PSA FV55X473K202EHG 高压贴片MLCC产品概述

一、产品核心参数概览

FV55X473K202EHG是PSA信昌电陶推出的高压多层陶瓷贴片电容(MLCC),专为高压电路场景设计,核心参数清晰匹配工业级需求:

  • 容值:47nF(代码“473”,即47×10³pF);
  • 精度:±10%(代码“K”标识,满足常规电路匹配要求);
  • 额定电压:2kV(代码“202”表示2000V,覆盖高压应用耐压阈值);
  • 温度系数:X7R(宽温稳定型,兼顾温度适应性与容值稳定性);
  • 封装:2220(英制尺寸,适配高密度PCB布局)。

参数代码与性能直接对应,便于电路设计选型时快速定位。

二、封装与物理特性

采用2220贴片封装,符合国际电子封装标准:

  • 尺寸:英制220mil×200mil(公制5.59mm×5.08mm),体积紧凑,可节省30%以上PCB空间(对比同容值插件电容);
  • 表面贴装设计:兼容自动化SMT装配工艺,焊接可靠性达IPC-A-610标准;
  • 无引线结构:减少寄生电感(典型值<1nH)与电阻,提升高频响应特性,适合高压高频混合场景。

封装机械强度满足GB/T 2423振动冲击测试(10Hz~2000Hz,加速度2g),可适应工业设备复杂装配环境。

三、电气性能核心特点

作为高压MLCC,该产品在电气性能上具备明显优势:

  1. 高压耐压性:额定电压2kV,可稳定工作在直流或脉冲高压电路中,击穿电压裕量≥1.5倍额定电压;
  2. 容值稳定性:在额定电压及工作温度范围内,容值衰减≤5%/1000小时(高温寿命测试),无明显漂移;
  3. 低损耗特性:介质损耗角正切值(tanδ)≤0.01(1kHz下),适合交流滤波、脉冲储能等应用,减少能量损耗;
  4. 高绝缘电阻:典型绝缘电阻≥10¹⁰Ω,漏电流≤1μA(2kV下),提升电路安全性与可靠性。

四、温度特性与环境适应性

X7R温度系数决定了该产品的宽温工作能力:

  • 工作温度范围:-55℃至+125℃(覆盖工业、汽车等典型环境温度);
  • 容值变化:全温区内容值漂移≤±15%,远低于一般陶瓷电容的±20%标准,保证电路性能稳定;
  • 环境兼容性:通过RoHS、REACH无铅认证,耐湿性(JESD201等级2)、耐盐雾(5%NaCl,96小时)性能优异,可适应潮湿、沿海等复杂环境。

五、典型应用场景

结合高压、宽温、紧凑封装的特点,该产品广泛应用于以下领域:

  1. 工业电源:开关电源、UPS的高压滤波、EMI抑制电路(抑制共模干扰);
  2. 医疗设备:CT机、X光机等医疗成像设备的高压发生器、储能电路(稳定脉冲电压);
  3. 汽车电子:电动车辆(EV)DC-DC转换器高压端、充电桩控制电路(耐受宽温与振动);
  4. 通信基站:基站电源模块的高压滤波、浪涌抑制(保护敏感器件);
  5. 测试仪器:高压测试设备的电容储能、脉冲整形电路(快速充放电)。

六、可靠性与质量保障

PSA信昌电陶作为专业MLCC制造商,该产品具备可靠的质量体系:

  • 生产工艺:采用高精度多层陶瓷叠层技术,介质层厚度均匀性≤±5%,耐压一致性高;
  • 可靠性测试:通过高温寿命测试(125℃,1000小时)、温度循环测试(-55℃~+125℃,1000次)、振动冲击测试(20g,2000Hz),符合工业级可靠性标准;
  • 批量一致性:批量生产时参数离散性≤±3%,便于电路批量设计与生产。

该产品可满足高压电路对稳定性、可靠性的严苛要求,是工业、医疗、汽车等领域的优质选型。

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
