PCAQ2012A-801T030 产品概述
一、产品简介
PCAQ2012A-801T030 是谱罗德（PROD）系列的一款小型表面贴装共模滤波器（Common‑Mode Choke），封装形式为 SMD‑4P，尺寸 2.0 × 1.2 mm，适用于对两线信号/差分对的共模干扰抑制。器件针对高频 EMI 抑制进行了优化，结构紧凑，便于在空间受限的移动设备和消费类电子中使用。
二、主要参数
- 型号：PCAQ2012A-801T030（PROD）
- 直流电阻 (DCR)：880 mΩ（每绕组典型值）
- 阻抗：800 Ω @ 100 MHz（共模）
- 额定电压：50 V（AC / DC 标称）
- 额定电流：250 mA
- 工作温度范围：-25 ℃ ～ +125 ℃
- 通道数：2（双通道，共模用）
- 封装：SMD‑4P，2 × 1.2 mm
三、主要特性与优势
- 高频共模阻抗 800 Ω@100 MHz，可有效抑制 100 MHz 附近的共模干扰与辐射。
- 小尺寸 SMD 封装，适合板上密集布局与便携设备。
- 耐温范围宽（-25～125℃），满足一般工业与民用环境可靠性要求。
- 直流电阻 0.88 Ω，250 mA 电流下压降约 0.22 V，功耗约 55 mW，热耗可控。
四、典型应用场景
- 消费类与移动设备的高速信号线 EMI 抑制（例如差分信号对、音视频线）。
- 通信接口与传感器线路的共模干扰控制。
- 小功率电源线或控制信号的共模滤波场合（注意额定电流限制）。
五、设计与使用建议
- 将器件尽量靠近干扰源或入板接口放置，以提高抑制效果（例如靠近连接器或接口处）。
- 注意 DCR 导致的电压降与发热，若运行电流接近 250 mA，应评估温升与长时间可靠性。
- 与旁路/差分电容合理配合，形成低通或带阻的 EMI 抑制网络；避免在差模路径上引入不必要的差模阻抗。
- 选择焊盘与回流工艺时，遵循厂商推荐的 PCB 封装图和回流温度曲线以保证可靠焊接。
六、封装与可靠性
- SMD‑4P 小封装便于自动贴装与波峰/回流焊工艺。
- 工作温度与电气规格适合一般商用与轻工业环境；长时间在高温、高电流工况下应用需做可靠性验证。
七、注意事项
- 额定电流 250 mA 对于电源线或高电流接口（如大电流 USB）不适宜，应选择更高电流等级的器件。
- 若系统对差模性能有严格要求，需结合实测的差模特性与串联电感情况评估整体影响。
PCAQ2012A-801T030 适用于小型化、对高频共模噪声有抑制需求且电流不大的场合，是常见的信号线 EMI 解决方案之一。若需更高电流或特殊频带的抑制性能，可联系供应商获取更详细的频率响应曲线与封装建议。

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.
