FACT4532-510-2P-T 产品概述

一、产品简介

FACT4532-510-2P-T 是长江微电(cjiang)推出的一款 SMD 共模滤波器(双通道 / 4 引脚),封装尺寸 4.5 × 3.2 mm。该器件在 100 kHz 时测得电感约 51 μH,额定电流 200 mA,额定电压 50 V,直流电阻(DCR)约 1 Ω,工作温度范围 -40 ℃ 至 +125 ℃,绝缘电阻 ≥ 10 MΩ。器件在高频(10 MHz)具有显著阻抗(差模约 1 kΩ,共模约 2.8 kΩ),适合抑制中高频干扰,改善电磁兼容性能。

二、主要特性

  • 双通道结构(4 引脚),适用于两线差分或两路电源/信号线的共模干扰抑制。
  • 高共模阻抗:在 10 MHz 处共模阻抗可达约 2.8 kΩ(差模约 1 kΩ),对中高频干扰抑制效果好。
  • 中等电感量:51 μH(@100 kHz),利于低频至中频范围的噪声滤除。
  • 小型封装:4.5 × 3.2 mm SMD,便于高密度 PCB 布局与自动化贴装。
  • 宽温特性:-40 ℃ ~ +125 ℃,适应多种工作环境。
  • 良好绝缘性能:绝缘电阻 ≥ 10 MΩ,适合需要隔离与可靠性的场合。

三、典型应用场景

  • 消费类电子:机顶盒、机顶电视、机载/车载影音接口中对 EMI 的抑制。
  • 数据接口:USB、HDMI、LVDS 等差分信号链路的共模干扰过滤。
  • 通信与物联网终端:减少射频与开关噪声对敏感收发器的影响。
  • 电源滤波:小功率电源线的共模噪声抑制与整机 EMI 优化。
    (注意:额定电流 200 mA,适用于小电流场合,不建议直接用于大电流电源传输)

四、设计与使用建议

  • 放置位置:优先靠近干扰源或接口处封装,例如靠近连接器或开关元件,以截断噪声传播路径。
  • 布局注意:保持差分线对称、长度一致,避免在器件两侧形成回路开口;尽量在器件一侧使用连续地平面以增强共模路径。
  • 与旁路电容配合:常与高频旁路电容并用构成 LC 或 π 型滤波网络,以扩大滤波带宽与深度。旁路电容应靠近器件引脚焊盘布置。
  • 电流与温升:额定电流 200 mA,实际使用时考虑额定值余量及环境温度对电阻和温升的影响,必要时验证温升与饱和特性。
  • 焊接工艺:推荐采用标准回流焊工艺,遵循厂方回流曲线,避免超温或长时间高温影响磁性材料与绝缘性能。

五、可靠性与测试要点

  • 温度循环与高温储存下器件应保持电感与绝缘稳定;工作温度上限 +125 ℃ 提示可在工业级场景使用。
  • 绝缘电阻测试(≥10 MΩ)与 DCR(约 1 Ω)为常规检验项目;在最终应用中应验证在温漂与电流下的 DCR 变化与感值衰减情况。
  • 高频阻抗(10 MHz)为关键指标,应结合具体系统噪声频谱选择器件以达到最优滤波效果。

六、封装与订购信息

  • 封装形式:SMD-4P,尺寸 4.5 × 3.2 mm,适配自动贴装和回流焊。
  • 型号:FACT4532-510-2P-T(请在采购或设计前向供应商确认完整的技术规格书与最新版封装尺寸图以便 Footprint / 裁切与测试)。

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
