FM55X104K631EFG产品概述

一、产品基本定位

FM55X104K631EFG是PSA信昌电陶推出的一款高压多层陶瓷贴片电容(MLCC),专为工业级高压场景设计,结合高额定电压、宽温度适应性与稳定容值特性,适配多种需要高压滤波、耦合的电子系统,可替代同参数进口品牌产品,兼顾性能与成本优势。

二、核心参数详解

该型号关键参数可通过编码与技术规格明确,核心性能如下:

  1. 容值与精度:标称容值100nF(型号中“104”表示10×10⁴pF),精度±10%(“K”为精度代码),满足工业场景对容值偏差的常规要求;
  2. 额定电压:直流额定电压630V(“631”为电压编码,63×10¹=630V),覆盖工业高压母线(如400V DC)等场景,预留充足安全裕量(降额后可适配更高瞬时电压);
  3. 温度系数:采用X7R陶瓷介质,温度适用范围-55℃至+125℃,容值变化率±15%(典型值),适合户外、高温车间等宽温环境;
  4. 封装尺寸:2220英制封装(公制约5.59×5.08mm),为大尺寸贴片封装,可通过多层叠层实现高压与大容值的平衡。

三、封装与工艺优势

  1. 2220封装特点:
    • 大尺寸设计:相比0805、1206等常规封装,可容纳更多陶瓷叠层,满足630V高压下的绝缘要求;
    • 贴装兼容:适配标准SMT回流焊工艺,支持自动化批量生产,降低组装成本;
    • 无极性:陶瓷电容无正负极区分,安装无需额外注意极性,简化生产流程。
  2. PSA工艺技术:
    • 多层共烧:高精度叠层与共烧工艺,确保陶瓷层与电极层结合紧密,减少漏电流与容值漂移;
    • 环保电极:采用镍基电极(部分型号含银钯),符合RoHS、REACH标准,无铅无镉;
    • 可靠性测试:通过高温寿命(125℃/1000h)、湿度寿命(85℃/85%RH/1000h)、温度循环(-55℃~125℃/500循环)等测试,满足工业级MTBF(平均无故障时间)要求。

四、典型应用场景

该型号高压、宽温特性使其适用于以下场景:

  1. 工业电源系统:
    • 开关电源PFC电路滤波:高压母线(380V~420V DC)纹波抑制,提升电源效率与稳定性;
    • DC-DC转换器滤波:高压侧(200V~600V)噪声过滤,减少电磁干扰(EMI);
  2. 医疗电子设备:
    • 高压发生器滤波:X射线设备、激光治疗仪的高压模块,确保输出稳定,减少杂波;
  3. LED照明驱动:
    • 高压LED驱动电源滤波:户外大功率LED路灯的AC-DC转换电路,适配220V AC整流后的高压母线;
  4. 工业检测仪器:
    • 高压传感器耦合滤波:绝缘测试仪、工业内窥镜的信号处理模块,隔离高压与信号;
  5. 通信基站辅助电源:
    • 基站备用电源滤波:市电中断时,确保备用电源输出稳定,减少基站宕机风险。

五、品牌与可靠性保障

PSA信昌电陶作为国内MLCC领域专业制造商,具备以下优势:

  • 环保合规:符合欧盟RoHS 2.0、中国RoHS等指令,无有害物质;
  • 质量认证:通过ISO 9001、ISO 14001认证,部分型号满足AEC-Q200(汽车级)标准;
  • 供货稳定:自动化生产线产能稳定,可满足批量订单需求;
  • 技术支持:提供选型指导、应用方案优化等服务,适配客户不同场景需求。

该产品凭借高压、宽温与可靠性优势,成为工业电子、医疗设备等领域的高性价比选择。

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
