • 封装:SMD,4.1 × 4.1 mm
  • 结构特点:一体成型 T‑CORE,扁线工艺,小体积设计

三、性能与优势

  • 小型化体积:4.1×4.1 mm 的紧凑封装,便于高密度PCB布局与空间受限的模块化设计。
  • 扁线工艺:扁线增加铜截面积与散热面积,有利于降低温升并提高电流承载能力(相对线径较小的绕线方式)。
  • 一体成型 T‑CORE:结构稳定、机械强度高,适合贴片装配与自动化生产。
  • 较高饱和电流:4.5 A 的饱和点为瞬态过载或启动浪涌提供一定余量,能在短时高电流情况下维持较好性能。

四、设计与选型建议

  • 连续电流与热耗:以额定电流 3 A 连续工作时,仅考虑铜损 P = I^2·DCR,可近似估算为 3^2 × 0.116 Ω ≈ 1.04 W。此为导线直流损耗,不含磁芯损耗与散热效率影响,设计时需考虑热管理与散热路径。
  • 额定与余量:建议连续工作电流留有余量(常用 70–80% 额定电流,即约 2.1–2.4 A)以降低发热并延长器件寿命;在需要大电流短脉冲时,可利用更高的 Isat 余量,但要注意电感值线性下降与磁芯非线性。
  • 电感容差影响:±20% 的电感公差在精确调谐滤波或共振应用中需预留设计裕量,若系统对电感值敏感,建议选用公差更窄的型号或配合电路调整。

五、典型应用场景

  • 开关稳压器(同步/非同步降压、升压转换器)——用于储能与输出滤波
  • 电源输入/输出滤波——抑制开关噪声与射频干扰
  • 模块化电源、通信设备、工业控制与消费电子中对体积与电流有折中需求的场合

六、PCB布局与焊接注意事项

  • 尽量缩短电感与电源开关元件之间的回流路径,减少寄生电感与噪声耦合。
  • 为降低温升,周围应保留散热空间,必要时在下方或附近设计铜箔/散热层以助散热。
  • 采用稳健的焊膏印刷与回流焊工艺,遵循元件制造商的回流温度窗口(若无具体数据,请遵循通用无铅回流规范)。
  • 储存与搬运时避免强冲击或弯折,贴片元件在回流过程中的机械应力较敏感,一体成型结构虽稳固但也需避免过度应力。

七、选型与替代建议

在选择时,若系统对直流损耗敏感或需更高连续电流,可考虑 DCR 更低、额定电流更高的同类器件;若对电感精度要求高,可选择公差更严格的型号或配合并联/分拆电感方案。最终选型建议以完整的器件数据表为准,并结合实际温升测量与寿命验证。

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
