CS45-E2GA222M-NKA 产品概述

一、产品简介

CS45-E2GA222M-NKA 为 TDK 系列的安规电容(Safety Capacitor),型号对应容值 2.2nF、容差 ±20%,封装为插件式(引脚间距 P = 7.5mm)。该型号可用于符合 X 与 Y 类防护需求的电源滤波与干扰抑制场合,额定交流工作电压信息(用户提供)为 300V / 440V。适用于需要满足安规要求的 EMI 抑制、跨线和对地耦合场景。具体认证与详细电气参数请以厂方出具的规格书为准。

二、主要特性

  • 容值:2.2 nF(标称)
  • 容差:±20%
  • 安规等级:X1 / Y2(用于抑制电源线间及线对地干扰)
  • 工作电压(交流,用户信息):300V 或 440V
  • 封装形式:插件(直插,P = 7.5 mm)
  • 应用方向:交流电源 EMI 滤波、浪涌抑制、跨线/线对地耦合
  • 非极性元件,便于在交流电路中直接使用

三、安规等级与应用意义

  • X 类(跨线电容):用于连接交流电源相线与零线之间,承受电源瞬态脉冲与共模/差模干扰。X1 表示适用于更高能量的脉冲环境(相比 X2、X3),在设计时可用于较高电网干扰或长寿命要求的场合。
  • Y 类(对地电容):用于连接电源一端(相或零线)与机壳/地之间。Y2 为对地电容中的一个等级,强调在失效时不能对人体造成危险,通常需满足更严格的绝缘与泄漏电流限制。
  • 在实际电路中,可根据抑制目标选择将该型号作为跨线(X)或线对地(Y)元件,但必须严格遵循安规布局与认证要求,且不同封装/子型号的认证状态需以产品规格书为准。

四、典型应用场景

  • 家用电器和白色家电的开关电源输入滤波
  • 工业电源、变频器与控制器的电磁干扰抑制
  • LED 驱动电源、充电设备的跨线噪声滤除
  • 医疗、测量类设备周边 EMI 降噪(在满足对应 Y 级认证前提下)
  • 通用电源模块的共模/差模滤波网络

五、设计与选型建议

  • 按安规要求选型:尽量依照系统必须的安规类别(X1/X2/Y1/Y2)选用具有相应认证的元件,并保留制造商的认证文件以备审查。
  • 耐压与浪涌考虑:电容需有足够的耐冲击和耐振荡能力。如果工作环境存在高脉冲或雷击风险,应选能承受更高峰值电压或带有更高脉冲能量等级的器件。
  • 漏电流控制:Y 类电容会影响系统的漏电流总和,设计时需确保整机漏电流在安全标准范围内(特别是直接连接到人可触及部分的设备)。
  • 温度与老化:注意工作温度范围与温漂对容量的影响,必要时考虑在电路中增加去耦或补偿措施。
  • 并联/串联:为达到特定容值或电压等级,可采用并联/串联设计,但要注意均压与失配问题,并优先使用经过安规认证的组合方案。

六、安装与可靠性注意事项

  • 安装方式:该型号为插件式,适合波峰或手工焊接;在焊接时应遵循制造商推荐的焊接温度与时间,以避免损伤内部结构。
  • 引脚机械强度:在弯脚或插装过程中避免对引脚施加过大机械应力,防止内部连接受损。
  • 避免直流偏置下大幅降低容量:在某些薄膜电容类型中,直流偏置会影响有效容值。
  • 维修与更换:更换时请使用完全相同规格与相同安规级别的元件,不能用普通非安规电容替代。

七、可靠性失效与检测

  • 常见失效模式包括绝缘击穿(导致短路)、容值变化或漏电流增大。设计中应考虑防短路熔断措施与过压保护。
  • 建议在量产与工程样机阶段进行温度循环、湿热测试以及高压绝缘与耐冲击测试(按照 IEC/EN 安规标准)以确认长期稳定性。

八、采购与技术资料

  • 品牌:TDK
  • 型号:CS45-E2GA222M-NKA
  • 若需完整的机械尺寸、材料说明、认证证书(如 IEC/EN、UL、VDE 等)以及详细电气性能曲线,请向 TDK 或其授权代理商索取官方规格书与安规报告,确保在目标应用中满足所有法规与安全要求。

总结:CS45-E2GA222M-NKA 为一款面向电源输入滤波与安规应用的插件式安全电容,适用于需要 X/Y 级安规保护的电磁干扰抑制场景。选用与布局时应严格遵循安规规范并参考厂方规格书以确保系统安全与合规。

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.
