PCAQ4532B-121T300 产品概述

一、概述

PCAQ4532B-121T300 为谱罗德(PROD)推出的一款双通道共模滤波器(共模电感/共模扼流器),针对工商业与消费类电源、接口的电磁干扰(EMI)抑制而设计。器件采用 SMD-4P 封装,外形尺寸 4.5 × 3.2 mm,体积小、性能稳定,适合集成在空间受限的电路板上以实现对高频共模噪声的有效抑制。

二、主要参数

  • 通道数:2(双通道)
  • 额定电流:3 A(连续工作)
  • 共模阻抗:120 Ω @ 100 MHz
  • 额定电压(DC/AC):50 V
  • 直流电阻(DCR):70 mΩ(每绕组)
  • 工作温度范围:-25 ℃ ~ +105 ℃
  • 绝缘电阻:≥10 MΩ
  • 封装:SMD-4P,外形尺寸 4.5 × 3.2 mm
  • 品牌:PROD(谱罗德)
  • 型号:PCAQ4532B-121T300

三、产品特性

  • 小体积高阻抗:在 100 MHz 处提供 120 Ω 的共模阻抗,对高频共模噪声有良好抑制能力,适合开关电源、USB/HDMI 等高速接口的 EMI 控制。
  • 低 DCR、低压降:70 mΩ 的直流电阻保证在 3 A 工作电流下压降与发热较小,有利于功率路径应用。
  • 宽温度工作范围:-25 ℃ 至 +105 ℃,可满足多数工业与民用环境的可靠性需求。
  • 高绝缘性:绝缘电阻 ≥10 MΩ,确保通道间及对地的电气隔离性能。

四、典型应用

  • 开关电源输入/输出滤波(SMPS)
  • USB、HDMI、LAN 等高速差分接口的共模噪声抑制
  • 汽车电子辅助电路(非高温型)与工业控制设备(在其温度范围内使用)
  • 消费类电子产品的 EMI 符合设计

五、封装与机械特性

器件为 SMD-4P 表贴结构,封装尺寸 4.5 × 3.2 mm,便于自动贴装与回流焊接。引脚布局适配常见 PCB 布线规则,有利于靠近噪声源(如电源输入端或接口端)安装以获得最佳滤波效果。

六、使用与注意事项

  • 额定电流 3 A 为典型连续电流值,实际应用中应考虑环境温度、PCB 散热以及长期老化等因素进行适当的电流与温度降额。
  • DCR 70 mΩ 在 3 A 下约产生 0.21 V 压降和相应的功耗,设计时需考虑电压降与热量释放。
  • 工作电压请勿超过 50 V(DC/AC),并确保系统绝缘满足设计规范。绝缘电阻 ≥10 MΩ 能保证较好的通道间隔离,但高湿或污染环境需采取防护措施。
  • 推荐器件贴近噪声源或端口放置,并与接地良好的参考平面配合,减少共模噪声通过布线耦合。

七、可靠性与生产工艺建议

  • 焊接:建议采用无铅回流焊标准工艺,遵循供应商或行业的回流曲线规范,避免超过器件允许的最大热应力。
  • 测试:建议在最终产品中进行温升、耐压、绝缘电阻及 EMI 测试以验证实际滤波效果与可靠性。
  • 采购与支持:订购时请确认完整型号 PCAQ4532B-121T300 及批次信息,更多技术资料、样品与应用指导可联系 PROD(谱罗德)或其授权分销渠道获取完整数据手册。

该产品在需要在有限空间内实现可靠 EMI 抑制的场合具有较高的性价比,是对抗 100 MHz 附近共模干扰的有效选择。

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
