FV43X471K202ECG 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本信息

FV43X471K202ECG是PSA信昌电陶推出的高压贴片多层陶瓷电容(MLCC),型号命名遵循行业通用逻辑:

  • “471”表示标称容值为470pF(47×10¹);
  • “K”代表容值精度**±10%**;
  • “202”对应直流额定电压(DCWV)2kV(20×10²);
  • “1812”为英制贴片封装(换算为公制约4.57mm×3.05mm)。

该产品属于中高压MLCC系列,聚焦对电压耐受、温度稳定性有明确要求的电子电路场景。

二、核心电气参数详解

产品核心性能可满足中高压电路的基础需求,关键参数如下:

  1. 容值与精度:标称470pF,偏差±10%,符合工业级电路对滤波、耦合功能的精度要求;
  2. 额定电压:2kV DCWV,可稳定工作在中高压环境,避免电压击穿故障;
  3. 温度特性:采用X7R温度系数,工作温度范围覆盖**-55℃~+125℃**,容值变化率≤±15%(行业标准);
  4. 封装与工艺:1812贴片封装,支持自动化贴装,节省PCB空间;
  5. 辅助参数:损耗角正切(tanδ)≤2.5%(1kHz测试),绝缘电阻(IR)≥10⁹Ω(25℃、100V DC测试),保障电路效率与绝缘可靠性。

三、X7R温度系数的应用价值

X7R是MLCC中兼具稳定性与成本优势的温度系数类型,核心价值体现在:

  • 宽温稳定:相比Y5V(容值变化±20%~+80%),X7R容值波动更小,适合信号稳定性要求高的场景;
  • 环境适配:覆盖工业级温度范围(-55℃~+125℃),可用于户外设备、工业控制等高低温工况;
  • 无极性设计:贴装无需区分正负,简化生产流程,降低装配错误率。

四、典型应用场景

凭借高压耐受与宽温稳定特性,该产品广泛适用于:

  1. 开关电源(SMPS):高压DC-DC转换器的输入/输出滤波,抑制电压纹波,提升电源效率;
  2. LED驱动电源:高压LED模组的EMI滤波与稳压,保障LED稳定发光;
  3. 工业控制:PLC、变频器等设备的高压耦合/去耦,适应车间高低温环境;
  4. 医疗设备:部分高压医疗仪器(如监护仪)的辅助滤波,满足低损耗、高绝缘要求;
  5. 通信基站:基站电源系统的高压滤波,减少电磁干扰对信号传输的影响。

五、选型与使用注意事项

为确保可靠性与使用寿命,需注意以下几点:

  1. 电压降额:高压MLCC建议按80%额定电压使用(实际电压≤1.6kV),避免长期高压老化;
  2. 温度匹配:确认应用场景温度是否在-55℃~+125℃内,超出需换NPO等其他温度系数产品;
  3. 精度适配:±10%精度适用于大多数滤波场景,若需更高精度(如±5%),需选择对应型号;
  4. 贴装兼容性:1812封装需匹配PCB焊盘(建议焊盘宽度0.60.8mm、长度1.21.4mm),避免虚焊短路。

六、品牌与质量优势

PSA信昌电陶作为国内专业MLCC厂商,产品具备以下优势:

  • 制程成熟:采用高纯度陶瓷材料与多层叠层工艺,确保电容一致性;
  • 环保合规:通过RoHS、REACH认证,符合国际电子行业标准;
  • 供货稳定:具备批量生产能力,满足中大型厂商的量产需求。

该产品平衡了高压性能、温度稳定性与成本,是中高压电子电路的高性价比选型。

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
