PSCLAQ0905-472Y 产品概述
一、产品简介
PSCLAQ0905-472Y 为谱罗德（PROD）出品的一款表面贴装式共模滤波器（共模电感）。器件尺寸为9.2 × 6 × 5 mm，双通道设计，面向对开关噪声和电磁干扰（EMI）有较高抑制要求的电源与信号链路。主要电气参数为 4.7 mH（@100 kHz）、额定电流 400 mA、100 kHz 时共模阻抗约 4 kΩ，直流电阻（DCR）约 900 mΩ，额定耐压 80 V，工作温度范围 -25℃～+105℃。
二、主要性能特点
- 高共模阻抗：在 100 kHz 时达到约 4 kΩ，适合抑制开关电源及电机驱动中的低中频干扰。
- 适中电感量：4.7 mH（@100 kHz），对较低频段噪声有良好抑制效果。
- 额定电流与DCR：额定电流 400 mA，直流电阻约 0.9 Ω，兼顾泄漏与功率损耗。
- 紧凑封装：SMD 带来自动贴装、可靠焊接的生产便利，尺寸 9.2×6×5 mm 适用于空间受限的功率模块或接口板。
- 宽工作温度：-25℃ 至 +105℃，适合工业级或车规周边环境的应用（请参照系统热设计进行适配）。
三、典型应用场景
- 开关电源输入滤波（SMPS 入端共模抑制）
- DC-DC 转换器与一级滤波网络
- 电机驱动和伺服控制器的 EMI 抑制
- 电源线或数据线（需兼顾共模）滤波，如工业以太网、CAN 总线周边（前端滤波）
- 各类便携设备与通信设备的 EMI 任意降噪设计
四、封装与安装注意事项
- 封装形式：SMD，外形尺寸 9.2×6×5 mm，推荐采用回流焊工艺贴装。
- 焊接建议：遵循回流曲线，避免过高峰值温度与超时停留以防磁芯或绕组损伤。
- PCB 布局：共模滤波器两端应尽量紧靠待滤噪声源与地的去耦电容，减少环路面积；输入与输出走线分离，避免将敏感信号与滤波地混合。
- 热管理：器件 DCR 导致一定发热，长期高电流工作时需评估环境温升并留有散热裕度。
五、使用建议与注意事项
- 电流裕量：在设计中建议对额定电流 400 mA 做适当裕量设计，避免长期接近或超过额定值引起磁芯饱和与发热。
- 电压与绝缘：额定耐压 80 V，请勿在高于该值的系统中直接使用或将其作为一次侧绝缘屏障。
- 频率特性：给出的电感量与阻抗基于 100 kHz 测试点，实际应用中随频率变化，请结合目标频谱选择匹配滤波拓扑。
- 测试与验证：在系统样机阶段，应测量实际 EMI 抑制效果并评估与其他滤波元件（如差模电感、X/Y 电容）的配合效果。
六、结语
PSCLAQ0905-472Y 以其较高的共模阻抗、适中的电流处理能力及紧凑 SMD 封装，适用于需要在中低频段抑制共模噪声的电源与驱动类电路。实际选择时请结合系统电流、频谱特性与温升限制进行评估，以确保长周期稳定运行。若需进一步的频率响应曲线、回流焊工艺参数或样片测试数据，可向供应商索取详细资料。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
