PSCLAQ0905-471Y 产品概述

一、产品简介

PSCLAQ0905-471Y 是谱罗德(PROD)推出的一款 SMD 共模滤波器,针对需要在有限空间内实现对差模/共模干扰抑制的场合设计。核心参数包括共模电感 470 µH(@100 kHz)、共模阻抗约 1 kΩ(@100 kHz)、额定电流 1.1 A,器件尺寸为 SMD-4P,外形尺寸 9.2 × 6 mm。该器件工作温度范围 -25 ℃ ~ +105 ℃,额定电压/耐压均为 80 V,直流电阻(DCR)典型值约 140 mΩ。适合中低压电子电源、信号线及噪声敏感电路的 EMI 抑制和共模滤波场景。

二、主要性能亮点

  • 共模电感 470 µH(@100 kHz):对高频共模噪声具备较强抑制能力,适用于 100 kHz 附近及更高频段的滤波需求。
  • 阻抗 1 kΩ(@100 kHz):提供良好的阻抗匹配与噪声衰减效果,适用开关电源、DC-DC 转换器等产生的高频干扰。
  • 额定电流 1.1 A:满足中小功率电路的连续工作电流需求,同时兼顾滤波性能与功耗。
  • 紧凑封装 SMD-4P(9.2 × 6 mm):适合表贴装配,节省 PCB 布局空间,便于自动化贴装与回流焊工艺。
  • 宽工作温度范围:-25 ℃ ~ +105 ℃,适应一般工业及消费类环境温度要求。

三、典型应用场景

  • 开关电源(SMPS)输入/输出滤波:抑制开关转换产生的共模噪声,降低对后端电路和电网的干扰。
  • DC-DC 转换器:在低压直流系统中作为 EMI 抑制器件,配合差模电容提升滤波效果。
  • 通信与控制信号供电线:对噪声敏感的信号线及接口处进行共模抑制,改善信号完整性。
  • 工业控制与电源模块:适用于额定电压在 80 V 以内的中低压应用场合。

四、电器参数说明(要点)

  • 直流电阻(DCR):约 140 mΩ(典型值),低 DCR 有利于降低功耗与发热。
  • 共模阻抗:约 1 kΩ(@100 kHz),表示在该频率下对共模干扰的阻抗能力。
  • 共模电感:470 µH(@100 kHz),用于评估滤波深度与截止特性。
  • 额定电流:1.1 A(连续),使用时应考虑峰值电流与温升。
  • 额定/耐电压:80 V,器件两端及对地电压应低于此值以保证安全。
  • 工作温度:-25 ℃ ~ +105 ℃,长期工作时请考虑温度对电感、DCR 的影响。

五、布局与安装建议

  • 推荐采用厂家提供的 PCB 封装尺寸与焊盘布局,以保证焊接强度和电气可靠性。
  • 在电源输入端或噪声源附近靠近布置共模滤波器,可最大化抑制效果。
  • 与差模电容、Y 电容或接地屏蔽联合使用可进一步提升整体 EMI 性能。
  • 回流焊装配时遵循常规 SMT 工艺规范及器件供应商给出的温度曲线,避免机械应力与过高回流峰值温度导致的损伤。
  • 考虑器件自身发热与周围热源,留出适当散热空间,必要时在 PCB 上使用铜厚或散热槽以降低温升。

六、选型与使用注意事项

  • 确认最大工作电压不超过 80 V;若应用存在更高瞬态电压,应增加抑制元件或使用更高耐压器件。
  • 对于存在较大差模电流或高峰值脉冲电流的应用,需核对器件的允许峰值电流与磁芯饱和特性,必要时选择更高额定电流或并联方案。
  • 注意环境温度、通风条件对额定电流能力的影响,必要时进行适当的热设计与降额使用。
  • 若关心更低 DCR 或更高频段阻抗特性,可与谱罗德技术支持沟通获取更详细的频率响应曲线与样品测试数据。

七、产品包装与支持

  • 封装形式:SMD-4P,外形尺寸 9.2 × 6 mm,适合自动化贴装。
  • 品牌:PROD(谱罗德),提供量产供货与技术支持。
  • 如需样品、频响曲线、回流焊温度规范或 3D 封装数据,请联系供应商或代理商获取完整资料以便于设计验证与可靠性评估。

以上为 PSCLAQ0905-471Y 共模滤波器的主要概述与实用建议。根据具体电路与 EMI 要求,可在此基础上进行原理验证与 PCB 调整,以达到最佳滤波与系统可靠性。

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
