CD45-E2GA472M-VKA 产品概述

一、产品简介

CD45-E2GA472M-VKA 是 TDK 推出的安规类插件电容器,额定容值 4.7nF(标称),公差 ±20%。本件标称用于交流电网抑制,防护等级为 X1、Y1,适用于工作电压 AC 400V / 440V 环境,工作温度范围 -25℃ ~ +105℃,标准插件引脚间距 P = 10mm。此类元件针对电源端的电磁干扰(EMI)和过渡脉冲抑制设计,便于在传统穿孔线路板上安装和更换。

二、主要特性

  • 容值:4.7nF,容差 ±20%;
  • 工作电压(交流):400V / 440V(安规应用场景下使用);
  • 防护等级:X1、Y1,适配线对线(X)和线对地(Y)抑制需求;
  • 工作温度:-25℃ ~ +105℃,适应一般工业与家用电器温度要求;
  • 封装形式:插件式,双引脚,引脚间距 P = 10mm,便于手工/波峰/插件机装配;
  • 品牌:TDK,具有良好的一致性与可靠性。

三、典型应用场景

  • 交流电源输入端的共模/差模噪声抑制与滤波;
  • 开关电源(SMPS)初级侧干扰抑制;
  • 家用电器、白色家电、电机控制器及照明驱动电路的电磁兼容(EMC)设计;
  • 仪器仪表、工业控制设备的浪涌与尖峰抑制场合;
  • 作为跨线(X)或线对地(Y)安全电容,满足电网相关抑制需求。

四、使用与安装建议

  • 按安规分配用途:X1 用于线对线(跨线)抑制,Y1 用于线对地抑制,布局时应严格区分应用位置以符合安规设计原则;
  • 温度与电压裕量:在高温或含高次谐波的场合,应考虑适当降额使用,延长器件寿命并提高可靠性;
  • 焊接与机械应力:插件式引脚适合常规手工或自动插件工艺,焊接时避免过长时间的高温暴露与机械弯曲,以免损伤封装或改变电气特性;
  • 维护与更换:安规电容遇明显变色、开裂或漏液等异常应及时替换;长期运行设备应纳入定期巡检项。

五、选型提示

  • 若系统为高电压或工业级强浪涌环境,建议在系统级进行电压冲击与寿命评估,必要时选择更高等级或并联/串联组合并配合限流器件;
  • 对空间和安装方式有特殊要求时,请确认 P=10mm 的插件布局是否匹配 PCB 开孔与贴装工艺;
  • 如需满足特定标准或获取完整认证资料,可向供应商索取产品认证与试验报告以便于安规审查。

总结:CD45-E2GA472M-VKA 为一款面向电源端 EMC 与安规抑制的插件电容,容值 4.7nF、标称工作电压 400/440VAC、防护等级 X1/Y1,适用于多种家电与工业电源场合。选型与布局时应遵循安规用途划分并考虑工作环境的温度与电压降额。

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
