FV55X472K202EFG 高压贴片陶瓷电容产品概述

一、产品定位与核心参数

FV55X472K202EFG是PSA信昌电陶推出的工业级高压多层陶瓷贴片电容(MLCC),针对高压、宽温环境下的稳定应用需求设计,核心参数清晰明确:

  • 容值:4.7nF(标识代码“472”,即4.7×10²pF);
  • 精度:±10%(标识代码“K”);
  • 额定电压:2000V DC(标识代码“202”,即2×10²×10V);
  • 温度系数:X7R(工作温度范围-55℃~125℃,25℃基准下容量变化≤±15%);
  • 封装:公制2220(尺寸约2.2mm×2.0mm×1.2mm,适配常规自动化贴装设备);
  • 端电极:镍(Ni)+锡(Sn)双层镀层,兼容回流焊、波峰焊工艺。

二、关键性能特性

  1. 宽温容量稳定性
    X7R温度系数确保产品在极端温度下性能一致:-55℃低温环境中容量衰减≤15%,125℃高温下容量变化≤±15%,满足北方户外工业设备、高温车间自动化装置的可靠性需求。

  2. 高压耐受能力
    额定电压2000V DC,可长期稳定工作在额定工况,同时具备1.5倍额定电压的短时过压裕量(符合IEC 60384-14标准),降低高压应用中的击穿风险。

  3. 小型化适配性
    2220封装体积仅为传统插件高压电容的1/5左右,可显著缩小设备体积,适配新能源充电桩、医疗成像设备等高密度集成场景,同时支持自动化贴装,提升生产效率。

  4. 低损耗与可靠性
    介质损耗(DF值)典型值≤1%,减少能量损耗;端电极镍层厚度≥2μm、锡层厚度≥5μm,焊接润湿性≥90%,且镍层可阻挡锡向陶瓷介质扩散,避免介质劣化,延长使用寿命。

三、封装与可靠性设计

  1. 机械强度优化
    2220封装符合IPC J-STD-001标准,可承受工业环境中的震动(10~2000Hz,加速度2g)和冲击(峰值加速度100g,持续1ms),满足PLC、伺服驱动器等设备的抗振需求。

  2. 介质材料升级
    采用钛酸钡基陶瓷介质,经高温烧结工艺制成,介质均匀性好,减少局部电场集中;抗湿性符合JESD22-A101标准(85℃/85%RH环境下1000h后性能衰减≤5%)。

  3. 端电极可靠性设计
    镍锡双层镀层解决了纯锡镀层易硫化的问题,同时提升焊接强度,避免高温回流焊时的“立碑”“虚焊”等缺陷。

四、典型应用场景

  1. 工业开关电源
    用于光伏逆变器、变频器的高压直流母线滤波,稳定电压波动,抑制EMI干扰,提升电源效率。

  2. 医疗设备辅助电路
    如CT、X光机的高压控制模块,提供稳定的高压耦合,满足医疗设备对可靠性、安全性的严格要求。

  3. 新能源充电桩
    快充模块中的高压储能、电压分压环节,适配400V~1000V快充场景的高压工作环境。

  4. 工业自动化设备
    PLC、伺服驱动器的高压接口电路,实现高压信号耦合与滤波,确保设备在工业现场的稳定运行。

  5. 通信基站高压模块
    基站电源系统的高压配电环节,抑制电磁干扰,提升电源系统的抗干扰能力。

五、品牌与品质保障

PSA信昌电陶是国内专注高压MLCC研发的高新技术企业,拥有20余年生产经验,FV55X472K202EFG具备以下品质优势:

  • 环保认证:符合RoHS 2.0、REACH SVHC标准,无铅无卤,适配出口产品需求;
  • 质量控制:每批次产品经过容量、耐压、温度特性全项测试,不良率控制在10ppm以内;
  • 售后支持:提供样品申请、应用方案设计等服务,针对客户特殊需求可定制参数。

FV55X472K202EFG凭借高压耐受、宽温稳定、小型化等核心优势,成为工业高压场景替代传统插件电容的理想选择,可有效提升设备的可靠性与集成度。

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
