PSCIAQ3225-510Z 产品概述

一、产品简介

PSCIAQ3225-510Z 是 PROD(谱罗德)推出的一款小型表面贴装共模滤波器(Common‑Mode Choke),封装为 SMD‑4P,外形尺寸 3.2 × 2.5 mm,适用于对共模干扰进行抑制的空间受限电路。器件为双通道结构(4 引脚),面向汽车电子、通信、工业控制和消费类电子等需要抑制开关电源与高速信号线共模噪声的应用场景。

二、主要参数

  • 通道数:2(共模双通道,4 引脚)
  • 共模电感:51 µH @ 100 kHz
  • 额定电流:200 mA(直流)
  • 阻抗:2.6 kΩ @ 10 MHz
  • 额定电压 / 耐电压:80 V(DC / AC 标称)
  • 直流电阻(DCR):700 mΩ(每通道)
  • 工作温度范围:-25 ℃ ~ +105 ℃
  • 绝缘电阻:10 MΩ(测量条件请参考厂方资料)
  • 封装:SMD‑4P,尺寸 3.2 × 2.5 mm
  • 品牌:PROD(谱罗德)
  • 型号:PSCIAQ3225-510Z

三、性能特点

  • 高共模电感(51 µH@100 kHz),对低频共模噪声(开关转换、DC‑DC 打嗝等)抑制效果显著。
  • 在 10 MHz 时阻抗达 2.6 kΩ,可有效抑制射频段的共模干扰,覆盖常见 EMI 频段。
  • 小型 SMD 封装,适合高密度 PCB 布局与自动化贴装。
  • 额定电流 200 mA,适用于信号线和小电流供电路径。
  • DCR 700 mΩ,额定电流下压降与损耗较小(0.2 A × 0.7 Ω = 0.14 V,功耗约 28 mW),对低电压应用影响有限。
  • 宽温度范围,适应一般工业与消费类工作环境。

四、典型应用

  • 开关电源输入/输出的共模噪声抑制
  • USB、CAN、RS‑485 等差分/信号线的 EMI 滤波
  • 工业控制与传感器接口的干扰抑制
  • 车载电子中低电压信号线(需注意汽车级验证与更高的耐压/温度要求)

五、使用与选型建议

  • 若目标为高速差分信号的差模完整性(DIFF)要求较高,应评估共模滤波器对差模特性的影响;本件以共模抑制为主,差模插入损耗较小但仍需验证。
  • 对于大电流或较高温升场合,应预留裕量,避免长期满载工作;必要时选择更高额定电流型号或并联方案(并联需注意磁饱和与平衡问题)。
  • 耐压 80 V,若系统存在更高瞬态/浪涌,请加保护元件(TVS、限流等)或选用更高耐压器件。
  • 安装时尽量缩短信号线至滤波器的走线长度,并在滤波器侧做好接地过渡和旁路电容布局,以提高共模噪声环路的衰减效率。

六、封装与可靠性

  • SMD‑4P 小型封装适合回流焊工艺,建议按照厂方资料执行焊接温度曲线以保证可靠性。
  • 绝缘电阻 10 MΩ 表明器件在正常条件下具有良好的绝缘特性,但具体耐压/绝缘测试条件请参考供应商试验规程。
  • 工作温度覆盖 -25 ~ +105 ℃,满足多数工业/民用场景。长期高温工作下应关注电感退磁与 DCR 变化。

七、典型电路与布局建议

  • 将共模滤波器置于干扰源与敏感接收端之间,输入侧并联适当的去耦电容以构成更完整的 EMI 抑制网络。
  • 对高速差分线,保持滤波器两端差分走线对称,避免走线突变产生差模干扰。
  • 接地平面应完整,滤波器近地端应靠近系统地平面或返回路径,以缩短共模噪声环路面积。

结论:PSCIAQ3225-510Z 以其高共模电感、小型封装及良好高频阻抗,适合用于空间受限且需抑制中低频至射频共模干扰的信号/电源线路。实际选型与应用中请结合系统电流、耐压和热预算,并参阅厂方完整数据手册以获得焊接、机械和电气的详细规范。

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.
