FV32X221K202EEG 高压贴片陶瓷电容产品概述

FV32X221K202EEG是PSA信昌电陶推出的中高压多层陶瓷贴片电容(MLCC),专为工业电源、开关电源、医疗设备等高压电路场景设计,兼顾容值稳定性与空间效率,是替代传统插件高压电容的理想选择。

一、产品基本信息

该型号属于PSA高压MLCC系列,核心定位为1210封装X7R介质高压电容,可覆盖-55℃至+125℃的宽温工作环境,满足中高压电路的滤波、耦合、储能等核心需求。产品符合RoHS 2.0、REACH等环保标准,支持自动化表面贴装生产,适配主流PCB设计规范。

二、核心参数详解

参数项 规格说明 备注 容值 220pF(代码221) 三位有效数字:22×10¹=220pF 精度 ±10%(代码K) EIA标准精度等级 额定电压 2kV(代码202) 直流额定电压,AC应用需降额 温度系数 X7R -55℃~+125℃,容值变化±15%以内 封装尺寸 1210(英制) 公制3225,长3.2mm±0.2mm,宽2.5mm±0.2mm,典型厚度1.6mm 绝缘电阻(25℃) ≥10⁹Ω 测试电压10V 损耗角正切(1kHz) ≤2.5% 常温下典型值≤1.5%

三、材料与封装特性

  1. 介质材料:采用X7R钛酸钡基陶瓷介质,兼顾容值稳定性与高压耐受能力——相比NPO介质(容值极稳定但高压规格少),X7R可提供更大容值;相比Y5V(容值随温度/电压变化大),X7R的宽温容值漂移控制在±15%以内,适合环境波动场景。
  2. 电极结构:内电极采用镍(Ni)材料,外端电极为“镍-锡”三层结构(部分批次含银过渡层),确保焊接兼容性(支持回流焊、波峰焊),且能抑制高压下的电极氧化。
  3. 封装工艺:1210贴片封装通过自动化叠层、切割、烧结工艺制成,产品一致性好,贴装效率较插件电容提升30%以上,同时节省PCB布局空间(仅为插件高压电容的1/5左右)。

四、典型应用场景

该型号主要应用于中高压直流/低频交流电路,核心场景包括:

  1. 开关电源:初级侧高压滤波(如PFC电路输出端)、变压器耦合电容,2kV额定电压满足110V/220V交流输入整流后的高压需求;
  2. LED驱动电源:高压侧EMI滤波,220pF容值可滤除30kHz~10MHz的高频噪声,避免电磁干扰影响LED亮度稳定性;
  3. 医疗设备:如高压理疗仪、医用电源的高压储能/滤波,需满足宽温与低损耗要求;
  4. 工业自动化:PLC、伺服驱动器的高压控制电路,适配工业环境的温度波动(-40℃~+85℃常见);
  5. 通信基站电源:高压直流配电系统的滤波电容,确保电源纹波控制在1%以内。

五、可靠性与应用优势

  1. 高压耐受与降额兼容性:额定电压2kV,建议工作电压≤1.6kV(80%降额),可避免高压击穿风险;若应用于AC电路,需按峰值电压降额(AC220V峰值约311V,满足需求);
  2. 宽温容值稳定:X7R介质在-55℃~+125℃范围内,容值变化≤±15%,远优于Y5V等低压介质,适合户外或高温工业场景;
  3. 低损耗与发热控制:1kHz下损耗角正切≤2.5%,长期工作时发热少,可延长产品寿命(MTBF≥10⁶小时);
  4. 品牌可靠性:PSA信昌电陶是国内MLCC领域的成熟厂商,产品通过ISO 9001、IATF 16949(部分系列)认证,批次一致性达±5%以内,降低客户选型风险。

六、选型与使用注意事项

  1. 电压降额:高压MLCC需严格遵循降额原则,工作电压不超过额定电压的80%(直流)或50%(交流峰值),避免介质击穿;
  2. 温度限制:X7R介质不适合超过125℃的环境,若工作温度≥100℃,需额外预留10%的容值余量;
  3. 焊接工艺:回流焊峰值温度≤260℃(持续时间≤10秒),波峰焊温度≤250℃(持续时间≤5秒),防止介质开裂;
  4. 静电防护:MLCC对静电敏感(ESD敏感度≤2kV),生产、存储、测试需使用防静电工作台、离子风扇,避免人体静电损坏;
  5. 偏置电压影响:X7R在直流偏置下容值会下降(2kV偏置时约下降20%),选型时需根据实际偏置电压计算所需容值。

以上概述覆盖了FV32X221K202EEG的核心特性与应用要点,可作为电路设计选型的参考依据。

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
