PCAQ4520MB-900 产品概述 — 谱罗德(PROD)

一、产品简介

PCAQ4520MB-900 是谱罗德(PROD)推出的一款表面贴装双通道共模滤波器(Common-mode choke),专为高速信号线与电源线的电磁干扰(EMI)抑制设计。器件封装为 SMD,外形尺寸为 4.75 × 4.5 × 2.0 mm,额定电压 50 V,额定电流 3.2 A,可在宽温度范围内稳定工作,适合消费类与工业类电子设备的 EMI 抑制需求。

二、主要电气参数

  • 通道数:2(双通道,共模滤波用途)
  • 额定电流:3.2 A(连续通过时的最大建议值)
  • 阻抗:90 Ω @ 100 MHz(共模阻抗,适用于中高频段 EMI 抑制)
  • 额定电压(DC/AC):50 V
  • 耐电压:50 V
  • 直流电阻(DCR):35 mΩ(低 DCR,有利于降低通流损耗和发热)
  • 工作温度:-25 ℃ ~ +125 ℃
  • 绝缘电阻:10 MΩ

三、产品特点

  • 高共模阻抗:在 100 MHz 附近表现出 90 Ω 的共模阻抗,能有效抑制高速信号或开关电源产生的共模干扰。
  • 低直流电阻:35 mΩ 的低 DCR 使其在大电流传输时损耗小,发热低。
  • 体积小巧:4.75 × 4.5 × 2.0 mm 的紧凑封装利于高密度 PCB 布局。
  • 宽温区与可靠性:支持 -25 ℃ 至 +125 ℃ 工作温度,并具备 10 MΩ 绝缘电阻,满足一般工业与消费电子可靠性要求。

四、典型应用

  • USB、HDMI、LVDS 等高速通信接口的共模噪声抑制
  • 各类开关电源(SMPS)输入/输出端的 EMI 滤波
  • 摄像头、显示器、网络设备等信号线的干扰抑制
  • 工业控制设备和消费类电子的电磁兼容(EMC)设计

五、PCB 布局与设计建议

  • 尽量将滤波器靠近干扰源或连接器放置,以缩短干扰回路的走线长度。
  • 差分或对称信号应通过器件的两通道,保持走线长度和阻抗一致,避免引入差模干扰。
  • 对于大电流应用,建议增大焊盘铜厚并采用适当过孔散热以降低温升。
  • 避免在滤波器两端放置不必要的大并联电容,可能影响滤波器的工作频段和抑制效果。

六、使用与可靠性注意事项

  • 不要超过额定电流 3.2 A 与额定电压 50 V;长时间超额工作会导致器件发热或损坏。
  • 焊接时遵循推荐的回流焊温度曲线,避免超温或长时间高温导致磁芯特性退化或结构损伤。
  • 存储与使用环境应避免强酸强碱及潮湿环境,必要时采取防潮措施。
  • 在高振动或冲击环境中使用前,建议进行可靠性验证以确认机械稳定性。

七、选型建议

PCAQ4520MB-900 适合需要在中高频段(约 100 MHz)抑制共模干扰且对电流损耗有较高要求的场合。若工作温度需覆盖更低温(如汽车级 -40 ℃)或需更高耐压/更高电流,应参考厂商其它系列或联系谱罗德获取详细性能曲线与样品测试数据以验证适配性。

如需进一步资料(阻抗曲线、典型损耗、焊接规范、推荐封装过孔与 PCB 尺寸等),建议向供应商获取完整数据手册(Datasheet)与应用指南。

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
