电弧在电路中的产生会引发众多问题，导致操作的不稳定性。如果缺乏有效的灭弧措施，电弧会导致继电器、开关触点以及固态元件（例如SCRs和TRIACs）的早期损坏故障。

楼氏电容旗下的康奈尔品牌推出了QAS系列的RC型电弧抑制器/缓冲器组件。该系列通过在双引线径向封装中集成单个器件的RC网络，有效应对电弧问题。这些精心设计的网络能够显著延长电子设备的使用寿命，主要通过大幅减少甚至消除电接触点产生的电弧来实现。此外，QAS系列设备在抑制由火花引发的电磁干扰（EMI）和射频干扰（RFI）方面也表现出色，因为火花往往是噪音和干扰的主要来源。

QAS系列中的每个元件均由金属化聚酯电容器RC网络组成，表面涂有阻燃环氧树脂。相较于使用分立网络进行设计，采用集成RC网络的单一元件设计，能够实现更紧凑且稳定的输出性能。

重点系列规格：

24台设备
电容值高达1.0μF
电阻值高达680欧姆
额定电压选项高达1600 伏直流/660伏交流，60赫兹
在满额定电压下，工作温度范围为-55°C至+85°C

消弧/缓冲网络设备的工作原理

在直流（DC）电压的应用中，RC网络通常连接在继电器触点上；而在交流（AC）电压的应用场景下，RC网络则连接在负载之上。

当消弧电路中的触点断开时，电压会被施加到电容器上，而非直接作用于继电器触点上。由于电容器充电的过程极为迅速，远短于触点断开所需的时间，因此能够有效避免电弧的产生。

当触点闭合时，来自充电电容器和电源的电流可能会超过触点安全电导的极限承受范围。在这种情况下，网络中的电阻器起到了至关重要的作用，它能有效地限制浪涌电流，减少电弧的产生，进而延长触点的使用寿命。

Combat Electrical Arcing in Circuits with Suppressor/Snubber Network Devices for Relays

Knowles’ Cornell Dubilier brand offers a series of RC-type arc suppressor/snubber components, the QAS series, that combats arcing by providing single-device RC networks in two-lead radial packages. These networks can extend the operating life of electronic devices by dramatically reducing or eliminating arcing at the point of electrical contact. QAS series devices are also effective at reducing spark-generated EMI/RFI that can cause noise and interference.
