FV55X104K102EFG 贴片陶瓷电容(MLCC)产品概述

一、产品基本定位与核心身份

FV55X104K102EFG是PSA信昌电陶推出的高压多层陶瓷贴片电容(MLCC),针对中高压电路对“容值稳定、宽温适配、可靠性高”的需求设计,核心参数覆盖1kV额定电压、100nF容值,采用2220标准贴片封装,属于X7R介质类型的高性价比无源器件,适用于工业、医疗、新能源等领域的高压场景。

二、关键性能参数详解

该型号的核心参数明确且针对性强,具体如下:

  1. 容值与精度:标称容值100nF(对应代码“104”),精度±10%,无需额外高精度筛选即可满足多数工程需求;
  2. 额定电压:直流额定电压1kV,是该型号的核心优势,适配中高压直流电路;注意:交流应用需降额(峰值电压需≤额定电压×0.7,避免介质击穿);
  3. 温度系数:X7R介质,温度适用范围-55℃~+125℃,容值变化控制在±15%以内(25℃基准),宽温环境下性能稳定,无需额外温度补偿;
  4. 封装规格:2220英制贴片封装(公制对应5750,即5.7mm×5.0mm),尺寸紧凑,兼容自动化贴装生产线,适合高密度电路设计。

三、封装工艺与物理特性

  1. 封装尺寸:典型尺寸为长度5.7±0.2mm、宽度5.0±0.2mm、厚度1.2±0.1mm(具体厚度依批次略有差异),焊盘设计需匹配IPC-A-610标准(建议焊盘长度6.0mm、宽度2.0mm);
  2. 电极与镀层:端电极采用“镍底层+锡表层(Ni/Sn)”,兼容无铅回流焊(峰值温度260℃,持续时间≤30s),焊接可靠性高;
  3. 工艺特点:多层陶瓷叠层结构,X7R介质无极性(正反贴装无差异),降低贴装失误率;高压设计采用厚介质层,提升绝缘性能,减少漏电流。

四、典型应用领域

FV55X104K102EFG适配多类高压电路场景,核心应用包括:

  1. 高压电源滤波:开关电源、LED高压驱动电源的PFC后级滤波、EMI共模/差模滤波,抑制高压纹波;
  2. 医疗设备辅助电路:X射线设备、高压监护仪的耦合电容、高压滤波,满足医疗级宽温与可靠性要求;
  3. 工业控制模块:高压传感器、继电器驱动电路的信号耦合,应对工业环境的温度波动;
  4. 新能源领域:光伏逆变器、电动车充电模块的高压辅助滤波,适配户外宽温环境;
  5. 通信基站电源:基站高压配电模块的滤波,保证信号传输稳定性。

五、可靠性与品牌优势

  1. 品牌背书:PSA信昌电陶是国内专注高压MLCC的核心厂商,产品通过RoHS、REACH环保认证,部分型号获UL、VDE高压认证;
  2. 可靠性指标:绝缘电阻(IR)≥10^9Ω(25℃,10V DC),损耗角正切(tanδ)≤2%(1kHz),耐焊接热(260℃回流焊3次无失效),温度循环(-55~125℃,1000次循环无容值/绝缘下降);
  3. 质量管控:生产过程采用全自动叠层、印刷工艺,每批次抽样检测容值、电压、绝缘性能,合格率≥99.9%。

六、应用选型注意事项

  1. 电压降额:直流应用建议降额至80%额定电压(即800V以内),交流应用需计算峰值电压(Vp=√2×Vac),确保Vp≤700V;
  2. 温度适配:若环境温度持续超过125℃,需更换X8R或C0G介质(C0G精度更高但容值较小);
  3. 机械应力:高压MLCC厚度较大,贴装后避免PCB弯曲(弯曲度≤0.5%),防止介质层开裂;
  4. 偏置影响:X7R介质在直流偏置下容值略有下降(额定电压下≤20%),设计时需预留容值余量;
  5. 存储条件:常温(25℃±5℃)、干燥(湿度≤60%)环境存储,避免长期暴露于潮湿环境(影响电极镀层)。

该型号平衡了“高压性能、宽温稳定性、成本控制”,是中高压电路设计的实用选型之一。

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
