FV43X331K202ECG 高压多层陶瓷电容产品概述

一、产品基本信息

  • 型号:FV43X331K202ECG
  • 品牌:PSA(信昌电陶)
  • 产品类型:高压多层陶瓷电容(MLCC)
  • 封装形式:1812(英制封装,对应公制尺寸4.5mm×3.2mm)
  • 核心定位:针对中高压电路设计,兼顾容值密度与温度稳定性,适配工业级、医疗级等严苛应用场景。

二、核心电气性能参数

本产品关键参数明确,满足高压电路的核心需求:

  1. 容值与精度:标称容值330pF(型号中“331”表示33×10¹pF),精度等级±10%(型号“K”为精度代码),避免因容值偏差影响电路性能;
  2. 额定电压:直流额定电压2000V(型号“202”表示20×10²V),绝缘强度符合高压电路安全标准;
  3. 温度系数:X7R级,工作温度范围为**-55℃至+125℃**,该范围内容值变化≤±15%,远优于Y5V等低成本温度系数电容;
  4. 损耗特性:1kHz下损耗角正切(tanδ)典型值≤0.015,低损耗减少电路能量损耗,提升效率;
  5. 绝缘电阻:25℃下100V直流测试,绝缘电阻≥10⁹Ω,确保电路长期绝缘可靠性。

三、封装与机械特性

  1. 尺寸规格:1812封装尺寸为长4.5mm±0.2mm、宽3.2mm±0.2mm、厚度1.0mm±0.1mm,符合EIA标准,适配常规贴片焊接产线;
  2. 端电极设计:采用镍(Ni)底层+锡(Sn)镀层双层结构,兼具良好焊接兼容性与抗腐蚀性能,符合RoHS 2.0及REACH环保要求;
  3. 焊接兼容性:支持回流焊(峰值260℃)、波峰焊及手工焊接,焊接后端电极附着力≥2N(拉力测试标准),无脱落风险。

四、温度特性与应用适配性

X7R温度系数是本产品的核心优势,解决了高压电容“容值温漂大”的痛点:

  • 低温端(-55℃):容值变化率≤+15%,无明显容值下降,适配寒冷地区户外设备;
  • 高温端(+125℃):容值变化率≤-15%,长期工作下容值稳定,满足工业设备持续高温运行需求;
  • 对比NPO(零温漂)电容,X7R在高压下可实现更大容值(330pF),更适合滤波、储能等需要一定容值密度的场景。

五、典型应用场景

  1. 开关电源领域:PFC电路高压滤波、高压DC-DC变换器储能电容,降低纹波噪声;
  2. 医疗设备:除颤器高压电源、CT/MRI影像设备的高压滤波,满足生物相容性与高可靠性要求;
  3. 工业自动化:高压变频器、伺服驱动器的高压耦合电容,适配-40℃至+85℃的工业级环境;
  4. 新能源领域:光伏逆变器、充电桩的高压母线滤波,提升能量转换效率;
  5. 通信设备:基站高压电源模块滤波,满足户外环境的温度与湿度挑战。

六、质量与可靠性保障

PSA(信昌电陶)作为国内陶瓷电容龙头厂商,本产品通过多项严苛测试:

  • 耐电压测试:2kV额定电压下保持1分钟,无击穿、漏电流异常;
  • 温度循环测试:-55℃→+125℃循环1000次,容值变化≤±5%,绝缘电阻无衰减;
  • 湿度测试:85℃/85%RH环境下放置1000小时,性能符合初始参数要求;
  • 认证资质:通过ISO9001质量管理体系、IATF16949汽车级认证(适用工业/汽车场景),满足不同行业的质量标准。

本产品以高电压、稳定容值、小体积为核心特点,是中高压电路滤波、耦合的高性价比选择。

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
