CD45-E2GA222M-VKA 产品概述

一、产品简介

CD45-E2GA222M-VKA 是 TDK 推出的安规抑制电容(X1/Y1 型),容量 2.2nF,容差 ±20%,适用于交流工况下的干扰抑制与浪涌吸收。该器件为插件封装(引脚距 P = 10mm),工作温度范围 -25℃~+105℃,额定交流工作电压可用于 400V / 440V 工况,设计用于直接并联到电网线路或线路对地,用以抑制电源干扰、提高 EMC 性能并保证人员与设备安全。

二、主要参数

  • 品牌:TDK
  • 型号:CD45-E2GA222M-VKA
  • 容值:2.2 nF
  • 容差:±20%
  • 工作温度:-25℃ ~ +105℃
  • 额定交流电压:400V / 440V(用于交流抑制场合)
  • 安规等级:X1、Y1(可作为跨线与线对地抑制电容)
  • 封装:插件型(插脚间距 P = 10 mm)

三、产品特性

  • 安规设计:符合安规抑制电容的设计要求(X1/Y1 分类),适合直接与市电连接,兼顾绝缘与抗脉冲能力。
  • 温度与电压耐受:-25℃ 到 +105℃ 的宽温区间和 400/440VAC 的交流工况适应性,适合家电、工业及商用电源环境。
  • 插件结构:插件型封装便于波峰/手工焊接和维修,机械强度高、抗振动性能良好。引脚间距 10mm,便于在常见通孔 PCB 布局中使用。
  • 干扰抑制效果好:2.2nF 容值对削弱高频干扰和抑制电网瞬变有显著效果,同时容差 ±20% 在典型 EMI 抑制应用中属常见选择。

四、典型应用领域

  • 开关电源输入端的 EMI 抑制网络(共模/差模配合使用)。
  • 照明驱动、电子镇流器与 LED 驱动电源的线路滤波。
  • 家用电器与工业设备的电网干扰抑制与浪涌保护前端。
  • 仪器仪表和医疗、安防等需要安全隔离与抗干扰的电源前端(按相应安全规范选型并校核)。

五、安装与使用注意事项

  • 仅用于规定的安规用途:X1/Y1 分类电容用于抑制电源干扰,不应用作电气隔离替代。安装时应遵循电网与安全规范的爬电距离、气隙要求。
  • 焊接工艺:插件封装适合波峰或手工焊接,建议按制造商给出的焊接温度与时间曲线操作,避免长期超温影响绝缘与寿命。
  • 机械应力与固定:在装配和振动工况下,注意避免对引脚施加过大力矩或弯折,必要时采用固定胶或支撑结构减少应力。
  • 替换与选型:替换时确保容量、耐压、安规等级与封装一致,尤其是 X/Y 分类与工作电压必须满足原设计要求。

六、法规合规与质量保障

本系列为安规抑制电容,设计与制造遵循安规元件的要求,适用于需要通过 EMI 认证与电气安全审核的方案。具体认证(如 IEC/EN 安规、UL 列表等)及环境、可靠性试验结果请以 TDK 官方数据表和认证证书为准。采购与设计时建议参考最新的规格书,以确保满足目标市场的法规与认证要求。

结论:CD45-E2GA222M-VKA 以其 2.2nF 的抑制容量、X1/Y1 的安规等级和稳健的插件结构,适合用于对电源端干扰有严格要求的商用与工业应用。选型时请核对工作电压、环境温度及安装条件,并遵照制造商的焊接与安装指引。

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
