PROD谱罗德PCAQ2012B-900T040共模滤波器产品概述

一、产品定位与核心作用

PCAQ2012B-900T040是一款贴片式双路共模滤波器,核心作用是抑制电子电路中的共模干扰(即线路中同时存在于两根导线与地之间的干扰信号),帮助设备满足电磁兼容(EMC)标准,避免干扰影响自身或周边设备的正常工作。其设计针对低压小功率电路,兼顾小封装与高效滤波,适合高密度PCB布局场景。

二、基础电气参数详解

1. 核心滤波与功率参数

  • 通道数:2:双路并行设计,可同时处理差分信号对(如USB、CAN总线的正负线)或双路电源线路,简化电路设计,无需多颗单通道器件。
  • 额定电流:400mA:持续工作电流上限,满足多数低压小功率模块(如传感器、LED驱动)的电流需求;短路时可承受短时间过流(实际需结合电路保护)。
  • 阻抗:90Ω@100MHz:共模阻抗是滤波能力的核心指标——100MHz是数字电路(时钟、高速逻辑)、通信模块常见的干扰频率,90Ω阻抗可有效衰减该频段的共模干扰,提升电路抗扰性。

2. 电压与损耗参数

  • 额定电压:50V(交/直流通用):安全工作电压范围,覆盖多数消费电子、汽车低压电路(如12V/24V系统);耐电压50V与额定电压一致,确保电路过压时的基本绝缘安全。
  • 直流电阻(DCR):300mΩ:极低直流损耗,额定电流下功耗仅0.048W(公式:(P=I^2R=0.4^2×0.3)),发热极小,适合小封装长期稳定工作。

3. 绝缘与可靠性参数

  • 绝缘电阻:10MΩ:两根通道之间、通道与地之间的绝缘性能优异,可避免信号串扰或短路,提升电路可靠性。

三、封装与物理特性

采用0805贴片封装(尺寸约2.0mm×1.25mm×0.8mm),属于主流小型化封装:

  • 适配自动化贴装产线,生产效率高;
  • 尺寸紧凑,适合手机、可穿戴设备、汽车电子小模块等高密度PCB设计;
  • 表面贴装工艺稳定,焊接可靠性高,无引脚氧化问题。

四、工作环境适应性

  • 温度范围:-40℃~+125℃:宽温设计覆盖工业级/汽车级环境需求,可用于发动机舱附近(汽车电子)、户外工业传感器(低温/高温交替)、消费电子高温场景(如充电时的设备内部);
  • 无特殊环境要求(如防潮、防腐蚀),常规PCB防护即可满足多数应用。

五、典型应用场景

  1. 汽车电子:车载传感器模块(如胎压监测、温度传感器)、LED照明控制电路、小功率CAN总线接口;
  2. 消费电子:手机/平板的USB充电电路、音频接口(抑制电磁干扰)、WiFi/蓝牙模块信号滤波;
  3. 工业控制:小型PLC输入输出模块、现场传感器接口(如4-20mA信号线路);
  4. 通信设备:家用路由器、IoT网关的以太网接口、低功耗通信模块滤波。

六、品牌与可靠性保障

由PROD谱罗德(专业EMC器件品牌)出品,产品符合IEC 61000-4-2/3等电磁兼容标准,批量生产一致性好,参数偏差小;长期应用验证表明,其在宽温、低损耗场景下的可靠性稳定,适合量产需求。

综上,PCAQ2012B-900T040是一款小封装、低压小功率、宽温适用的双路共模滤波器,可高效解决多数电子设备的共模干扰问题,是高密度PCB设计的实用选择。

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.

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
