FV31X222K102ECG 贴片多层陶瓷电容(MLCC)产品概述

一、产品核心身份与定位

FV31X222K102ECG是PSA信昌电陶推出的一款高压贴片多层陶瓷电容(MLCC),针对需要高耐压、稳定容值的电路设计场景开发。该产品采用1206(公制3216)标准贴片封装,属于信昌电陶高压小容值系列的典型型号,兼顾体积紧凑性与电气性能可靠性,适配自动化表面贴装生产工艺,可满足工业、医疗、新能源等领域的高压电路需求。

二、关键电气性能参数

该型号的核心电气参数明确,满足高压电路的基础功能需求:

  • 容值与精度:标称容值2.2nF(标识代码“222”),精度等级±10%(标识代码“K”),容值一致性符合行业批量生产标准,避免单批次产品参数波动影响电路性能;
  • 额定电压:直流额定电压1kV(标识代码“102”),可稳定工作在1kV及以下直流/低频交流电路中,设计余量充足,降低过压击穿风险;
  • 温度系数:采用X7R介质,在-55℃~+125℃工作温度范围内,容值变化控制在±15%以内(符合IEC 60384-1国际标准);
  • 辅助参数:损耗角正切(tanδ)≤2%(1kHz测试条件下),绝缘电阻≥10^9Ω(25℃、50V直流测试条件下),满足滤波、耦合、去耦等功能场景的损耗与绝缘要求。

三、物理封装与可靠性设计

1206封装的物理尺寸为3.2mm×1.6mm×1.2mm(长×宽×厚),适配常规贴片设备的贴装精度要求,适合高密度PCB布局。产品采用多层陶瓷叠层结构,具备以下可靠性设计:

  • 内部结构:镍基电极与钛酸钡基陶瓷介质交替叠层,通过高温烧结实现一体化结构,减少寄生电感与电阻,提升高频性能;
  • 端电极设计:采用“镍层+锡镀层”双层结构,耐回流焊高温(峰值温度260℃,峰值时间≤10s),焊接兼容性好,可过波峰焊、回流焊等工艺;
  • 外部防护:陶瓷保护层覆盖表面,抗机械应力与环境腐蚀能力强,适合工业现场的振动、湿度等严苛环境。

四、材料特性与温度稳定性

X7R介质是该产品的核心材料特性,相比Y5V等高介电常数介质,具备更优的温度稳定性:

  • 宽温适应性:覆盖-55℃(低温存储/工作)至+125℃(高温环境),满足车载、工业控制等宽温场景的长期稳定工作;
  • 低容值漂移:温度变化时容值波动控制在±15%以内,避免因温度偏移导致电路性能下降(如滤波效果减弱、信号耦合失真);
  • 平衡型介电常数:钛酸钡基陶瓷介质兼顾容值密度与稳定性,无需通过增加体积实现高容值,适配小封装高压设计需求。

五、典型应用场景

结合1kV高压、2.2nF容值的参数特点,该型号主要应用于以下场景:

  1. 开关电源EMI滤波:高压输入端的共模/差模干扰抑制,减少电磁辐射对周边敏感电路的影响;
  2. 高压驱动电路:LED高压驱动、继电器线圈驱动的高压去耦,稳定电压波动,保护驱动器件;
  3. 医疗设备高压模块:如高压发生器、监护仪的高压信号耦合,满足医疗设备的可靠性与安全性要求;
  4. 工业控制高压电路:PLC、变频器的高压辅助电路,适配工业现场的宽温、抗干扰与振动环境;
  5. 新能源辅助电路:光伏逆变器、电动汽车充电桩的高压滤波,提升电能转换效率与稳定性。

六、品牌与品质保障

PSA信昌电陶作为国内MLCC领域的专业制造商,该型号具备完善的品质管控体系:

  • 认证资质:通过ISO9001质量管理体系、ISO14001环境管理体系认证,部分批次满足AEC-Q200汽车级标准(需确认具体批次);
  • 可靠性测试:经过高温老化(125℃×1000h)、湿度循环(85℃/85%RH×1000h)、电压耐久性(1.5kV×1000h)等测试,故障率≤0.1%;
  • 批次一致性:采用自动化生产设备,容值、耐压、尺寸等参数批次波动小,降低客户电路设计的兼容性风险。

该产品以高性价比、稳定的电气性能,成为高压小容值MLCC市场的实用选型之一,可满足多领域高压电路的设计需求。

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
